Cheeky...

Hi Jez...

I am being a little cheeky really... I have bought Scottys Stage 2 chip from him when he moved to stage 3 and was wondering if you can give me the part number or model of the chip holder i need to get it fitted?

And on Stage 2 with S15 GT28 BB Turbo@1bar, Saab FMIC, Walbro, Induction and HKS Hiper what is the reccomended setting for the timing? 15degrees btdc?

Cheers...

Paul

You need a 28-pin 0.6" DIL socket - you can get htem from Maplin or RS - not got the part number handy at the mo.

Ignition timing should be around 14-15 deg - all depends on your engine - just make sure its not detting.

The ultra-reliable, precision-stamped, dual-wipe contacts offer an anti-overstress feature to prevent contact spring damage. One end is indented for polarisation.
