I am looking for info on these adjusters. Is the stock timing 10* at WOT or is that base timing? More importantly does the adjuster change the timing across the rpm range? I have the Predator but it only changes the timing at WOT. Is 14* the amount of timing that the 4.6 responds best to on pump gasoline? The Steeda site has an icon to find out more info on their adjuster but I cannot access it with this webTV system I use to access the net. Midle aged and computer iliterate!
I am dissapointed as to what info I can acces with the Predator. Can't access the Gas Acceleration wot data group which contains the info that a dyno would use for tuning! thats what I want to see! There is a possibility the stock tune will access that info. I will try when the roads are not wet as it's raining here in central, NY now unless anyone knows that it will or won't? Thanks, mark

Edit - Anyone besides steeda.com sell steeda timing adjusters or does any other company sell timing adjusters?

only ones ive seen is steeda timing adjusters. else you have to use a tuner to adjust the timing.

Like for ignition timing? Why not just get a tuner. . .

eh i take that back. Tuners arent that precise

I already have the Predator. I read 17 boring pages of FAQS on the Diablo site and founs one question that I also had answered. When I add 10% timing with the tuner I am adding it to the stock timing of my motor which I believe is 10* so all I am adding is 1* for a total of 11*. If that is correct then it's a waste to go from 87 octane to 93 when 93 should and apparently does support 14* and would probaby support the 15.4* that adding 10* to 14* would yield. 10% sounds like a good jump but 10% of what is what we need to know and it seems it's 10% of 10*! Thanks, mark
PS: What I am trying to find out is if the adjusters adjust the timing across the entire rpm range as that would be the most beneficial for both mileage and performance. The Predator's 10% is at WOT only. A custom tune would only modify the timing and AFR's. Having a bit of knowledge would enable a user of a tuner to do his own custom tuning! I sold my wideband when I parted out my turbo Talon as I didn't think I would need it but sure wish I had it now!

Just remember there is no solid advance. Mustang has varable timing. You can have anywhere from 15 to 30' depending on rpms and throttle position.

Yes Ben there are many variables that effect the timing, incuding the rpm's and the TPS plus air volume as read by the MAF, temp of the air, etc. I am simply trying to educate myself with the help of the more experienced members like yourself. How about coolant temps? Does the ECM or ECU(not sure what it's called in Mustangs!) affect the timing. Let me make that clearer. The Talon ECU would pull timing if the coolant temps were too low or too high. It had a range that it had to be in to advance the timing to it's fullest, something like 185*-205*. Anyone know if that is the case with Stangs or is it OK to run a 160* thermostat? Thanks, mark

I have the Steeda TA installed and set at 14 total advance. The stock is 10 degrees. I was under the impression that the timing was not variable, as the '05 and later are.

Some tuners allow you to adjust timing across the curve to keep a/f safe. The TA is fixed.

BTW, although Steeda recommends 93 with 14 degrees, I run 89 and have never had an issue. I recommend them.

To answer your first question, I think BBK makes a TA also.

I was just reading something earlier that recommends against 160 stats. THe article was in Modified Mustangs and they recommended keeping it stock. However, I know several folks running 180s without any issues.

Mac makes or used to make a junky one that kinda worked

bbk makes timing adjuster but it costs more
