Tacoma - OVTUNE - VFTUNER - Update Info and Original Development

this is somewhat alarming. I've never ever had an auto stall either (though mine likely would have had I not replaced my CKP before it completely died on me). Perhaps this is something to be considered with the "A" shift settings b/c I can tell you that in my auto something didn't feel quite right with 1st in the way it seemed to kick into gear oddly when cruising and then accelerating at slow speeds so I wonder if this could have something to do with it? Shift C seems to be working really well, its just not as great on MPGs as A for some reason.

 

Hmmm I haven't done the sensor yet because otherwise is very smooth running. I was in s mode too

 

I should try out A... im always chasing those MPGs lol

 

So far with 1.02c A on 91 oct. I have almost 300 mi.
Been in 4 low once and the rest city and hwy miles and it's been very smooth. Hoping it stays this way as I'm very pleased with the power delivery and shifts.

 

Please provide more feedback over the next 100-150 miles. I'm 2WD and no 4-Low, and my driving is about 80% highway, 20% city-ish. For my first 300-350 miles 1.02C-A (91) was GREAT. But then of the next 100 miles the transmission seemed to revert to it's old nasty self. I've only used "D" mode since loading the tune.

 

Will do.... was hoping for it to stay as it is now but have heard others say it changes as well.

 

Did you have the brake depressed at all while you were pressing the gas? I thought I read somewhere that may cause a stall....but I've been known to be wrong

 

no, I for sure didnt have any braking going on. im just about to hook up techstream

 

Ill send the complete file to OV to check out

 

It seems like I saw in another post about someone complaining about stalling on an automatic truck. I think it was the post about the truck smoking on an incline or something.

 

smoking?

I'm think someone mentioned their auto truck stalling in this thread. I don't remember for sure though. All in getting to is that it may not be tune related.

 

I have wheeled the tune many times including 1.02C (A) and have not had it stall. Have done steep climes with large steps and no stall. Last trip to Moab was DP and onion creek with not a stall.

 

BigBob's smoked on a steep incline.

 

I pulled the code, waiting to see what it tells

 

This code was present for another member that had CKP sensor failure. You'll need to replace yours, I'm sure of it.

This would make sense. I still need to buy a sparer sensor.

 

So the failure is intermittent? I've never had any of behavior before. I'll get one....just cause it sounds like a good idea and it's an easy thing to do

 

Very, very easy to do. My truck wasn't and still isn't on the recall list but hot damn if my truck wasn't idling rough as hell and having real issues with timing until I replaced that bad boy. It really was night and day... I still worry sometimes that the CKP is only a piece of the puzzle here but for now it's working out well.

 

update everyone.

We should have the rest of the small amount of pending orders out this week.

Then we should be restocked ETA 15-20 days. I know there has been a lot of people asking.

will be doing 1.03 MT right after SEMA. Sorry for the delay, so much stuff going on at once
