If the engine is stroked, It will draw in more air per rev. The computer is set(without chip) to a certian amout of air per rev. The chip (SCT) can change the engine displacement. The will alter the Maf curve and the injector timing and duty cycle.

The computer will run on a base cold start table for a given time and then change over to the base fuel table. That would be the reason for the leaning out after a short drive. So the memeory wire will not stop you lean condition.

Do you know what type of chip you have?
I'm a SCT dealer if you have that type I can reburn it for you.
A off the shelf (hypertec,ETC.) chip will not work with you set up. You need a custom chip set up for your application. Espically with the N20.

hmm, i'll bet fast cat knows a thing or two about chips...

I thought changing the engine displacement would change load scaling, not alter the MAF curve.

Do you mean base open loop, or the startup table?

The computer uses the Maf to determine LOAD.

Cold start up table then it switches to the base fuel table.
