Anyone know a company...........

..............................................................that I can send my A9p to get reprogrammed. I just want to give ship them my computer. Give them my engine spec's(cam info, head info, valvetrain, rear end gears, etc.,). And just have them reflash my computer. Without having it dyno'd. I'm not looking for a perfect tune with this. But I need my A9p reflashed for 24# injectors. So I figured I would see if anyone knew where I could it all done at.

The A9 series of computers is not flashable and the EPROM is soldered in place. You would need a custom tune & a chip burned from the dyno results. The custom chip is plugged into the diagnostic port on the computer.

There is no info about your car's model year or mods, which make it hard to tell what's in your car. You may not need 24 lb injectors, but there is no information provided to guide us.

That's why it is a good idea to use the sig under the user control panel (User CP) option. It allows you to post your car year & mods, which help greatly when troubleshooting things. No, it is not there for us to snoop and see any "Secrets" you have hidden away under the hood. Be a good stangnetter and update your sig for future reference & don't keep us guessing.

theres a reason why the mods arent in my sig. THEY AREN'T IN PLACE YET!!! But I am putting in a 347(11.5:1cr), tfs stage III cam, track heat heads, tfs r series intake, 1.7 rr's, 75mm throttle body, 80mm maf(maf conversion in process), msd dizzy, jlt cold air, 255 fuel pump, 4.10's in the rear. I think with all that I'm going to need at least 24# if not 30# injectors. I'm still building which is why it isn't listed.

Please list this stuff in your sig, even if it is listed as 'Work in Progress'

I think my sig is this way now...?

A chip as you are describing is FAR from ideal. In fact, I would suggest just sticking with the stock ecu, and using a GOOD 'calibrated' MAF for what you have planned. Start saving some money, and get a custom tune when you can.
The car should run fairly well on a stock A9* ecu, but you will gain drivability and performance with a custom burned chip.

What is the 'calibration' of the 80mm MAF you plan on using?

i havent bought the maf yet. the maf has to be matched to the injectors. so before i buy my maf i want to make sure the size of the injectors i need. so i can get an ecu recal'd for em.

Injector HP ratings: divide flow rating by.5 and multiply the result by the number of injectors. This uses a 100% duty cycle. These ratings are for naturally aspirated engines.

Example:
19/.5 = 38, 38 x 8 = 304 HP
24/.5 = 48, 48 x 8 = 384 HP
30/.5 = 60, 60 x 8 = 480 HP
36/.5 = 72, 72 x 8 = 576 HP
42/.5 = 84, 84 x 8 = 672 HP

The preferred duty cycle is about 85% maximum, so for a safety factor multiply the final figure times .85.

304 HP x .85 = 258 HP
385 HP x .85 = 326 HP
480 HP x .85 = 408 HP
576 HP x .85 = 490 HP
672 HP x .85 = 571 HP

Remember that the above ratings are at 39 PSI. Increasing the pressure will effectively increase the flow rating. Example: a 19 lb injector will flow 24 lbs at 63 PSI, and a 24 lb injector will flow 30 lbs at 63 PSI.

Any idea on where my HP will be?

That ranks right up there with the next lottery pick 6 numbers and win. If I could accurately do that, Bill Gates would be asking me for advice...

According to Desktop Dyno, which has been pretty accurate for me in the past, i was able to arrive at a range of 400-450hp at the crank.

Keep in mind, i wasnt able to nail down your exact parts in the files, i had to use a stage 2 cam, and im not 100% sure about the head flow file they have, but this is a good ballpark for you.

without knowing what you are running for exhaust, im guessing shortys, i would say closer to 400hp.

Man thanks. I had a desktop dyno program. But I moved about six months ago and lost the disk. But that is plenty info for me. Also all the HP I want/need. Looks like 30# injectors it is.
