remap question

digger

i emailed this guy in glasgow about remapping the car and he says he will have to remove the ecu to do it as it cant be done through the port on astra 2.2 and a 48h turn around
does this sound right for 2001 astra 2.2??? dunno..

Mapping is done thru' the OBD port down by the gearstick. There is a local motor factor near me that downloads your map then sends it to Chipped UK via email. Chipped then alter the map to suit and then send a new map file back and the motor factor then uploads it back to the ECU. There is NO need to remove the ECU whatsoever!

:roll:

Interesting.. Removing the ECU would not help much I think. I know that they open up some ECU's to do chiptuning, but if you remove the cover you will see exactly.. nothing 🙂 You first have to de-solder both connectors before reaching any of the chips.
Don't see any need to do it, ECU can be flashed fine through the OBD port. It isn't very fast to do it that way, around 20-25 minutes. But I don't think that all the soldering will be faster (not to think of the damage that you can do if you make a mistake..)
