C20Xe Ecu Swap Out


Guest A.B

Recommended Posts

After a partial rewrite I seem to have lost spark and I'm pretty sure it's ecu related. My ecu is bosch 0261203019/020.

 

Are they interchangeable with other ecu's with the same non dizzy configuration?!

The car is currently in the garage and they are quoting £125 to repair it. So my question is are they interchangeable for less or is it worth going aftermarket considering the repair cost?

Is that a partial rewrite of the ecu or do you mean partial rewire?

If it's rewrite you may need a new/second hand ecu, that part number comes back as for a c20xe calibra or a 2.0 vectra from 93-95.

If it's rewire you probably need to check connections, power and earth's.

An aftermarket ecu is going to be at least £400 if you go that route

Partial rewrite of lights, relays ect. I haven't touched the ecu but I believe it was damaged before hand went trying to sort the lights out fusing or something like that the ecu.

 

Can I just swap out the ecu with other codes or does it have to be exactly the same as I'm struggling to find the same code or do I just pay up the £125?

 

Really appreciate the advice

The bill is currently at £460 plus another £125 to get the ecu repair. The garage is being pretty vague on what's wrong just saying that it's lost spark. I'm away at uni and can't really get back to see what's going on. the garage have had it in now for 2 months working intermittently on it and it's becoming frustrating.

At 600 notes your not far off an emerald or omex ECU.i would also think a standard ECU would still be half as much altho second hand. I can't see an ECU losseing some of it's mapping,I may be wrong.

 

What was the issues other than no spark?

It sounds like you have this at a "normal" garage, and not with someone who specialises in either kit cars or the engine you are running? If so that's probably not the best way to get your issues sorted and as you are finding, expensive without any results.

The garage have done a few pinto engined 7 style cars but not a c20xe. I was recommended the garage because of this and the chaps knowledge of carbs.

 

The car has had a partial rewire of relays on the lighting system after I had a good look at it after my father switched some relays over and it smoked. When I took the dash off to inspect the whole wiring wasn't safe.

 

I had thought I'd be better off financially working the summer and sending it in to the garage than doing it myself. The ecu is being sent off to be repaired and I will see how it goes from there, if no progress is made I'll move it to another garage as my first choice was too busy over the start of the summer.

 

I'm not too bothered about the current bill so long as it's done right.

 

I will ask for further input once the ecu is repaired.

 

Can any of you suggest a garage in the Cheltenham / glos area?

I tried every travelling automotive electrician in the area and either got no response or weren't interested.

 

I don't think many places want to take on something like this! I even tried on the midlands Westfield group as a few of those guys run c20xe engines all of their garage recommendations wouldn't touch it.

 

I even asked if any of them would do it in their spare time and pay as they go or some cash upfront but nobody was interested.

As above a bit of history on the car would be good, what relays went pop, and after the rewire did it run for a while and then give up? Did the garage carry out the rewire? I would be clear with the garage that they know exactly what the problem is, otherwise they will just pick a part it could be and say it's broken and needs replaced, it sounds like you need some one who knows the car to go through and see what wires go where and if anything has been missed, or get the diagrams out and get learning !
