Is it spinning the tires? There is less load on the engine in the lower gears. Are you sure you're not seeing that manifest as less cylinder fill? Plus it will sweep through the timing table faster and may give odd data.

My maf is done in volts, but i think it's to be expected to move a bit. Decipha likes to have plastic screen before and after the maf sensor, it straightens out the airflow and helps settle the reading. (household plastic window screen. )

Cool, so now where are you at with it? Does it idle?

which base tune did you start with? I want to have you use the difference tool and the compare bins tool. (on tunerprort header. ) Have you tried those? It's a good way to see what you've worked on so far.

You have to cut the cranking fuel because the ecu "thinks" you have 19 lbs injectors. you're getting over 4 times the needed fuel if you have 80 lbs injectors on there.

did you reduce the cranking fuel pw? The whole table (y axis) multiplied by .23 or so? did you try clear flood mode? You'll need to post the tune.

I thought I knew what you meant. That said the cars been sitting a while, ( push power). So it's push power now, you need it running to drive so you can start pushing it again.... I'm just messin at this point. It's all good.

pushing it???

Hmmm. FN875N and Fn875D D is for drive on autos trans so I'm not sure since i'm on a stick shift car. He may not use it. I think on the write up he said make 875N and 875D match and tune D if needed.
