Will a P28 ecu work at all in a 92 Prelude SI

 

Looks like you want an Integra LS ECU. P28 is VTEC which you don't have so that wouldn't be any good.

H23A &F22A ECU Swaps

In order of recommendation these are the available ecu swaps. These ecus are a direct plug in replacement.

Year & Engine type
ECU Bar Code VTEC Knock IAB Stages Available

94 B18B 37820 P74 A01 No No No stage2, stage3, stage4
95 B18B 37820 P75 A01 No No No stage2, stage3, stage4
92-93 B18B (under development)
92-95 D16Z (under development)

The H23 is unusual in that it is the only engine that has secondary intake runner control but no VTEC capability.
For exmple, the P75 Integra LS ECU will drive these engines. Hondata can upgrade this P74 for secondary intake runner control.
Fuel and ignition tables can be transferred between any of the stage 2 or above Hondata upgraded ECUs.

VTEC = VTEC Control
Knock = Knock Sensor
IAB = Secondary Intake Runner Control

I was just wondering if it will drive the car at all it is not something I want
So it seems that the p75 would work

 

hmm I don't think it would work at all...the plugs may be completely different..but I can't say for sure
