Before I can do anything with the tune file I need to make sure that you didn't have auto tune on when you took the file. I'm also gonna need to know how you set the timing what method did you use? If the timing at the car on your end doesn't match what I'm seeing on my end serious damage can occur.Steve can you take a look? Pretty new and lost here just got the iac to work somewhat today instead of hanging the idle at 2800rpm. I have major surge until the car gets up to temp even then still some. Car is a 331 with a v3 vortech 13psi non intercooled. I have just been gently driving around back roads no boost at all. I think the surge is coming from the timing table numbers being off. I was going to set them all to the same number but wanted some advice. Timing seems to be good set to 10 degrees and the fuel is set for 60lbs injectors. I would appreciate any insight.
Dyno tuning is NOT needed.... just get good datalogs and take it slow. I'll help you with the first revision to get it running better and setup a bunch of tables for you.I don't plan on really driving the car hard at all until i get it to the dyno. I just want to be safe for the next few weeks if I want to take the car out for quick drive,not planning on any wot runs.
Your VE Table doesn't match the others for boost, 170 vs 200.@90sickfox I think we may be getting somewhere, when it does idle it looks ok for a cammed engine. I have adjusted the idle settings again to try and slow the surge what ends up happening is the surge shuts the closed loop idle off because the ecu thinks you may be letting out of the clutch.here is a snip of the entries I use to look at a typical idle log
We tried lower timing, most 5.0 efi engines idle around 20* or so the extra timing is to help bring the vacuum upYour VE Table doesn't match the others for boost, 170 vs 200.
Advance Table seems a little high in the idle range, try 16.
DIY base map for stock 5.0 is 16.We tried lower timing, most 5.0 efi engines idle around 20* or so the extra timing is to help bring the vacuum up
not every car wants the same thing, the 20* I am referring to is the map from the a9l most use. as an example the diy base tune wot timing is 31* the a9l wot timing is 28* I suggest running 91 octane if you do not adjust the ign tableDIY base map for stock 5.0 is 16.
My vacuum is 18-20, maybe because of the flow from the S/C. My BOV doesn't vent 100%.
