I got my IIgomotiv chip in the mail today. The one that is optimized for use with upgraded camshafts. It's designed for 284/276 applications, but I'm running a 276/264 setup and iigomotiv claims it works well with that as well.
I had the Dinan chip in the car (installed when I bought the car) and I had driven back to back with a conforti installed ECU in my car a number of times. After I put the cams in we went Dinan, JC, and back and forth a number of times. my mechanic claimed he felt a difference, but we both agreed it was too minimal to warrant buying a JC chip and dumping the Dinan.
Well the iigomotiv chip is certainly a step up from my Dinan chip. The car pulls from much lower RPMS harder than it ever did. It also pulls hard all the way to redline with no noticable loss of power near or around 7000RPM like I had with the Dinan. Plus, I can now drive the car faster at part throttle with the iigomotiv chip than I could at full throttle with the dinan chip.
I know it's a decent writeup considering I put the chip in at 3pm today. But since then I have driven over 200 miles to denver where I'll stay the weekend, and auto-x on sunday. I've never been able to pull over the mountain passes (two passes about 11,000' in altitude) as easily and hard as I did today. The combo of the chip and a few other mods since the last time I"ve gone over the mountains has helped. But the chip definitely has a noticable power increase. I have no dyno numbers, and probably never will. But it feels better and the car goes like stink in comparison. Plus, I dropped almost 1800' in altitude today, and that helped the power in the car as well too. i"m loving it today, for the first time in a long time, my M3 puts me back in my seat and it feels great. Plus, I outpulled some Z28 camaro with a loud 'ole exhaust on it, and that was cool too.
HOpe that provided some insight. I bought this chip 6 months ago, and just received it today. It was worth the wait, I'm glad I held out and didn't go with the conforti. THis is measurably more powerful. Now maybe i"ll swap out to a 284/276 cam combo and see what this chip was really made for
