Unread postby lilxtra » Sat Oct 13, 2018 3:24 pm

Decipha, Just wondering if you could look over this file and let me know what it needs.
Vehicle Sheet: Filled out and sent in
Car details: This car was just bought from a dealer: 1994 Gt AUTO, the engine is mostly an UNKNOWN quantity: it has a knock off Edelbrock intake, BBK 70mm TB, Bosch 36# inj and a Pro-Flow 80mm maf calibrated for 36# injectors S/C's ( car is not), Unknown aluminum heads and cam, shorties, 3.73's, Car has an unknown shift kit!. Car idles and runs fantastic!!
Exact issues: With the mods I've done car shifts at WOT: 1-2 at around 5500, 2-3 5700, 3-4 5500, want it to shift 1-2,2-3 at 6000
Specific areas to improve on: advice on WOT shifting

Datalog: Not sure how to convert csv to zip file

From the looks of your BIN, none of the injectors or MAF are different. Trans shift schedule is mildly different.

You have 36# and 80mm MAF in there now?

Try addressing the N/V Base and Product too.

Car has a Pro-Flow maf calibrated for the the injectors, tune is basically stock as shown. I just wanted to find out how to get it to shift higher, car idles/drives wonderfully so no reason to make a bunch of changes, although I did make some after I sent this. A 16 yr old kid is getting this car and it has enough power as is.

What should I do to the N/V base and product?

Well, I usually bring it up higher to carry the rpm up across the shift schedules. Example: make it 47.5 on the Base and 190 on the Product, set min/max learned to absolute. Doing so will require lowering the lower TP points. 1-2 wot shift to 1000 rpm lower than desired, 2-3 wot 3-500 lower, 3-4 right at.

ODB1 has a multiplier of 4 so keep it * 4 in the change. Stock 3.27 car is around 44.5, 4.10+ 50. Ford sets them anywhere between 37-40 and has very little min/max learned range. This also has to do with tire height.

you can also try and copy the 3-4 shift schedule into the 3rd gear lock.

The tune **IS** almost stock, the maf is calibrated for the injectors, car runs fantastic, idles good, no issues other than it shifts to soon so I didn't put a lot of changes into the tune. A 16 yr old kid is getting this car and no sense going crazy with the tune on a car that already runs good.
THANKS for all the input guys! It IS really appreciated!
