wat ecu do i need?

[pelekeliko]

i am currently in the middle of doing a ls vtec swap. I got a 97 gsr head that i am putting on my 96 ls. What ECU am i going to need?!
any suggestions....

[98vtec]

p72 or p28. Depends if you want secondary valve control.

[pelekeliko]

haha hey bro i dont want to sound TOOO stupid. but honestly wat exactly do you mean when you say "depends if i want secondary valve control"
and wat do YOU suggest on getting?!

[CapnToll]

Only the P72 can control the secondaries in the GSR Intake Manifold. Those valves that open up in the manifold to open up the airways within working in conjunction with VTEC to make the best powerband. If you are going to upgrade to a better aftermarket manifold, you won't have to worry about it.

well for now i am going to just keep the stock IM. so i guess the P72 it is.. thanks a lot

oh ya one more thing capntoll.. do you know wat timing belt i am gonna have to get?!

Well I'll let you search up things like OBD1, Hondata, Crome, Uberdata, and phearable.net on your own to get an idea of how to prep your car for tuning.

In a nutshell, you go to the dyno and make some runs. You will check out what your Air/Fuel ratio is at, and then using a tuning program/software like I mentioned above, you will change your fuel flow to make sure your Air/Fuel ratio is in a safe zone. And unless you go with an expensive program like Hondata S300, these changes come in the form of "burning" (like CD burning) new information onto your ECU's microprocessor chip.

First thing would be to find a tuner in your area, and have a chat with them. They'll let you know what programs they can support and use.

don't forget ignition. ignition tuning is the whole basis of getting programs like Neptune over a vafc.

Errr, maybe I meant half of the nutshell lol.

[pelekeliko]

haha fasho.thanks for the help guys!..

[teggy11]

hey man. Get a p72 ecu. You are going to need a gsr timing belt and a gsr waterpump.
