I have a question for the Predator users. I have a 2003 Lightning that has a stock 90mm MAF and when I look at the list of stock tunes that come with the Predator, I'm more confused that ever. Here is their list of tunes below. On the bottom of the list it tells you that only the 99-00 Lightnings are supposed to use the 90mm MAF tune. Is that a typo? Does anybody know for sure what tune I should use on my 03 no pulley truck?


This Predator is provided with the Following tunes pre-installed:

87 octane: tune for 87 octane and stock pulley.
Pulley 87 octane: tune for 87 octane and pulley, max 13-14psi.
90mm MAF 87 octane: tune for 87 octane, calibrated for a stock 90mm Lightning Mass air meter, will only work with a STOCK 90mm Lightning MAF.
Pulley 90mm MAF 87 octane: tune for 87 octane, pulley (max 13-14psi), calibrated for a stock 90mm Lightning mass air meter, will only work with a STOCK 90mm Lightning MAF.
91 octane: tune for 91 octane and stock pulley.
Pulley 91 octane: tune for 91 octane and pulley, max 13-14psi.
90mm MAF 91octane: tune for 91 octane, calibrated for a stock 90mm Lightning Mass air meter, will only work with a STOCK 90mm Lightning MAF.
Pulley 90mm MAF 91 octane: tune for 93 octane, pulley (max 13-14psi), calibrated for a stock 90mm Lightning mass air meter, will only work with a STOCK 90mm Lightning MAF.
93 octane: tune for 93 octane and stock pulley.
Pulley 93 octane: tune for 93 octane and pulley, max 13-14psi.
90mm MAF 93 octane: tune for 93 octane, calibrated for a stock 90mm Lightning Mass air meter, will only work with a STOCK 90mm Lightning MAF.
Pulley 90mm MAF 93 octane: tune for 93 octane, pulley (max 13-14psi), calibrated for a stock 90mm Lightning mass air meter, will only work with a STOCK 90mm Lightning MAF.
Factory hp tune: Factory tune, use this to modify adjustable parameters.
Factory hp tune 90mm MAF: Factory tune calibrated for a STOCK 90mm Lightning Mass air meter, use this to modify adjustable parameters.


Note: The 90mm tunes are only available for 99-00 Lightning models as they came with the smaller MAF.

 

Since you have an 03 Lightning with a stock crank pulley and live in California, you should be using the 91 octane tune for the stock pulley. All 01-04 Lightnings have 90mm mass air sensors so just disreguard any of the tunes for 90mm. They are for the 99-2000 Lightnings that have been converted from 80 to 90 mm.

 

If that's the case, what are owners of stock 99-00 Lightnings supposed to do? My guess is it's a typo and should have read 80mm MAF, as they have to have a tune for those year Lightnings that didn't change to a 90mm MAF.

 

If you have a Predator tune in your truck, what tune are you using?

 

I'm using the 93 octane pulley tune in my truck.

 

A company like that does not make a "Typo" on something as simple as a menu screen. Think about it, have you ever wrote a program befor? It is not like writeing a book, if you make a mistake, things go wrong, and they lose money. They would not allows a "typo" on the menu that could confuse a consumer, and take the chance of damageing something. So like I said on the other forum...

The Predator does not mod the stock paramiters in teh ecm in regards to the MAF unless you select the 90mm MAF tune, witch is for 99-00 years only.

 

Then how do you explain on page 10 of their Ford SVT Supercharged Predator manual where they tell you
"To restore Original Backup go to Performance Tune and then select Original Backup. This will restore the original backup and reset the tool so it can be used on another vehicles."
I tried following that advice over and over with no luck. It was only after going on the forums and asking how to restore the original backup was I informed that what I read in my Predator manual was actually incorrect, that I really needed to go to Options Menu, then Troubleshooting, and then choose Restore Original Backup.
I guess since I found inaccurate information in their manual before and then read
" Note: The 90mm tunes are only available for 99-00 Lightning models as they came with the smaller MAF. " which is obviously either an erroneous statement or was worded wrong since the 99-00 Lightnings' came with an 80mm MAF, I begin to wonder how accurate some of the other advice was. Everyone can make a mistake, and I was just trying to make sure I didn't make one by putting in the wrong tune. Thanks for yours and everyone else's help on this issue. MAT2CH
