help not sure which ecu to use
i have a 93 civic hatchback cx, it has an 89 crx si head and a dx bottom end, the car is obd1, and motor is basically obd0? which ecu should i use? i have the dx in now, but it is very sluggish

Re:help not sure which ecu to use
you need to use OBD1 or it will suck ass to step down to OBD0

Re:help not sure which ecu to use
I think it depends on the distributor you are using. the obd 0 or the ob1. I would just throw a vtec head on it and keep it obd1.

Re:help not sure which ecu to use
ok there is some confusion... i am definatly keeping the car odb1, but which ecu do i use? p28? but then what will it do about the oil pressure thing... im not sure what all makes a difference, or if using this motor will work obd1, obviously it will because i have it running now with a dx ecu, but its very slow and sluggish, not much power to it at all, so which ecu should i use?

Re:help not sure which ecu to use
use the non-VTEC ecu and get it chipped. The p28 is a VTEC
ECU and will cause problems if not connected fully. |
Re:help not sure which ecu to use
first of all, you fucked up by using an si head because you are gonna have fun getting your timing right with the distributor (doesn't line up like stock, and if it does, that don't mean timings right), which is probably why the car runs sluggish. secondly, make sure your ecu is a P06(DX) and not a P05(CX).

Re:help not sure which ecu to use
well, first of all i bought the car with this setup... id like to find a good running z6 thats cheap, but until i do, id like to get this running alright, would an si top and dx bottom be sluggish? i dont know, maybe this car is running alright and im just expecting more
|
Re:help not sure which ecu to use
no, it should not be sluggish, just slow... get rid of that setup asap... the fact that someone was gay enough to put that combination together makes me think their may be more wrong.
|
Re:help not sure which ecu to use
well the car is snappy off the start, but by sluggish i mean slow, it would probably top off at 90 if i really tried...
