Need help with tune, Not getting enough power.

[13magero]

For some reason when i am driving the Service StabilTrak light comes on and then the Reduced Engine Power light comes on on the dash. does anyone know what is causing this problem or how i can fix it?

[GHuggins]

Most likely MAF hitting a flow setting - post tune and log...

[13magero]

How do I fix it if it is hitting a MAF setting?

[dreksnot]

Very advanced timing in the main table and no Power Enrichment, among other missing parameters in key tables.

[13magero]

im just trying to get it drivable for now.

That worked great! thank you. What did you change? I have a separate problem now. My turbo is spooling up to 15 pounds and its supposed to be a 7lb wastegate. we got an on-3 turbo kit but we have a turbonetics turbo. we have the vacuum hooked directly to the turbo housing. Do you know what is wrong?

[GHuggins]

He changed the map / maf limit setting - all you need to do is open your previous tune then go to compare and open the tune he posted - the difference will be found under engine diag - airflow... I don't recommend killing it, but on turbo applications sometimes that's the only route you can go...

[SultanHassanMasTuning]

if you have a 7lb spring, either your boost control plumbing is wrong. or check for some vacuum leaks

[13magero]

For some reason my AFR is not stable after I drive it and it leans out to 17 and 16 at an idle after I drive it and it isn't stable. here is the log. Can someone help?

[13magero]

For some reason when I am hitting 5 to 10 psi on the turbo my MAP isn't going very high or I believe is not reading the right values any guesses?

I just found out it has a 15 pound spring

I think the MAF is connected to the IAT and I'm not sure if theres a way to connect the IAT without the MAF I am running a SD tune on a Turbo LS3

[griffincox]

You can use another IAT sensor, but if you are running a Gen IV computer you would benefit tremendously from a MAF airmass measurement in addition to the SD estimation.

how hard is It to tune a MAF?

[GHuggins]

Don't bother with a turbo setup - even the OE has gone away from MAF's with the turbos... Your going to probably experience lean outs even with it and the VE dialed in due to the blow offs opening and closing... If the MAF is before the turbo - it's doable - otherwise I wouldn't bother... You can leave the MAF there for iat input and just kill it in the tune...

[schpenxel]

Just kill MAF in tune or add a separate IAT.

[schpenxel]

Because the VE table isn't adjusted properly and fuel trims are disabled?

[schpenxel]

Shows 5.5 psi boost in spot in the log

Barometric pressure is showing low. Are you at a high elevation?

Need to see tune also

[13magero]

that's what I was thinking^
