whoops, I should have mentioned I had set the tune up to scale the MAF. Standalone setup in C10. CLOSE LOOP - off via ETC MAF High RPM disable to...

KillboyPowerhead, Thank you for the additional feedback and for pointers on how to go about tuning the MAF and VVT. I will definitely try to figure...

Could you post your original file before modifying?

Because the car is intentionally switching lean with closed loop to hit the cats with o2. The average works out to be lean.

Try this. For the injector pulse issue, its probably a long shot. You might have a failing PCM if nothing that's submitted fixes this. Its not...

Well it is actually illegal, personal feelings or opinions doesn’t alter that and posts regarding deletes eventually get removed from this forum.

It's a Grams 90mm throttle body. They say direct replacement possible, but I haven't found any suggested specs that I could modify.

Iif I want to use this type of engine in other applications such as agricultural or stationary, it is not illegal from my point of view because this...

Bad ass build man. Curious to see the finished product once done. What tuner did you speak to that claimed they could tune this and aren't helping...

Well you are asking for something that’s illegal in an open forum that’s based in a country where it’s illegal

Could you please direct me to ask correctly next time? Everything has a price and the goal is to help each other or exchange! Thank you for your time!

It's called a gen 4x. The X is the important distinction. It's a gen4 block/internals with a gen 3 intake manifold. I had wrote the tuner to ask if...

if you ever need a stock file with your actual calibrations etc per the factory codes follow this:...

what 90mm throttle body did you use? BBK just FYI are junk, there is no good data for them, and they have issues. Likely an issue with your after...

Ask OZ to fix it, or post up a log file showing it being rich? do you have an MPVI3 or a RTD? if an RTD you are stuck with using a tuner that is part...

you got a gen 4 ecu? those are still locked and no tuning is available. or did you get a Gen 3 Mustang ECU (TC298) and you are trying to use it with...

Nope not how it works

Definitely strange, no idea what would cause it to cut fuel like that, and also be so repeatable, not looking right now but if i remember it was a...

With regards to the IAC, once an engine is warmed up it shouldn't be running or be used anymore. If it is then there's potentially a problem with the...

Unfortunately the physical MAFs seem to have a limit to how far they'll keep changing the output frequency (one of them seems to end around 935Hz)....

I think I learned the ECU goes into some type of sleep mode after a bit. I had left the IGN on and the battery on a smart charging tender while I'm...

I think you need the sensor that goes with the vehicle/PCM combination. Break out the multi meter and do some testing.

Ill attach files. Background the truck has been running with the CAI and the Magnuson for a year. With the attached tune names read ect. I went...

I would say that the car most likely has too much pulley for trying to run it on 93oct fuel. If i was running your power level I'd be running e85 or...

Yeah I understand it’s a stupid mistake. The injector data needed changed regardless. I’ve done this exact setup on a few swaps without issue so it’s...

the only thing im noticing is that there's roughly a 6-10% fueling correction at that rpm under a heavier load (80kpa). the question is whether or...
