I believe so, I purchased the unit used from another member here and was told it was built by you. It was tuned by 18psi, used by the orig. Purchaser then sold to me. It was for a turbo application so I started over with a diy base map. I doubt it is the fault of the unit, as I have learned that ms/ts has a steep learning curve. I was just searching threads to try and solve my situation.
My version. Of ts was purchased on December 2013. So i was under the Impression that when I registered my unit, I was on the most current code.

Rev - I've actually gotten it to clean up quite a bit by adding wayyyy more fuel, as well as using 50% MAP based/50% TPS based... Hopefully that's the right way to go about it, as it doesn't seem to really like running 100% on one or the other. Running AE on 100% MAP results in small lean spike/stumble on throttle blips no matter how much fuel is added but seems to run great once you're moving, and running on 100% TPS gives clean throttle blips, but ends up way rich/stumbling when under load and tromping on the gas pedal.
As for updating the firmware, I'll try that after an up and coming track day - afraid I'll mess it up or make it worse if I rush and try to get it sorted now. I haven't ever updated it from what you started me with, will I lose any settings or anything in the process of upgrading?
Ryan - Adding lots of fuel to both MAP AE and TPS AE seems to be working for me. Running only MAP AE, I couldn't get rid of that first little lean spike, just seems to be the nature of the beast, guess it's a lag in the MAP signal. Are you running a BMW or Wells VTPS?

You can't use TPS based AE with the stock tps I don't think... its just an on/off switch. You can adjust the MAP based threshold and curve numbers though.
