  1. I checked fuel pressure as my slopes where way off compared to what others had posted here and hp tuners forum and decided to investigate, I assumed too much pressure as I had 350lph pump instead of the commonly used 255 pump. During test I found 50 psi instead of 58psi at zero vac from a drop in 4bar reg. I adjusted the pressure in the Injector dynamics xcel sheet and that data with the correct pressure was a lot easier to scale. My understanding is I'd make changes to the MAP at Zero Airmass table?
  2. WOT my lambda is on target, although my STFT which I'm still logging even though 02 is disabled is adding up to 30% fuel. Im assuming this is because I'm still using na speed density settings. I tried halving the OL TPS table as suggested with factory turbo speed density, variable camshaft and etc data agian just now but still way too lean down low. Tried cylair settings aswell to no avail. Unless I'm missing a setting or turning too much on as I'm copying over all settings under speed density, cam and throttle than I'm thinking I should blend na and turbo maps, na low rpm load and boosted high mid to high rpm load and work from there. Failing that potentially mod the turbo speed density to match na down low. Either way in my application unless Im missing something it doesn't seem like jsut loafing speed density, cylair or OL tps tables will work.
  3. Thats what I'm getting at as surely both speed density tables would be way out and need modifying. If you flash factory turbo data for high comp eng it will all be way out. I'm thinking blending both is a good start but not sure. Surely there a forum members out there doing this not just tuning factory turbo engines. Necessary changes is what I'm looking for there is no real how to on na to turbo conversions. Things like cylair anticipation should we be using that, torque management tables etc Its been referenced that attention may need to be directed to desired boost tables with turbo logic turned on etc can't find any info on it just mentions from trawling through threads.
  4. @Puffwagonmate I have done bulk googling on the subject and did miss that, good info, as soon as my new reg is here I'll trial it. Whats your take on other tables when converting na to turbo. Obviously speed density and cam maps seem to be the minimum. Others suggest torque management tables, desired boost tables even without wastegate control enabled, cyclair anticipation et etc?
  5. Hey mate nothing wild just a pulsar 3582 with exhaust, plazmaman stg 1 cooler,4 inch intake, 1000cc bosch injectors and walbro 350 pump, waiting on a turbosmart drop in reg as my "4 bar" reg wasn't actually 4bar. I've done what you have suggested but seemed to be way leaner down low with the turbo Airflow maps, even when my target map was set to rich. I assumed that was because the speed density was out due to turbo eng lower compression. My thought was to blend both na and turbo speed density and cam maps to suit na comp with boost.
  6. Hoping to get some gurus input on the dos and don'ts of converting an Na engine tune to Turbo. Apart from enabling Turbo logic,importing fuel base and timing maps to suit positive pressure and removing timing from the borderline table and scalling which ever injectors you choose there seems to be no clear info on what the best way foward after this is. Some information on importing speed density, vct, ect and torque maps, aswell as enabling cylair anticipation in which I have all experimented with varying results. My ute goes well hitting target lambda under load and knock free from 5-10psi boost. Fuel trims are way out through which makes me think that I'll need to start logging cam angle, air mass data etc and start modfing the speed density maps. I just can't see most workshops doing all this in there tunes or do they just relay on fuel trims? Any advice foward welcome.
  7. Wondering if Aem x series guage will datalog into pcmtec using its obd2 interface? If not what is required to datalog wideband? Prepping for my na+t fg conversion and only have previous experience with haltech. https://www.aemelectronics.com/products/gauges/digital-gauges/x-series-wideband-uego-obdii
  8. Wondering if you can use AEM X series wideband gauge to datalog into pcmtec with is obd2 abilities? If not what are people using to datalog wideband. Haven't purchased pcmtec yet but prepping for my new na+t build. I only have experience with haltech previous. https://www.aemelectronics.com/products/gauges/digital-gauges/x-series-wideband-uego-obdii
