I've been running a custom all motor chip program (p28) for sometime now....I wasn't sure the "all motor" program was suited for my set up since its only a b20z/b16 head stock bottom, upgraded valvetrain, stock gsr cams, b16 intake manifold, adj. FPR, H22 injectors....with that program, vtec was hitting pretty loud at 5000 rpm, but it doesn't pul hard as it should. So I decided to go with a program Kenji suggested for my setup ..vtec engages at 5300 though...after 6 months later...

I put that in..drove for awhile to warm it up...punching on it, I made a fews pulls down a dead street, and during all those runs, i felt my car pull much harder then ever...even my gf thinks my car is faster..but anyways, the chip did do some magic to my car...kenji's program quiet down my vtec, i mean it doesn't scream as the custom all motor program did, but the fuel mapping/ignition timing seems much better. Felt like i got an extra 20 horses lol

 

"Chips" are not a good idea IMHO. They aren't specificially designed for your application, and without being able to customize them for what you need, it's not going to make power. Most of them are pig rich so that the people who make them can't be help liable if your motor should lean out and blow up.

You need to take the car to a dyno, or make timed runs (ie 50-70mph). That way you can tell for sure if it's faster. Quieter usually means leaner fuel mix.

Driving my car the entire day assured me this program chip is more conservatively suited for my set up...i'm sure my car pulls much harder during vtec, my body actually feels the rush.

Well definitely my car was running rich, my exhaust tip was getting smother with soot. I guess this chip is good for now as it's leaning out my vtec a little, giving better combustion...more power?

I mean what results should I expect if your mixture is too rich during vtec??
