Ok, Ive got a bit of bunna to spend and Im thinking Apexi power fc commander then a visit to Mr Forrest. To be honest I dont know alot about the above or the simtec. I have a ver 4 sti which I think is standard. Would either be benificial ?

 

The Simtek is far more capable than the Apexi and £800 plus VAT for your model fitted and mapped.

 

i put a similair pthread up few days ago,im running the apexi and find its good

 

The Apexi does a job and is a good starting ECU controlling fuel and ignition and a lot can be learned from the hand held controller. Boost control is rather basic. There are lots of second hand Apexis about and it can be a cheap way to get a mappable ECU, however, the capability of the Simtek is streets ahead.
