Good question, I'd also be interested to know.

Nope they don't. The 03' Cobra values and Lightning value files are set up for 1.99 load.

Also, on that 93' Cobra, what is you calibration code? I'd like to look at some values to see what the computer is setup from the factory.

Thanks Doug.

x3z

X3Z isn't much different than a9L stuff - 24/24 on injector slopes, diff. MAF transfer curve, injector timing is diff., WOT fuel is slightly richer, timing is slightly softer, 93mph "speed limiter" (pulls a little extra timing and makes a/f slightly richer) - that's the big stuff I can think of right off the bat.

You all are going to force me to pull the laptop out and check a datalog for my load values, now. To be honest, I'm not sure what it was now...

So does that mean the load values go all the way up to 199%? What about the fuel tables, what is their max load variable?

I'm sorry, I said that wrong. The 03' Cobra Value files are set up in the spark tables to goto 1.5 load or 150% load. The fuel tables are in TPS settings so they only goto 650 and I would imagine anything above that is the same as 650 or the multiplier from there. This is for the Cal code YDH1.

Now in my software I have a completely different setup. The injector slopes are very different along with Comp Batt voltages( the values changes for different size injectors). Also the MAF curve has a bit more fuel added to it. The timing at WOT only varries by one degree above 5500 rpm's, everything below is the same @WOT. These are comparing the A9L to the X3Z.

Here's a comparison file from both, file 1 is X3Z and file 2 is A9L...

Thanks, Doug.

interesting files.

93Cobra#2771 · 03-17-2005, 06:13 AM

I don't recall the batt. voltage differences, but you are correct on the MAF transfer curve (93 Cobras had a 70mm MAF). Little confused on the injector slopes though, as the high and low inj. slopes are both 24 (tweecer software), with fuel trims used to control low rpm fuel.

Interesting comparision between the two, however. What software are you using? SCT?

Same here.

Yes he uses SCT

Yeah, I'm an SCT dealer but I dont do many Mustangs or Lightnings. My bread and butter are Ranger's and Explorer's but I do like to jump the fence every once in a while

Still, if you had a MAF calibrated to the injector size and your load values seem off then I would scale engine displacement to just see if it helps.

Are you using the Tweeker software to datalog as well? What kind of values are you able to get with that? My EEC4 tuning is very limited because I cannot get a scan tool that will datalog enough stuff on a EEC4 car to be useful.

THanks, Doug.
