Finally got a remap at Skuzzle Motorsport. Nick knows the MX5 backwards and half of the stuff he talked about was beyond me, but from what I could gather this is what he did:
Up on the dyno he did the first run and we got 133hp. I expected this to be higher because after I fitted the 4-1 decat manifold the car was noticeably faster, however Nick advised that would've been due to the faster throttle response. He then picked his best map with the same ecu, loaded that in and on the next run we had 144hp, an instant gain of 11hp.
Then he got to work fine tuning. He started with the fuelling, pointing out dips in the run and then making adjustments. Then he moved onto the cams and tuned those (I think he freed up 1.5 cam degrees from stock, I didn't really understand). Then he did some sort of knock adjustment, and then fine tuned again back the way he came, adjusting the cams again and finally the fuelling again.
Once all that was done he set up the map switching and programmed in 4 different maps based on the one he'd built:
1. Tuned map based on V Power fuel
2. Tuned map with race rom features:
Flat foot shifting
Throttle blip down shifting
Launch control (He enabled it because I paid for the race rom but told me not to use it).
3. Standard unleaded fuel map
4. Valet mode
After 49 dyno runs in total he finished on 150hp, so a respectable 17hp gain, but combined with all the tweaking it's really woken up the engine. All the flat spots have been ironed out and she's just so eager now
Although I don't think I've ever owned a car that gets this much attention, not that I want the attention. I'd rather just enjoy the car for what is it but you no doubt get the jealous or envious people who regard the driver as a bit of a poser.
