A good friend of mine had a GSR back in 2002? That ran an 11.7 - easily had a low 11 in it but stock diffs = wheelspin.

Was built by a mutual friend who worked at psi, tuned by Brett. He jumps in with my mate, the get around the corner, is told to stop. Mutual friend plugs in the laptop and immediately pulls 5 degrees of timing out across the board ....

You guys already know the story. Lol!


More like Gang bang.
Lol.
Sounds similar to this tune where it was set to 18deg advance to begin with and any timing taken out on the map will still be taken out on top of the 18deg already.
Will be fun

One day I'd really appreciate it if the tuning types could put together a sticky on how to tell a "poor tune" to a "good one" or direct me to a site to get some ideas.

Whilst I understand some aspects of engine tuning - some of it is simply beyond my limited knowledge.

So Mao, Rossco, TJ . . . anyone?

For the benefit of others who don't understand the essence of tuning, going back to the basics of Intake, Compression, Power and Exhaust strokes of the engine cycle is best to start understanding.

In the case of advancing ignition timing, imagine the piston moving up n down in the engine. Advancing timing will cause the combustion/power stroke to begin earlier, which in this scenario, imagine the piston not fully finishing its upwards motion, and the plug fires and burn fuel which then pushes the piston quickly downwards. This will lead to increased stress on the pistons and rings, which would then lead to detonation and damage if timing is advanced too much.

Correction: in the case of EJs, side boxer compression stroke instead of upward compression stroke.

Your suggestion is great. The scope is really big and it will need a lot of time and responsibility to do it right though.

The below GD STi already came in with Verso already. Below is the power run results.

That's my bro's car and there is a gain of another 20whp with a slight boost increase and better torque curve from a tune with the current exhaust and cosworth cai. That torque curve is shocking right now,it pulls hard up to 3500rpm and after that it's like a diesel and stays at 14psi. Will be interesting to see the gains once he bolts up the bigger turbo, headers, process west fmic, hyperflow cai and Vi-pec ecu.

Finally got down on my ass to finish off the Flash tune on the GRB mentioned a few posts ago. Installed the process West TMIC with a PW CAI. Hit 294 hp but injectors were maxed out, so I had to let my foot off the throttle at 6492 RPM.

Will post up the info shortly. I have spent countless hrs perfecting the flashes on these new 32bit ecus and anyone who claims 300+ hps on these new rexes n STis, Lol, I rest my case.

Below is the pic of the Process West TMIC on the GRB STi:
