Yeah I put the original tune back in, raised the idle airflow, disabled the LTFT's and adjusted the AFR error and its coming around.

Yeah if it's not something I missed in the tune or scan then I am going to do that.
I have a 2001 Trans Am with a 408 stroker, 625 lift / 238 dur cam, LSXR intake, 102mm TB, 100mm MAF.
I just installed NX direct port and decided to change to a colder plug before tuning for...
Yeah that would make sense. Maybe it took the added load of the fans staying on longer to reveal itself.
I was just thinking that since the voltage only started dropping since I made the...
Should I be adjusting AC pressure, delay, minimum time, etc...??
Problem only started after I changed the fan settings.
Anyone ever run into this? I dropped the cooling fan settings, first stage 190/195, second stage 200/205. I live in Florida so the fans run alot as it is but I noticed recently that after the motor...
So I bought new injectors. 42's from fuel injector connection and it seems to have solved the problem. Here is a scan from after the install if there is anyone viewing this with a similar issue....
Thanks! Just wanted to make sure I wasn't doing something wrong. I hadn't noticed that in the other sections.
Trying to add injector data and it seems like hptuners is putting in its own figures that are close but not exact. For instance- Short Pulse limit is 3.997 stock. I changed it to 2.500 and after I...
Okay, I set the PE to 13 and retuned ve and maf. Nothing I have done so far has made any impact on my injector duty though. Do you think I should get my injectors drilled or am I missing something...
Here is the latest scan with wideband connected
If you look at the scan after I installed the racetronix you can see that I am also getting knock in several places. I never had knock until I installed that pump.
Sorry. That was actually the wrong one. The the input I have been using was a pre-configured setting by the tuning school and is set at .625. So the wideband is correct.
Is this not correct?
The reason why I say the wideband is correct is because I bought the tuning school program 4 years ago and the dynojet wideband 2 at the same time and have been using the pre-configured settings that...
Fuel pressure stays at 58psi all the way through redline
To answer your question. Yes. The wideband is correct. Before the head/cam swap my injector duty was in the 80's at WOT. As far as the injector size I am assuming they are stock. I bought the car...
Look at frame 7320 / 12:17. It was raining so that was the only good run I could get in.
So I dropped the tank again, rechecked all my connections and installed a fuel pressure regulator just in case since I had the tank out again. Didn't see anything wrong with the installation. Put it...
yes. replaced the fuel filter at the same time I replaced the pump. also checked pressure between pump and filter. the drop off is coming from somewhere in the tank (defective pump, fuel pressure...
Just checked alldata. I thought that was the fuel pressure regulator in the fuel rail. Guess not. I didn't realize that it was in the module that I just had out and apart today. Looks like I'll be...
Hooked up the fuel pressure gauge at the fuel rail and got 58psi at idle but dropped to 40psi at WOT. Assumed fuel pump not strong enough. Ordered Racetronix RFPK-001 fuel pump kit. Installed today....
Good call! Dropping from 58 to 40 psi at WOT.
Did you try taking timing out of the .16-.52 range where you are showing knock? I have a similar setup and my main spark tables are a lot lower in the idle area.
