High idle after new MAF

[Chriskaw7r]

Hi I need help I just istalled a Lingftr 100 Maf 90mm TB from tpis and a fast 92mm intake. I changed the maf table to what lingenfelter said. I have an extremly high idle. I m guessing it's a running airflow table that needs adj. Any ideas or help would be great.It idles at 2500 then trys to stall. Then gos back to 2500. Should I just set b4349 to .0190

ok changed B4349 to .019 but it still runs rough and now I have tcs codes 1278, 1255. REP and the idle is still not right. Anybody?

Chris, post your tune/log files... someone will have the answer...

Ok here it is....97 Vette Supercharged, heads cam, headers, water injection.

Did u check the AFR? Because changing the MAF function only will change the AFR...... my point of view

What do you mean by AFR? The Airfuel ratio is my guess.

[odd boy]

yes

[Chriskaw7r]

yes

So you say the IFR table is something I should look at?

Brother, what other changes did u make from the stock file?

I didn't say IFR, do u have a wide band to check the AFR?

I would suggest that u post the stock file with the tuned one to see what changes took place

Yeah like I said the car ran fine before the Fast 92, Lingenfelter 100mm, TPIS 90mm TB, the AFR was fine before this and yes I do have Wideband. My issue is idle. I have to get the base tune down with the idle first. Then I will work the AFR and drivabilty next. These where all changes that were done and ran great before: It is Supercharged and it has a cam and 44 lbs injectors, 3.42 gears, Rev limit changes so to list what is all different is about everything. Like I said it ran great before. I just need to know how to bring the idle down I think its airflow related. Tables I have changed are IAC park to 145, MAF to lingenfelters settings, Effective area on the TB to .019. Anything Im missing?
