90 Integra LS ECU...
 

I was at the junkyard the other day and found a 90tegLS. The engine was already gone, but the ECU was still there. I've heard that tegra ecu's can be used to replace stock ecu's in the event of an engine swap, like a ZC. Is this true?

into what car with what motor? an ls pr4 will run a zc, but the fuel curves will nto be opimized for that engine.

if anything, I'd go ZC into my 90 civic Si. The Si ECU will run it, but I've heard an integra ecu is better. A programmed ZC ECU is best, from what I hear.

Nope, I think I got the wrong generation. ZC's like the 1st gen integras (8x-89), i think. I dont know what a 90 is good for. I'll hold onto it. If anyone wants to buy one, pm me!
