For the ecu connectors
Did you ever get a chance to data log this? I would like to see your tune also.
Thanks
When using this calculator, do you input @0.050" or @0.006" valve event numbers?
Did ya ever figure this out?
Is it IAC controlled? Does it have a huge cam or stock?
Just curious, mine is huge cam, e85, IAC controlled, and IAC count is through the roof on cold start up, normally fires off 3rd or 4th try.
Gotcha, I thought it had to do with limits of the ECU. Thanks
Where can i read more about this?
Thanks!
Engine checked out mechanically, no vacuum leaks on bank 2, all rocker arm stud intact and compression was normal, didn't check fuel pressure yet. Anyways, looking for opinions.
Oh, was stuck in...
Click the Compare Tab then Open compare file (express van)
Download the file you need and compare it to your current file. You can adjust your current file while comparing it, just copy what you need from the express van. I think the main thing you need to...
I did the math after I asked the question, lol. Thanks LCAC_Man!
How do you increase the table by 5%? multiply by 1.05?
Do you have pin 32 of the blue connector hooked up? (CPP Switch Signal) (wire is grounded until you push in the clutch)
Why do you have your Rolling Idle Speed all at 0 rpms and your rolling idle enable speed at 255 mph?
Post your RTT .hpt file
I'm guessing at this one, no tune file posted, but did you turn on what you wanted to RTT in VCM editor? Engine>General>Real Time Tuning> Real Time Mode might be set to disabled
Buy a wide band and tune it.
Your cylinder volume is off, should be .78453125
Highlight the whole VE table and add 8 to all the cells, should get you close. You're at 18.6 to 1, kinda lean. (Use the RTT OS for instant results)
Do you have a wideband air fuel sensor/gauge? I looked at your scan but never saw the reading.
Start off tuning the VE in the driveway, same with MAF when you get to it. Have you tried using real time tuning? It makes life so much easier with a wideband.
Tune the VE and MAF tables, stock setting is just a good starting point.
Your original VE table was screwy.
Tune the VE and MAF tables to start with.
