I have a 93 Prelude Si. I want to upgrade the fuel system. (Fuel rail, Fuel reg, etc)
What do I need for a Hondata ECU upgrade? I know I have to get rid of my P14 and get another ECU. Which one? WHat about the ODB1 ECU?

Thanx for the help.

 

get a piggy back ecu, i have one that i don't need since my car has been totaled, it was only used for about 1 months, you can have if for $195 shipped to your door. You can tune you injectors with this and your fuel delivery. you can also monitor critical engine parameters. let me know, send me an e-mail it interested syr6hi@yahoo.com

 

go to hondata's wobsite. i think i remember seeing a list of ECU options for prelude motors. i think it was either a obd-1 gsr ecu or an obd-1 civic si ecu. i assume you don't have vtec since you say you have a 93 si, so just look at what each ecu has to offer (like knock sensor and stuff like that).

 

in my h22 93 si lude i use a hondata p28 with a s200 setup. it works great!!!

 

why would he need a vafc is he has hondata

 

I need a new harness right?

thanks for all the help guys. I appreciate it.

 

No. Not if it's a p28. plugs right up.

 

if you decide to go with the p28 like i did be prepared to loose the scondaries and the knock sensor.

 

u can still use the IAB's if the use the lockup torque converter from an auto p28 ecu to run them.

 

just get a obd1 ls ecu. save some money over the p28

 

ls doesnt have vtec control....and by him having a p28 im guessing he has a vtec motor.

 

he just has a h23, hence the p14 ecu..

 

Just use the vtec wire to turn the IABs off and on the P28.
