  1. @Darryl@pcmtec just having a quick look over this and correct me if I'm wrong but I believe you've put 11kpa= 3.4283, when it should be 3.2483? Which would then change the slope to 19.42 and offset to 1.61??

    Cam Timing Tables

    Sounds like yous both have confused each other but are talking about the same thing 😄
  3. Spark is used to control idle rpm. If you have a vacuum leak your spark will drop to try and maintain you desired idle rpm. So your idle spark will vary to maintain your desired idle rpm.

    @Roland@pcmtec I’ve sent you a pm.

    Any updates on a rough expected time before the release of the data logger @Roland@pcmtec?
  6. Yes you can add the torque reduction you want. Check out the how to on torque requester's, that give you an idea on how torque requester's work and how to add the torque reduction you want.
  7. @Carl as per the drawing that you attached previously and the wiring diagram below, the clutch switch is wired to ground. When you depress the clutch pedal, the switch will close and complete the circuit to ground. How I'm assuming the input works is it's constantly measuring voltage (voltage is referenced to ground/negative), so if the clutch isn't depressed than the input should be 12v but when the clutch is depressed and it's switched to ground it should be 0v or pretty close to that as there is no/very little potentional difference between the two.
  8. I’ve looked into doing something similar to this in the past as it was a question that was asked, however never had the opportunity/need to actually do it. From every wiring diagram I had looked at (mainly fg) the clutch switch was grounded.
  9. @BeerTurbo did you read the both the pcm and tcm when you read the tune?
  10. Yeah they do, that is another option.
  11. I'll try and help you out with working through the spreadsheet then as it can be a bit confusing the first time you look at it. All the yellow cells on the spread sheet are inputs and can be changed, green cells can not be changed. On the top let hand side you can see it ask for diff ratio, tyre height & Revs/km. Diff ratio should be pretty straight forward to work out and as for the tyre information there are tyre calculators online where you just put in your tyre size eg 285/30/20 and it'll give you revs/km and tyre height. Once all that is filled out you can move across
  12. There is a excel spreadsheet floating around on hp tuners forum where you can input some information and it'll help you get into the ball park for OSS for x amount of rpm. I'll try and find a link for you. It'll get you close and from there you can adjust it until your happy.
  13. Haven't actually tried myself but I'm assuming if you change the OSS values in the shift table so at 100% throttle it'll change gear at 6300rpm and set your limiter at 6400rpm this will in theory mean you should never "miss" a gear/ hit limiter, whilst still having the ability to manually shift up and down by tapping on the shifter. Just because you're changing the value from 8000 doesn't mean you can no longer change it manually (as far as I'm aware). Just like Darryl said it may be a good little safety net to stop the car from hitting limiter and potentially damage things.
  14. @will15 I noticed on auF0181 that the table has been modified massively and has some very large numbers everywhere. I would suggest returning that to stock and having another look at it, or looking at Roland's table that he posted on thursday.
  15. @will15 as Puff suggest in colder climates lower spark advance may work better, however E85 likes more spark advance due to burning slower so lower spark advance for e85 may still mean higher spark advance than what 98 will require. I live in North Queensland so our winters only get to like 15 degrees so I haven't had much experience with cold starts in an actual cold environment. From memory my crank spark is 12 or 13 degrees and run up spark 14 or 15 degrees for e85.
  16. I would try increasing your spark advance instead of decreasing as E85 burns slower than what 98 would.
  17. E85 will burn differently to what a gasoline fuel will, therefore I would suggest adjusting the the tables relating to cranking spark advance (auF0209 & auF1721). Those two tables along with the tables you have already adjusted should be able to get the car starting relatively well, there will be other tables you can adjust further refine that. But with those tables you should be able to get it starting well with the standard OS.
  18. Have you played with both fuel and spark tables, or just the fuel tables?
  19. Have a play around with those fuel enrichment tables and see what you can figure out. Let us know how you go.
  20. There is some fuel enrichment for exhaust overtemp, cat protection etc that might be causing this. There is a little write up showing these table. Have you played with those fuel enrichment tables?
  21. @Tom I'm assuming you're talking about the diff ratio, if so you're looking for Final Drive Ratio I believe
