I'm tuning a 93 Prelude SRV with a s300 P28 and have a couple questions.

First of all what is the stock fuel injector size for this car?

Second how do I activate the electric fans with the s300 p28? Is the e fan controlled by its' own thermo switch? It's my understanding that this ECU doesn't allow you to control e fan activation???

I don't know the stock injector size. There will be a thermo switch installed somwhere in the cooling system and it should be used to control the fans. Using the external thermo switch is the proper way to do it.

Are you sure the 93 prelude srv has a thermo switch for the e fan? I'm looking at the schematic for the oem ecu and there are 2 wires for the electric fans. I'm thinking that the e fan is controlled by the factory ecu and not a thermo switch.
