Went for my SVA test yesterday. My car passed everything apart from the emissions. Going back tomorrow to re-sit it. Don't know whats wrong with it. They said exhaust and cat were ok. Turns out I have the standard STi backbox, but a Cusco centre section.
The car is not running level when idle. ie. the rev counter moves slightly. Also they found that some cables had been meddled with in the engine bay and I have an after market ECU and Goodridge braided brake hoses fitted.

I bought the electronic Speedo converstion from Import Solutions and it has been fitted correctly. Speedo and Odometer in miles now. Problem is, when I get to 40mph in 1st gear, it hits like a limiter, then 2nd gear at 45mph, 3rd gear at 50mph, 4th gear at 60mph, and 5th gear at 80mph!!!!! **** knows whats wrong now!!!!!

They also found that in 1st gear there is whine from the gearbox when lifting off the throttle. Anyone know what this could be?

I need to get all this sorted TODAY!
Any help would be much appreciated.

 

The speeedo calibration/installation is incorrect if it is causing a cut where there wasn't one before.

Can you post some emission test results to help: what is the lambda, HC, CO and RPM? Lambda sensor suspect if the lambda isn't 1, also the ECU map could be suboptimal for an emissions pass, and the MAF sensor could contribute.

 

I didn't recorde any of the results. The swapped the ECU with other Scoob at it reached the required 0.5 on emissions but it wouldn't stay there for the required 5 secs. When it did, the Lamada went out etc.

 

Could be just a lambda sensor, that is easily changed and cheap, £30 for a universal one.
