Anyone use this feature? Could this be used to help smoothen out the ECU -> XEDE transition? (ie. ECU timing switching to XEDE timing?)

Maybe my hesitation is coming from the abrupt crossover points in the timing, boost, maf settings....just a thought....

I have tried driving around with a friend while watching the little yellow boxes to try to determine when the hesitation is occuring (load points and RPM) but it only usually happens when I drive alone.


**EDIT: What does this mean:

Adding offsets to timing maps can cause problems when a result
passes through 0, because of the double retard feature.

 

I use it everytime I retune new basemaps from Al. Its a very nifty little feature that really is a nice touch. You can interpolate on either the X or Y axis with multiple columns at the same time which is great as well.

Didn't Shiv tune your maps? If thats the case, I would doubt that you are seeing abrupt enough changes to your mapping to cause hesitation. I use the interpolation to basically smooth the edges to help round off the abrupt changes around the maps as they progress "Northeast" up through load/rpm @ Wot. Another fairly cool thing that I've noticed is that the interpolated values from WOT back down to 0 *tend* to be fairly solid values as far as partial throttle performance goes as well.

 

yeah, he did....its a long story. The map that was once "perfect" is now gone, well, every now and then. It pulls like a raped ape one time, then sometime down the road it hesitates/bucks, etc....only happens under 4300rpms

 

Don't confuse the way the Xede and UTEC work with respect to timing. With the Xede, it's always "ECU timing". The Xede is not firing the coils directly... it tricks the ECU into firing at a different time by modifying the crank angle sensor signal. AFAIK, the CAS signal is always replicated by the Xede, so there is no "transition".



Where is that from?

 

yeah, thats true, its always the stock ECU timing.....so you should never have a hesitaion caused transitions then right? Whether its from timing, MAP, MAF, etc....

Under the help tab in XMap2....then click about.....then issues in the lower right hand corner..


I remember reading on nasioc.com when Shiv commented on the drivability of both the XEDE and Ecutek.....when he switches from car to car, he cant tell which one has the XEDE...Because of this "problem" on my car, I was thinking of switching to Ecutek to get rid of this poor drivability. Maybe my XEDE is bad
