The Fuel and Ignition units (which is what the Commander and Maverick are) allow +/- 20 degrees of timing. For a normally aspirated engine on pump fuel I would not recommend advancing it more than 5 degrees.
Can you set timing for the cylinders independently? Is there any benefit in performance when you increase the fuel pressure by %?We tried advancing and retarding timing and did not see any noticeably gains.

No, at the end of the day you are looking for the optimum AFR. You can achieve this with stock fuel pressure and a PCV for just about anything except high boost or nitrous applications.Is there any benefit in performance when you increase the fuel pressure by %?
I'm pretty sure you're replying to me. Just FYI, it helps avoid confusion if you include the quote you're replying toIf you look at the map you will see that we added up to 20% more fuel off the bottom in some areas. This is a big difference and should equate to better throttle response for sure. USAGUY I believe stated he felt a difference by adding the PCV to his unit.
Normally I would say there is no replacement for a good dyno tuned map but in the case of a CVT the Autotune is the best way to go. I have found that there are areas you will hit while in real world conditions that is very difficult to duplicate on the dyno. Autotune works awesome on these units.I'm pretty sure you're replying to me. Just FYI, it helps avoid confusion if you include the quote you're replying to
I took a look at the latest DynoJet offerings and I really like the PCV and AutoTune module (even the LCD unit). Regarding the AutoTune module, I see it uses wide-band O2's - potentially giving the unit a much wider range of feedback to use for fuel tuning. Would there be any benefit (stock or modified) to creating a dyno-tuned base map if you are using the AutoTune?

USAGUY,Yes I did get the Maverick to accelerate faster than the stock Maverick but it took me a couple of trips to Glamis and some fine tuning on the fuel map to get this done. I also removed the stock air box (weller intake system) and added a 58 mm TB which caused the car to need a different fuel map over stock. BTW Kelly at KMSPerformance added a bypass to the sensor for the stock Air Fuel sensors to remove the check engine light on my car.
The PC5 with autotune on the Maverick is a must if you want to improve your performance especially if you add the right mods.
My commander tb used to shut down but with the brp blk box it does not under any condition now and I have full throttle. The lag is gone now as soon as I went to kms new intake system..my Mav has full throttle with the brp box on it and has really no lag now.A Powercommander is gonna be nice on these machines, but the main problem with power production is the fact that the ecu shuts the throttle under certain conditions. Worst thing with my machine is that annoying throttle lag. Working on a standalone ecu for these, remove or set all limiters, full control of dbw throttle, (1:1 ratio, no lag or ecu shutting) full timing & fuel control. I already have BBK's, intakes, cams, etc for these motors, all we need is a way to control the engine fully, at a reasonable price.
