thanks for help on ricardo wave query.

as we are 1st year team and decided to use a dynojet power commander with stock ecu for honda cbr f4i.
As we running out of time and no time for dyno testing .can anyone put some light on how make the maps for power commander.

i also got a spreadsheet document for generating maps for power commander on forum only.
but unable use the sheet as it seem bit tough to me.

if some one can help me way to generate the maps.

thanks

You will need a chassis dyno, engine dyno, or at very least some sort of wideband logging while driving.

You should be able to download other people's maps for your engine and look at the trends for what they should be shaped like. Obviously yours with the restrictor will look much different, but they will follow the same sort of shape for a fair bit of the time.

We generated our zero- and low-load cells by revving the engine with the back of the car on jackstands. You can use the inertia of the rear wheels and apply a little brake pressure to look at the trends for how the EGT and AFR's react, and if you have someone who is good with engines, when it sounds happier, and when the throttle response feels better.

Then we did a fair bit of the rest with a sensitive driver and a very conservative starting map and drove around, gave feedback to the guy tuning, and get it more and more aggressive.

I would not recommend this option, but it is an option, and will at least get you moving.

When we finally got a few hours of chassis dyno time, we were within about 85-90% of the hardware limitations of our package just by tuning by the seat of the pants.

You should only try this of you have no other options.

You should only try this if you have a driver who is patient, and will not try to push it on a tune that can break something with too much timing, too high EGT's, etc. It will take a LONG time.

Are you able to tune ignition and fuel with the Power Commander? Make sure that you put on a timing light and double check that the timing adjustments you make actually change correctly, check the injectors look like they're working right, etc.

Best,
