my friend is about to do a obd2 gsr swap into a 94 dx can we run a p28 ecu. my search has been useless. we would like a p72 but we cant locate one cheap.

You can't really run the P28 unless its chipped.

I've seen a shitload of OBD1 P72s for sale on HT lol.

So yeah get either chipped P28 (for your setup/GSR) or a OBD1 P72. Both are all over ebay

you would want to run a obd-1 gsr p72 ecu. you need the iab sensor for the gsr manifold. if you chip a p28 , then you arent gonna have the sensor to open the butterflies.

You need to run the P72.. otherwise the IAB (Aka secondary Butterflies will not open) your car will run like the poo.

But if you get a new manifold.. blox, skunk, AEBS or some single stage intake manifold then yes you can run a Chipped P28

no chit .cool i guess its the p72. i heard you can eliminate the butterflies and run them open all the time. is this true . to be honest i dont even know what the butterflies are.

Not worth it to eliminate the secondary butterflies..

Honestly you can get a Intake manifold for around 150 or so for a blox or AEBS.

You can add IABs control to a P28

Most people cant solder in the tight board on the ECU.. so why risk damaging a $180 ECU and just dish out $120 for a GSR ECU

People offer services for it. If a P28 is the only ECU can afford right now, then 20-60$ to add the right hardware to the p28

thanx everyone. might as well get the right ecu and do it right the first time. last question .dont mean to sound like a nooby but was does IABs mean. hey jdm when you ganna do a write up on piston removal and upgrade step by step with all measurements needed. i have a z6 eg and i want to upgrade to zc pistons but i want to do it myself. if one already exists im sorry for asking. i really didnt know chit about the installation of parts on my car or alot of the do it yourself upgrades. i' been a ht user for 3 weeks and i am already about to do my first gsr swap(only swap). ht gives my the nuts and info to try it. you have my vote as a mod. thanx again

no need for me to do a engine tear down and build up.. i know there are at least 10 or 15 threads out there with plenty of pictures out there.

Also if you really want a in depth look at engine building pick up Omnimans 200whp video lots of details in there about building a Engine.

IAB is the Secondary butterflies in the GSR intake manifold

cool ill repost about the swap when its done . this thread is over.

Running them permanently open will result in significant losses of low-end and mid-range (below 5800 RPM) torque.
