2nd time i posted this.....!

Hey guys need some help on this ....

Okay so the 95 type eprom ecu came in the mail today so i went an hooked it up to my 99 gst hoping its in perfect working condition. pluged all the wires in the ecu, fired it up an it doesnt start... go on tuners an it says to switch spark plug wires #1 with #2 and #3 with #4 so i do an the car starts, but the car will bearly stay running.....Im waiting to send to dsmlink an i did select the the cas inversion option... A couple questions is should my car still run really bad even with the plug wires switched or is there actually something wrong with the ecu?????? will i still need to keep the wires like this even when i recieve dsmlink??? will the cas solve this problem an should i just go ahead an send it out?????
Please help wisemen.....
THANKS!!
Regards Paul

 

Not sure if its related at all, but whenever i disconnect my battery to clear a CEL, the car never runs right for a while. It takes a few miles of driving and some time trying to idle, and then ill shut it off and turn it right back on and it will be fine. I have no idea why my car does this, but maybe it has something to do with the ECU "relearning" its base map or something. I dont know.

 

If i remember correctly you cant interchange ecu's without additional wiring.I think 95-97 are different than 98-99 cars.

 

do you have to switch the injectors around maybe?

 

Yes this is true but its saposed to run decent my car will just fire up an then bearly run .....dsmlink fixes the injector wires so you dont have to do it manually.....sorry everyone IM just goin crazy over this because i want to send it out to dsmlink RIGHT NOW .....

 

its hard for me to help you because i havent had experience with the 97+ eclipses. so you did switch the injectors around though? try switching them back if you did.

 

yeah then it wont start at all ...... Something is F**ked up i put the loger on it with the eprom ecu and its not reading anything no coolent temp no throttle or anything so thats why my car will bearly run ... so im geussing i got sent a ecu that took a shit but i dont know...... damn im pissed paid 200 on ebay

 

I have had eprom ecus in my car in the past and it ran fine without switching injectors. All you should have to do is switch the firing order of for the spark plugs which it seems you have already done. If I were you I would try to borrow a known working eprom and test it in your car.

 

yeah so here's the deal im goin to send it to dsmlink regardless and hope they find out what is wrong with the ecu and are able to fix it......Thanks everyone IM hoping to god they can fix it !!!!
