GURU 951S 9a Chips for sale
Hi Guys-
Posting this to hopefully catch the S guys' eyes.
Im asking $230 for the pair. They were in a MAP kit I just bought and I don't need them.
Thanks,
Chris

Hmm.... You would have to ask Danno on that one. The major difference is the S chips have 28 pin DME chip (for later 951s). Not sure what the '87 has.

The S and non-S chips have somewhat different fuel mapping because of the differences in the K26/6 and K26/8 turbos. The K26/6 requires more fuel in the midrange because it builds boost a bit sooner. The K26/8 requires more fuel on the top end because the boost doesn't drop off as much as with a K26/6. Using the S chip in a non-S car is probably not a good idea because the A/F ratios won't be optimal.
