Spent the morning installing the new spark plugs and the straight pipe. The install went smoothly - no problems.

Now the ECU was a pain - taking the three triangular bolts off was a right problem.

Anyhow, got the ECU in - tried to start the car but it would only crank. It started for a split second and then switched off.

I put the standard ECU back in and it started straight away but I got a CEL light as I've removed the O2 sensor completely.

The green key light in the dash does not come on with the J's ECu but does with the standard one.

Could it be the factory immobiliser?

Any help will be greatly appreciated! Thanks

 

Sounds like an immobilizer issue to me. I'd contact the company you bought it from for the info to get it to work.

We try and keep information on how to bypass the immobilizer off the board.

 

Thanks Slow - but I got it from japan and I'm in the UK.

Your help would really be appreciated. PM me? and then I'll delete the info. '

I just want my car to run
