Fun! Nice post, and good to get more data points on the 93 octane map. I'm still going to try it with 96/97 octane to see if is just a bit too aggressive on 93. I'm optimistic!
That makes sense to me. Even the more aggressive settings (over stock) are situational; I can see where the local test area might have called for a richer AFR due to heat/humidity, etc. It's great to be able to tweak to our own preferences and tolerances for safety.I had the same issue with ALL the OTS Cobb maps on my MS3 EXCEPT the "stock" 93 octane stage 0 map which worked the best, even with modifications. Some tweaking of the map turned a very good map into an amazing map. I think 10.8: 1 AFR is way too rich... even on a turbo car. It's amazing how much more you can get for setting targets to 11.8:1 (at higher rpm) and changing the rpm to boost relationships just a small percentage.
The 91 octane map is great fun. Most of us aren't too worried about problems with Ford -- especially if you keep it mildly tuned. The AP with a 91 octane map isn't a big deal for most dealerships.So are those that purchased this product for 500.00 or so, happy with the gains on the 91 oct map(s) ?
I live in Canada where 93 is not available
Also what I'm really having difficulty with, is risking the mfgs warranty by installing this product :scared:
