What made me decide to get into tuning was detenation killing my first sr. It was running on a jwt ecu. All of the correct mods were sent to them in order for them to correctly tune the ecu. Everything was setup correctly on my engine as well such as base timing, tps voltage, correct (bkr7e) plugs and gaps, clean maf ect. The engine suffered much detention an blew ringlands on 1 piston and bent one rod on a different cylinder.
Other than just knowing now than mail order tunes are not the way to go because it is really tough to get right due to all of the variables still, I also have the old jwt tune saved on one of my laptops. The load scaling was setup all wrong and so was the rpm scaling. After 6800 rpms it dont care how high you rev (limiter was set to 8k) it isnt going to add any more fuel or add/pull any more timing. And where the load scale was at, after 14 psi it wouldnt pull any more timing either. What a joke for a tune that was supposedly going to get me around 400whp with a 2871r.
Now this is several years later, they may have gotten better, but a large majority of our customers are people with the 2 mentioned pre tuned ecus wanting that board out and a nistune board in. We have a very large box full of these boards. We already sold one box to someone. We dont know what he did with them but if he is re selling them hopefully they will just come back to us again lol.
