Teg or zc ecu!

Well when I did my ZC swap the guys at the import shop did it for me at like next to nothing, so they threw in the zc ecu for free pretty much. Well it went bad (POS), they gave me a 89 teg ecu for free! I thought it was a good deal but the damn car hesitates when I dont have enough RPM's I dont have a tach just standard cluster(seems that way to me). Is this supposed to happen or is this ecu crap too, I can get another ecu if this one is bad I'll get another one for free again. If I'm stuck with this ecu then well be it, I noticed a tiny diffrence when i switched over mabey its me. Mainly the hesitation when i pressed the gas, but only happens every once in a while (kinda irratating). The ZC ecu didnt do that, so the import shop is going to take a look at the ecu for me.

Ian :confused:

hesitation usually means lack of fuel. so maybe try some fuel injection cleaner, new fuel filter. that should help or solve the problem. also do you need more fuel pressure than stock ? cause maybe you need to up the fuel pressure alittle, since you got the zc swap
