I am afraid that the answer is no... there are a few reasonable ones currently, and there is a good one near completion. But daily driving (which I do) is murder. I am looking for a daily driver so I can declare the Z officially a project car, and it is going to be some sort of SUV or pick-up truck
The hose is probably just a bit short of the 2 meters, to allow for comfortable routing.
For a time it did put one up for a cylinder misfire, but that happened to be unrelated to the tune. I think that no CEL should be up if the tune is good. I have read that some Z may produce CEL's for conflicts with the ECU mostly about the EVAP canister and oxigen sensors.
The latest dyno sheet I have is this one, which was right after the tune -very conservative tune, by the way-:
I think I could download the map from the car (once I get it back from the shop later this week), send me your e-mail and I will send it to you.
I am kind of keeping them as backup plan, should something fail with the Alliance ones.
