Cant get my LTFT down a all!!!

[SmartOJ]

i just got my car back on the road after i lost #7 on my last engine. im not a tuner but i bought the softare to try to keep up with the car. LTFT are +25 about 99% percent of the time.i uplugged the MAF and got the same thing with high fuel trims.i even disabled ltft at one point then my stft went high not even fluctuating.ive fixed all known vacuum leaks and no exhaust leaks.did the carb spray trick and didnt find any vac leaks.i even monitored the fuel trims in the scanner with the car spray and had no change.installed smack brand new o2's,no change.can someone point me in the right direction.thanks

What are the mods??

I do email tunes for board members all the time, let me know if your interested.

To fix the Fuel trim problem you just need to dial in the MAF, with those crazy high LTFT's Id hate to see how rich you are at WOT

i also have a log with the maf unplugged if it matters to anyone

This log/tune with MAf disconnected s/b running in VE with a MAF fail. Make sure this has occurred. Based on that you are adding fueling to the VE primary and secondary (make sure you copy over the primary rows to the secondary) and the trims aren't coming down?

The tune is setup for combo MAF/VE up to 4000 RPM, then MAF only in Closed Loop mode.

With the MAF connected and in Closed Loop, set the High RPM Disable to 400 rpm and tune the MAF only. Then fail the MAF, set the High RPM Disable to like 8000 and tune the VE primary/secondary. Their are some great tutorials on this forum to read to learn this.
