im trying to learn the whole tuning thing and what not. i read sumwhere that u can use a pt3 and chip and tune it but there once was some things u cant change.

i think i saw it on pgmfi.org but i could be wrong.

I have also read somewhere years ago that you can chip the Accord & Lude ECU's. However, chipping them is basically a waste of time compared to the Civic/Integra OBD1 ECU's.

Chipping a P06, P28, P72, P75...etc, etc is your best bet. Remember that you will require a tune after chipping the ECU. Be it a street tune or a dyno tune. Most base maps are just that. A base from which to start your tune from.

it's the f22a1. i just went and checked right now cause i couldn't remember. so i'm on the prowl now for a p12. thanks for the help!

In a 93 EX? No... not if it's the original engine, and a US model... The USDM 92-93 EX have the F22A6.


The Integra GSR's P72 is also an option for tuning.



You won't see a huge gain from tuning an ECU if you don't have much done to your car. When you tune an ECU, you're optimizing it for the parts on the car. The ECU is already optimized for the stock engine from the factory, so the stock tune is as good as you're going to get. The F22A ECUs especially are tuned very well. The H22A's ECU is a bit rich, so you can gain a little by leaning that out a bit... but it's still not really enough to justify the time and effort to do it.
