Where did you get that information about Predators having global timing?blackfang said:Well the thing with the Predator is they have global timing unlike the SCT products so it is kind of hard to get the timing right. That is one of the reasons why I never got it, but went with SCT. The predators tend to have too richness and when you lean it out it affects load and non adaptive. Plus I rather add 3* of timing only when I need it vice throughout my band.
However I do think you can have a custom tune done and sent to the predator.

ooraceredgt said:i havent got any detonation on the road either. i just need someway to get the timing up a little more or that methanol/water inj kit is worthless
ED Clark and my local tuner who used to be a diablo rep and now an SCT rep. Both said the same thing. Yes a percentage which is global.propellerhead said:Where did you get that information about Predators having global timing?
The Predator adds timing proportionally. It adds a percentage of what the stock timing would be.
propellerhead said:Maybe we are not clear on what global timing means. Go figure out what it means and let me know.
The Predator will let you add or subtract a percentage of timing (not a fixed number of degrees) to the timing in the 2000-4000 RPM range and the 4000-7000 RPM range. Whether that's global timing or not,
That's what I thought 'global timing' meant. Like what mechanical timing adjusters do. You dial in 2* advance and you get an additional 2* at idle, 2* at part throttle, 2* at heavy throttle, 2* at WOT, and so on. You get an additonal 2* no matter what the IAT, LOAD, RPM say.jstreet0204 said:If it will adjust in ranges, then it not what most people refer to as global timing. Global timing usually refers to the "Global spark multiplier" By default it is set to one. Change it to 1.1 and it will globaly advance spark by 10% across all rpm ranges and load levels. 0.9 would retard spark by 10%. If the predator adds in ranges like that, it is either manipulating the spark tables, or maybe the spark_adv_rate function.

jstreet0204 said:Your stock location was in the inlet tube just after the MAF. It is a small black sensor that slides into a rubber grommet. The reason I ask, is the EEC will adjust timing any many variables. One of which is intake temp read by the IAT sensor. If you are cooling the air charger after that sensor, then the EEC does not know it has cooled off and will pull timing. My set up is quite a bit different than yours, but the principle is the same. My IAT sensor has been relocated in the lower intake just under the intercooler. Air charge temp also drives many other functions such as fuel pressure, and a/f ratio, so it is best to make sure you are reading the temps after it is cooled.
