I have a 01 5 speed accord that will be getting a s300. Will any obd1 Ecu work or do I need a obd1 accord Ecu to put the HD in. Im basicly looking for the cheapest Ecu that will work with HD on My 01 accord with a conversion harness.

 

Hondata doesn't just go into any ecu.

You will need an obd2b to obd1 ecu jumper harness.

You are best off buying the ecu with the hondata pre-installed in it from an authorized dealer: http://www.phearable.net/shoppingcar...ages-p-39.html

If you have a turbo charged application I recommend using a 4 bar map sensor if you are going to run more then 11 psi of boost. You also should consider the boost control package on a turbo setup.

Another thing to consider is that the s300 system is useless without a wideband oxygen sensor gauge kit to tune the car with.

I know it can not go in any Ecu. I already have the obd2b to obd1 conversion harness. I'm just seeing if there are any better choices than a p28 or if that's it. I have the aem wideband and a apexi EGt gauge so tuning should be a little easier

 

An obd1 p72 ecu would be ideal if you are planning on keeping the intake air butterfly system in place. Other then that a p28 spec ecu will work just fine.

 

Good deal.. looks like ill be building a f22 a1 or a6 so i will just go with the obd2b to obd1 harness and a p28 with a s300 thanks!

 

No problem. If you have any other questions feel free to ask.

 

how about me...
I have a f23a1 converting to manual with a h22 5 speed, plans to go with a h23a dohc vtec head eventually, but for now, I need an ecu for the 5 speed swap, but would like to get one that I can use when I start my G23 Frankenstine build on my 6th gen accord?

you know so I don't have to get ANOTHER Ecu... any suggestions?

 

A tuneable ecu can be re-mapped for what ever engine setup you currently have.
