Out Of Control!!
LET dyno tune here.
If you just want to get tuned for nice dyno numbers just send me a check for the amount of hp/tq you want and I will send you a nice dyno chart with whatever numbers you please

RT has a few new things. I wasn't trying to put down Vadim. Vadim has always been good to me and perhaps if I would have paid him for my original mods he would have worked long and hard on my tune. To stay on topic I still think PC stinks and is unpredictable as evident in jcarts post.

Vadim is as good as it gets, he's one of the nicest, most knowledgeable, and passionate car guys out there.
Anyone who's ever dealt with Vadim will know exactly what Mo is talking about...outstanding customer service with a ton of knowledge.

Vadim takes care of his customers and I've been extremely happy with my VRP upgrades.

Looking at injector pulse width to determine injector duty cycle (the available amount of time versus the actual time the injector is open during an engine cycle) and fuel pressure can help you identify when you are running out of fuel system capability. Manufactures provide a limited amount of fuel for each application. The size/quantity of injectors and capacity of the fuel pump are two of the largest factors in the amount of horsepower a fuel system will support. There is normally a good bit of head room in the fuel system but it is important to verify that you are not getting close to the limits as you may very well exceed them on a cold day with dense air.
The nice thing about CAN based logging is it consists of nothing more than something (usually a 1 3/4 x 1 3/4 x 3/4 inch dongle) plugged into your OBDii or diagnostics port. Data is recorded then you pull it out and view the data after the hot lap, 1/4 mile run or blast around the streets. Logging on older cars with K-Line is much slower and there tends to be slightly less data available but it can be done. The CAN based cars allow for up to ten samples per second with large data sets where K-Line can support ten samples per second but only at dramatically reduced data sets.
I'm obviously a big fan of data. Whenever I do a programmer for an ecu, I always start with the data logger part. It is my opinion that tuning without data is tuning in the dark and tuning with ECU generated data is tuning with the exact same information that the ECU has when it makes its fueling decisions.
Lastly, I've always been a little uncomfortable using mixture data post cats, especially at part loads. This has driven me to concentrate on pre-cat mixture data which I normally get from the car's ecu. Does anyone have an opinion on this?
