z1 ecu upgrade????

Problem is... There aren't and dyno tuners (that I know of) in Michigan for this platform. I've only been able to find one shop in Ohio that tunes the 240sx with nismotronic

Yeah, there are not many of them around. I know a few places that'll tune haltech stuff. Not many do nistune.

One way would be to get nistune, and do data logs, and send them to a Z tuner. Then have them build a tune off of your logs. Remote tuning can be a pita, but sometimes that's all you got to work with; unless you trailered it to a shop.
