(*Note: I actually copy and pasted the scaling numbers from my MAP...you might be able to copy and paste them into yours...dunno.)
First thing is first for the Timing Map...you've got to Scale it. (TPS read is %...so at 0 - 1 % your foot isn't even on the gas, from 0 - 30 % your at DD, at 75 percent your foot is heading to floor and then from about 98 to 100 % you're trying to peel the paint off. Open up the datalog file. Look it over. See what the % Throttle was for DD...and what it was at when you were getting on it.) Since your TPS reads in % you obviously want your scale to range from 0 to 100.
This is my actual Ignitin MAP TPS scaling:
It looks like this:
100
99
98
84
78
72
66
60
54
48
42
36
30
24
18
12
6
If you notice, I choose smaller values at 98% and up. That is because when I'm at 99% TPS and higher, I'm at WOT. The value will vary a little bit from 100 to 99. It varies. Your datalog will answer what yours does.
Now, you've got to scale the RPM ranges. This is my actual Ignitin MAP RPM scaling:
It reads: 1000 2000 2900 3000 3200 3400 3600 3800 4000 4200 4400 4600 4800 5000 5200 5400 5800 6000 6200 6400 7000
Now, where do you think you've got enough air coming in and enough RPM to spray your shot? I start spray at 3000 RPMs all the way through my ranges. Therefore I need to retard timing from the 3000 RPM Breakpoint up to 7000 RPMs (Yes...I understand we don't hit 7000 RPMs but I want to go a little past 6200 where I shift at just incase...learned about the 6200 from the datalog. See what yours is if your in an automatic.)
Ok, scaling is complete. Time to actually retard some timing. (Refer to your spray kits suggestions...I run ZEX 82021, so I will be using their suggested numbers, I'd assume though everything is probably similar if not exact. 55 Shot = Not retard. 65 Shot = 2 Degrees. 75 Shot = 4 Degrees)
Now, if your spraying at WOT (99% - 100 %) and at 3000 RPMs on a 75 shot you're going to pull -4 degrees from those value boxes. Pretty simple. (My pics suck...so think of this as playing battleship...) Click on the 100 TPS, 3000 RPM value box and drag the mouse until you hit the 99% TPS, 7000 RPM box. Right click. Select Set Value. Type -4. Click Ok.
Guess what? Your 4 Degrees are pulled. Time for more fun...go datalogging. You'll notice when you look at your log this time, the AFR has changed and the Ignition Trim has changed...among a few other things possible but those are the two most important.
Now you want to lean out your AFR. (Nobody likes a fat bitch that guzzles everything...don't be that car...)
REMEMBER: START SMALL. ITS EASIER AND CAUSES LESS POSSIBILITY FOR ENGINE PROBLEMS.
Ok. Lets adjust your Fuel MAP.
Click on the F, Fuel Maps:
First thing is first. We've got to scale our Fuel MAP just like we scaled our Ignition Map. Only different is, the Fuel MAP won't let you tune below 4000 RPMs and its other axis reads in PSIA or MAF Volts. For my purposes, I used PSIA. (You'll get your cars personal PSIA from your datalog...looked at the lowest value PSIA when you were at 99 % + TPS...that is the PSIA you need to tune for. Ontop of that, if your vehicle is like mine...and a few others I've talked to...you start running rich around 4500 + RPMs).
My personal scaling for RPMs on the Fuel MAP is:
4300 4400 4500 4600 4700 4800 5000 5100 5200 5300 5400 5500 5600 5700 5800 5900 6000 6100 6200 6300 6400
My personal scaling for the PSIA is:
16.4
16.2
16
15.8
15.6
15.4
15.2
15
14.8
14.6
14.4
14.2
14
13.8
13.6
13.2
13
If you notice...I've got a little past and behind where I need to tune. This will help prevent any issues with the FIC reading.
You may have asked, what issues...the issues I ran into my young Padawans: The FIC can only read what you tell it. So lets say you have a value entered on every value box with my scaling. When your cruising at 2000 RPMs on the highway at 10 PSIA the FIC will understand that it isn't at 4300 RPMs and 13 PSIA so it will read the lowest value box it possibly can...which would be the value entered in the 13 PSIA and 4300 RPM box. Now, lets say you've entered a -10 in that box. You're telling the FIC to pull 10% fuel at 13 PSIA and 4300 RPMs. Which is fine...but since the FIC doesn't have any scaling below that it will assume that it is supposed to pull 10% for anything below the listed values as well...causing cylinder misfires, idling issues, fueling issues...all sorts of fun. So how do you get around that? Simple. The first breakpoint axis values always stay zero'd out. Tune after that and you'll be good to go. My Fuel MAP reads 0s in every value at 13 PSIA and at every value under 4300 RPMs. Now, the FIC will rest at a 0/stock value until I reach 13.2 PSIA and 4500 RPMs. At that point the ECU and FIC will start working together and start pulling out whatever percent fuel I have entered. Understand?
Now, you've got your datalog. (Have you decided how lean you want it to run? I've heard/seen guys running from 12.5 up to about 13.4. Your call...your car. You may say 12.8 get it there and want to see what she'll do at 13. Trial and error process.) Pay attention to your AFR. You'll be pull fuel where it dips below what you want it at and adding fuel where it runs above what you want it at.
**Note: If your TCL Light and the car with the swervy lanes come on...I can almost guarantee you've just thrown a cylinder misfire code. You'll need to ADD fuel into the MAP wherever you just ran too lean.
Ok...you've got your datalog...you've got your AFR...if you right click on a certain RPM breakpoint value...like 5500 RPMs, the entire column will light up in blue. I say right click because now you have the + and - function visible. If you need to run lean...- out some fuel. If you need to run fatter...+ in some fuel.
Generally speaking...you'll pull less fuel on the lower RPM ranges than the higher RPM ranges.
You're now gonna pull fuel...go for a datalog session...rinse, repeat. You throw a misfire? Add fuel and then go for a datalog session...
