in my ongoing attempts to increase HP on my prelude, ive started reading things on OBDI conversions. Is it possible to just change the ECU and wiring harness or are you having to change the distributor and injectors as well?

Anyone done this out there? HELP!

thanks!

You have to change the distributor. You have to change injectors if you use a 4Gen VTEC Prelude ECU. If you use a GSR ECU, then you can use stock injectors, but you must have the ECU remapped to work with the H22.

So you HAVE to use the 4gen injectors with the 4gen ecu...before you said that the stock 5gen would work...any reason for the change? found out something new?

Technically the 4Gen ECU is made for peak and hold injectors. You can use stock 5Gen injectors, but I don't recommend it. I would change injectors to peak and hold instead of saturated (like the 5Gen's).

okayyyy, so how does one re-configure a GSR ECU to prelude specs????

 

[mugenman]

is that the previous model integra GSR? ie 91-93?

 

[Guest]

You have it reprogrammed (about $300, depending on the shop). It's a 94-95 GSR ECU.

If anyone is interested in a conversion, I'm selling my set-up. It's a 95 GS-R ECU reprogrammed to H22A specs, and OBD1 distributor. E-mail me if interested.

sun,
why you selling your setup? going to a stand alone system?

 

[mike2016]
