Roland@pcmtec Posted August 9, 2018 Share Posted August 9, 2018 Flex Fuel is now available for your Falcon using the stock PCM coupled with our custom operating system. The flex fuel custom OS utilises the second O2 sensor on BF/FG as the flex fuel sensor input. This will require a converter (zeitronix or other) to convert the standard flex fuel PWM signal into a 0-5v signal. Pirotta Performance has developed a plug in loom for the O2 sensor for this purpose. The BA Falcon uses the boost sensor input. The operating system works by duplicating the main boost, spark, fuel and cranking tables. The OS then blends between the standard map (98) and the new map (e85) depending on the alcohol %. Each table has its own configurable blend ratio so you can blend in a non linear fashion if required. Eg you can run 100% of the e85 boost map at e70 but still keep a linear blend for spark. The custom operating system costs 4 credits to upgrade an existing license ($100) or 7 credits to license from scratch ($350) which makes it MUCH cheaper than any of the after market solutions available. Here are some screenshots of the new tables that are available by default. The wizard then allows you to pick and choose extra tables to be blended. http://www.fordxr6turbo.com/forum/uploads/monthly_2018_08/image.png.ecedb3bc19bb1235844f359f8c2f862d.png 3 Quote Link to comment Share on other sites More sharing options...

Roland@pcmtec Posted August 10, 2018 Author Share Posted August 10, 2018 First round of testing complete by Stathi at IMS today with great results. We have the second o2 sensor reading 0-5v and all maps blending. Finally we just need a few more tweaks and to implement the variable stoich calculation and we are ready! Hopefully have everything read for public release next week if all goes well. 3 Quote Link to comment Share on other sites More sharing options...

ebbarra Posted August 20, 2018 Share Posted August 20, 2018 Is there any way of making the upstream 02 sensor read a 0-5v wideband for a better span in the cal? I.E. 5v output from a Innovate or TechEdge. Might be handy for datalogging when it comes around? Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted August 20, 2018 Author Share Posted August 20, 2018 The issue with this is the wideband doesn't emulate a narrowband, so all the self learning logic would no longer work correctly. There are other possible uses however that the wideband input could be used for. Quote Link to comment Share on other sites More sharing options...
Seanno Posted August 21, 2018 Share Posted August 21, 2018 Springy performance has posted online about the plug and play flex fuel kit, does that mean you guys aren't to far away from releasing? I'm booked in for some work done and a tune in a couple weeks so hoping if this is available I'll be able to get flex tune done at same time Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted August 21, 2018 Author Share Posted August 21, 2018 We are very close yes. Just finalising the update to the Editor software to facilitate the custom OS, the actual operating system itself is complete pending final testing. Danny @ Springy has tested his kit with the Custom OS successfully interpolating between various E85 blends already. I don't see any reason why you won't be able to get a full flex tune in the coming weeks. Quote Link to comment Share on other sites More sharing options...

Roland@pcmtec Posted August 24, 2018 Author Share Posted August 24, 2018 This is now available! Includes extended resolution spark maps, flex maps and boost by gear. Springy Performance are offering a flex fuel plug and play kit including a flex sensor, fuel fittings, zeitronix or blueflex converter, plug and play O2 sensor loom and an optional ethanol % gauge. Pricing is currently $1090 Alternatively you can build your own however to cut down on support costs we are only providing support if you use the flex kit as this is a proven and tested product. If you wish to use dual maps, rotary dial for variable boost etc you can simply switch 5v on pin a37 (rear O2 sensor input) to trigger it. To get access to the new OS send us your tune and we will convert it to the new OS. This will be automated in the next version of the editor. 1 Quote Link to comment Share on other sites More sharing options...

On 8/21/2018 at 5:20 PM, Roland@pcmtec said: PCMTEC Editor Version 0.72 has now been released as of 21/8/18 Custom operating systems cost 5 credits (4 to edit, 1 to flash). If you have already licensed the vehicle you will be offered an upgrade license for only 2 credits, this is all automatically determined when you press "License Vehicle". I emailed my licensed file through a little while back so I could have a look at the boost by gear and map swap over etc and a custom os was emailed back, without flex fuel support. I am keen to have the flex fuel option however. I wonder if you still have my original file? Could you please clarify what is "automated in the next version of the editor"? I'm just a little confused about the automatic update and the 2 credit update. At any rate I will go ahead with the flex option so will proceed based upon your advice. Thanks mate.

Roland@pcmtec Posted August 26, 2018 Author Share Posted August 26, 2018 Hey Puffwagon. Darryl is looking at yours on monday. So with version > 0.72 if you license say HA*** for 3 credits, then we provide you with a PCM** custom os (we use PCM** prefix for the Custom OS) it will only cost you 2 credits to license (total of 5). If you have never previously licensed the car and go to license the custom OS it will cost 5 credits. The editor automatically determines whether to charge 5 or 2 credits based on your prior licenses. I will be writing up a Custom OS HOWTO shortly that describes all the new maps and how to set them up. This will continue to change over time as we make it more and more dynamic within the editor. Eg in the future you won't have to send us a file, it will just be a toggle in the editor and you will be able to toggle which maps you'd like to interpolate opposed to all of them being added. 1 Quote Link to comment Share on other sites More sharing options...
Puffwagon Posted August 26, 2018 Share Posted August 26, 2018 Thanks for the reply mate.

Puffwagon Posted October 9, 2018 Share Posted October 9, 2018 (edited) I posted this on another forum but i thought it'd be worth posting here too. My thoughts are regarding fuel economy, longevity of hardware, the use of very small amounts of e85 to change from low to high boost as well as a possible idea for staged fuel pumps. I'll just quote it below. "Run a 12psi 98 tune that blends into a 22psi e85 tune. Run the boost up high earlier in the blend so even at 5% ethanol it goes to 18psi but you can leave the timing out of it until the ethanol content is higher. That'll mean you'd have a fairly ordinary car with straight 98 but with even a small amount of e85 it'd come alive. It'll keep your car alive for longer too cos it'll last for ages at lower boost and even a stock motor should stay alive for a bit of high boost work. You'd definitely save some money running 12psi on 98 over 22psi on e85. Also a random idea @rollex how about a secondary fuel pump output that is activated by various tunable conditions and/or parameters such as map and ethanol content." Anyhow i can't wait to try some of this out for myself. I just gotta pull my finger out and fix my car...

How would you keep the fuels separate? if you mix in e85 froma secionddary tank during boost, its going to go back to the main tank as part of the return system? Are you perhaps thinking a second set of injectors and a separate e85 fuel system - activated on higher boost levels? Or do what the Japs used to do back in the verry early 90's and install a 7th injector in the intake track to inject extra fuel? similar to a wet nos setup?

Puffwagon Posted October 11, 2018 Share Posted October 11, 2018 I'm talking about separate ideas in that post but to be clear I'm only referring to one fuel tank and 6 injectors. Of course it could be utilised in other ways with water/meth injection etc. You don't need to keep the fuels separate. To raise boost but still run primarily 98, at the bowser you'd just add a few litres of e85 to your remaining 98 in the tank. As soon as the very low pre tuned e85 threshold has been reached, the boost would come up. This is a way of juggling a low/high boost condition with just using fuel content whilst still keeping the economy of 98 octane. Straight 98=low boost, e5=high boost with appropriate but similar timing. Perhaps e10 would be more suited to compensate for the boost change and this is what the tuner would have to work out. There are more variables but this explains it enough I think. If you were referring to having a secondary pump output then my reasoning is this; with normal street driving fuel demand is low and as such you don't need multiple electric pumps unnecessarily loading the electrical system and heating up the fuel from excessive circulation. You also don't need as much fuel pump for 98 octane vs e85. If we had a secondary pump output then you could run a smaller pump while cruising or at lower power levels and when various conditions are met such as map, e85 content, road speed etc, you could have 2 or 3 or more pumps running. As the secondary output would activate a relay system, you could even incorporate a hobbs switch to further stage the pumps eg: 1 pump for 98, 2 pumps for e85 and the hobbs switch can activate the third pump at a preset map. I hope this clears it up. Quote Link to comment Share on other sites More sharing options...

Puffwagon Posted October 11, 2018 Share Posted October 11, 2018 That's right. You can have a high low boost setting with just a touch of e85 added to the tank. Perhaps integrating a resistor and switch/s setup with the ethanol content sensor signal/wiring, you may be able to achieve the same thing without using the actual e85 content for feeback, while still running a full flex tune. There are so many variables to achieve slightly different outcomes that there isn't a one size fits all approach to it. Quote Link to comment Share on other sites More sharing options...

Ok I think I've got it right?! See the bold and crossed out parts, if that makes it correct? I have the workshop version with the custom os and have had time to look through it, so you're right there, PCMTEC can blend both maps and plenty more. Better yet you can blend maps in a non linear manner which ties in with my previous statements. It shows how, with some creative tuning, you can have multiple boost settings within a single tune without having to install additional hardware. Care to clarify what is amusing about using PCMTEC aka the standard computer to control boost? While I may have missed something, I have yet to find a more comprehensive boost controller than the integrated one.

Roland@pcmtec Posted October 11, 2018 Author Share Posted October 11, 2018 BeerTurbo there are 3 blend ramps. One for fuel, one for spark and one for boost. These are 10 point lookups so they can do anything you want really, it can be linear, a curve or a complete step change (eg you've wired in a switch). It is simply an analog input so you can wire in a potentiometer to have variable boost or any combination you want. Quote Link to comment Share on other sites More sharing options...
Puffwagon Posted October 11, 2018 Share Posted October 11, 2018 While your around @Roland@pcmtec, what do you think about the idea of wiring in a switch and a resistor in conjunction with the e85 hardware? In theory you could switch between the ethanol content signal output (or input?) and a set voltage signal eg: 1 volt, so you can run high or low boost on 98 with stuff all e85 in the tank but let the sensor take car of the higher (than the low set point) ethanol content tune? Any problems there anyone can see? Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted October 11, 2018 Author Share Posted October 11, 2018 So wire in a voltage adder? I guess you could do split range e85 blend ramps then. Eg 0 to 0.7v is 0 to e85 low boost then 0.7v to 1.6v is 0 to e85 with high boost. The issue will be the switch over point if you are at dead on 0% ethanol on high boost it could toggle to the e85 low boost map. I think you could hack it together so it works though. Might be a bit of work to calibrate it but should be doable. Quote Link to comment Share on other sites More sharing options...
Puffwagon Posted October 11, 2018 Share Posted October 11, 2018 I'm not an electrical guru but from what I've read you can use some types of resistors to drop voltage. This is what I was looking at. I figured that there would be a stable power supply somewhere to be tapped into. The switch idea is having either the e85 sensor output or a fixed voltage sending a signal to the pcm but not both at the same time. You would want these voltages to be identical as much as possible at the chosen swap over point. You would also have to use the e85 content sensor signal to get proper fuelling with much more than 5% ethanol. With the right fuel calibration you would be fine to run a 5% variance in fuel from 98ron to e5. And yeah, you would need to get the tuning pretty spot on with such a small range being used. I guess this is more of a self tuned and driven kind of thing as you'd have to know what's going on and how it all works. Quote Link to comment Share on other sites More sharing options...

Roland@pcmtec Posted October 17, 2019 Author Share Posted October 17, 2019 Power steering support is not implemented yet, only the boost sensor so we recommend using a turbo PCM and using this input. No one to date has done a Flex kit on an NA BA so I'm not sure if the NA PCM has the boost input available. Some of the gas BF/FG models do have have it so it may be the case for the BA as well. You really want to use the turbo PCM anyway as without the built in boost controller you miss out on great stuff like boost by speed/gear and boost by ethanol content.
