ABS - re-commissioning after engine conversion.

[cjb1]

Anyone on here know how to set up ABS on a Corsa after fitting a Z20LET Astra GSi engine?
The original 1.2 SXi has ABS but the GSi ECU doesn't recognise the system. Does anyone know how we can re-commission it to have the ABS operating properly.
We live in Aberdeen so any local expertise would help or anything on here might get us around the situation?

Can't help you directly, but there are some very knowledgable guys over at corsasport forum. There are a lot of conversions done by the members.

I'm not a member but regularly check out some of the projects (a few have moved on from corsa's).

Thanks Tommy, do you know the link to Corsasport?

I wouldn't usually do this and fall into that category of purely trolling PH poster... But...

General Chat / Help Zone would be the place to start if the search function is working. Projects and Builds is a sub forum in general chat - there are a couple of monster B's running C20LETs and various other stuff.

I understand it's free to join, with a subscription option avaliable.

Good Luck!

Haha, it had crossed my mind, but I'm in a good mood today

Don't know much about vauxhall but if both the corsa and astra use the same model of ABS then it is as simple as recoding the abs ecu to talk to the pcm.

You'll probably need a dealer to do it though.

The question is however why it's not working, basic ABS doesn't need to talk to the PCM, it's only when TCS or DSM is in the mix, so most likely it's actually working as the basic ABS, you just don't have the advanced functions.

Thanks for that, we'll follow that route to investigation, hopefully it will sort out the problem.

sounds a mental project.

A bit more detail now not from the phone... ;-)

I looked into Bosch ABS heavily while I'm building my kit car (decided not to bother in the end) and basically the serial of the PCM (aka the engine ECU) is encoded into the ABS ECU (which also handles traction control, stability management, brake distribution etc) as a security key. If you change PCM or ABS ECU's then you need to go in and change the serial. It's simple to do but you both need the hardware (I believe it's done over the K-line) and there is a login/password on the ABS ECU itself. I found the majority of the information regarding VAG cars and with those when you 'recode' you specify the vehicle engine, brakes etc. You may find even if you get in that your engine isn't an option.

However on a lighter note for the simpler ABS ECU's it might be that the error is coming from the ECU and just a case of reading the codes and clearing the error.

Of course I only looked into Bosch and I have *no* idea about what ABS GM cars use.
