I just installed my RC 550's (saturated) and a walbro 190lph I haven't installed the turbo yet, but decided to get the fuel system installed and straightened out first. I'm running on uberdata v1.2 and had it running perfect on uberdata on the stock injectors and pump. Basically stock map with a little extra timing up top (93 octane only), rev limit raised to 8500, stutter box, and little higher idle.

That said, we switched in the 550's and pump, scaled the fuel maps and forgot to change TPS enrichment So the car felt like junk, once we realized and changed to 55% the initial on-throttle hesitation is gone, but at random highway partial throttles it hesitates and jumps around.

Any uberdata gurus have suggestions? I am going to try to lower the TPS enrichment a little more, but I'd rather not just be shooting around in the dark.

Do you have a wideband o2? Sounds like it might be a little lean under some conditions.

 

why are you using verson 1.2?

there is a version 1.65 with a injector calculator that will re-map your whole fuel map and select the best TPS enrichment for your injectors.

download it here: http://www.ecimulti.org/uberdata/

 

My friend with the burner likes 1.2 the best, but ya, I figured using a new version would take care of it. There are some options in 1.2 that didn't seem to be available in the newer versions which is why he likes 1.2

 

I wasn't aware that there was 1.65, only 1.63.

I just instaled 1.65... it's badass. Well done Blake.

On the other hand, I am not a huge fan of it selecting everything for me, so I may end up tweaking it regardless. Looks great though.

 

i thought so too at first but once you start using 1.65 you will like it much better.

the 2d map view is much better because you can grab each cell with your mouse pointer and smoothen the line. in ver 1.2 you cant do that.

besides......the only thing version 1.2 has more that 1.65 is a IACV adjuster.....

 

No, I agree 100%. I only had up to 1.60 or 1.63, which was teh suck.

1.65 is freaking cool. I will be playing with it tonight, for sure.
