I was thinking that also, I was choosing 45 because it is close to 43.5 and easier to accurately set the values to while looking at the fuel pressure gauge.

Try getting those files now..
Tried to compile my tune and this warning popped up.
I emailed you the .lst file
Do you have any idea what is going on here? Will the car run if I try and flash it with this compiled using the test assembly file? Should I continue using the functional .asm till you get a chance to look at this?
send me the .lst file also. i can probably help
89 Voyager LE, 2.5T2 - rest in peace
87 Charger Shelby T2 (2.4 conversion in process)
Just sent you the file.
No, don't use it. It won't work.
Threw new plugs in the car yesterday, switched fuel tables and pulled some more timing out of it, set it to as low as 11 degrees advanced, I re-set the fuel pressure to 45psi base, drove the car last night and its close, need to pull a little fuel out of the density factor for full and part and it is about dialed in. 26psi on premium fuel feels pretty good! Car is running much better on part throttle too now, no more going rich, it runs 13.5-14 under low boost. Making progress!
Any update on getting the staging limiter and dual boost controller working? Thanks
I am trying to get the premium fuel tune dialed in before I switch fuels, but I can't get rid of the last bit of knock at 25 psi. How much timing is safe to pull? My afr's are right at 11.5, but I am still getting the knock sensor to register too much voltage. What is a safe amount of timing retard? I am currently at 11, is it safe to pull a couple more degrees of timing with out egt's climbing too high. I do not have an EGT gauge so I am trying to be conservative and not melt anything.
Tune is dialed in now, did a few pulls on the way to work yesterday and today!! The check engine light never came on, so no knock was picked up. Car is pulling great! This tune is for 75 lb hr injectors ad 45 psi base pressure. Boost is set at 25 psi using the factory boost control. Is there anyone interested in getting this tune from me, this is for the SBECII TIII Ecu only?
I am swapping the injectors for 120 lb/hr ones and starting my E85 tune very soon.
Swapped my injectors last night and installed my big ones. (1136cc @ 43.5 psi) getting a couple of new issues, still on 93 pump gas:
Car is idling higher and having issues getting below 1000rpm.
After coming to a stop and letting the car idle down, when I go to accelerate from the stop, the car nearly stalls, then starts going, afr's go super lean at that point. How would I adjust this?
After taking off, car runs pretty good on the big injectors.
All I did was take my dialed in 72lb tune and scale it for the larger injectors, I also updated the battery offset table to values supplied straight from precision (injector Mfg for the ones I'm running). I'm sure the tune needs some fine tuning before switching to e85.
Log your PW at idle. I bet its insanely small. Its hard to control injectors at very small PW's.
The pulsewidth with the 72's was .24 @ 1000 rpm.
The 110's are logging .17 @ 1300 rpm.
What's the stock idle rpm?
OK, what's the latency at your battery voltage? Close to that?
.70ms @ 13.9v
So, your commanded PW is less than your latency. That's the problem. Those injectors won't flow a small enough amount of fuel to idle.
I got the 72's to idle and the latency was twice the pulsewidth of the idle value.
You can probably play around with the latency and maybe get it to work OK. But, I think you'll always be over fuelled at idle.
I'll play around with it, I can say the afr at idle is right around 14-15 according to the gauge. Car will most often be on e85 so these should help.
