Psykotuned LNF

No kidding on how lean the direct injection engine runs. It holds around 14.7 and even goes over 15 near wot! When I was at the dyno, the operator almost shut it down for running so lean, until I mentioned that DI runs much leaner.
I have 3 interceptors... in total, only 3 parameters are from the ECU. The other 3 are analog inputs.
i was going through the hpt file last night. i thought there was going to be a lot more tables to deal with than that. thats kiddy **** right there.
maf, 4 timing tables, pe. seriously? thats it?
steve, you sent me a stock file correct?

Oh, that wasn't stock. But yeah these cars are really sensitive to changes you make, but there's not much to them.
Post up some numbers when you get it on a dyno!
Its amazing what just a few tweaks here & there can net with these pcm's, similar to how you can make gobs of hp/tq on diesels.
One of our tunershops just made upwards of an extra 65ftlb & 30hp with just tuning alone on their test solstice gxp so there is tons of power to be made.

i wouldn't worry too much on the injector control, due to the whole lack of upgraded injectors. the timing tables seem a bit small for ultimate control. im not worry about dwell timing because these things are like ls1 coils. they can fire through a bucket of water.
i knew i should have brought my laptop to work today

The high pressure fuel pump will max out before the injectors, thats what you need to look at.

Using the flow number for the pump that I found assuming 6000 rpm & .6 BSFC and that the density of the test fluid was the same as gasoline I calculated ~400hp would be the pump limit. Now it all depends where you are making peak power as the HP pump flow rate is dependant on RPM.

Please tell me you flashed your car already!

For reference, if the actual pressure is 1500 kpa less than the commanded or the fuel pressure adjustment is out of the range of -/+ 2,500 kpa for 4 seconds you will drop a code. If HP tuners lets you see these parameters you should take a look at it just for your own knowledge.
