Hello there,

I've got a Gems ecu in my '99 wrx and we can't get the idle mapping right.

It needs to be very rich to make it run right. When we decrease the fuel mapping it stalls. What else can we try to get this right ?

The rest of the mapping goes fine and it runs well (about 390hp on the engine at 1.4bar).

The car has the following mods;

- 2.5 closed deck engine
- Forged ROSS pistons
- Forged connecting rods
- Sti bearings
- HKS FMIC
- HKS SSQV
- HKS Garret Turbo (GT 2835)
- 740 cc injectors
- Extra cold spark plugs
- Invidia Downpipe
- Invidia Middenpipe
- Varex backbox
- Apexi AVC-R Boostcontroler
- Lambda-Link
- Knock-Link
and some more stuff

Thanks in advance

Derk
