Tacoma - OVTUNE - VFTUNER - Update Info and Original Development

I think you are asking How to clear dtc?
Flip the truck go on
Hit the clear DTC button

you can also disconnect the battery and try again after connecting

 

I tried that. See photo. It says that it completed successfully, but the CEL is still on and DTC is still there when I click Read DTC

 

Did you flip it off after clearing?

 

You could also try with techstream

 

Yeah I turned it off. Guess I’ll try TS

 

Maybe there's an actual issue that's causing the code to come back right away?

 

I had this code come up after reset and it ended up being chewed wires at that sensor. Had to remove the intake manifold to fix it properly.

OP check under your intake manifold just in case

 

Yeah if it's Staying on it's a hard code. If you can, try to do research on code setting criteria for that exact code, it'll help narrow things down. Or try the stock tune and see if anything changes

 

If it matters....on this current tune I'm also getting crazy misfires for the first 5 mins of driving. No MIL though.

 

I have as well, and let Mat know.

 

Thanks for the advise gentleman. I’m gonna start another thread so this one doesn’t get any more cluttered

 

For !@&$’s sake this threads already a mess and you guys are cool so I’ll provide an update and ask for some advise...

I popped the hood and sure as shit, there’s rodent prints everywhere and I found some chewed up wire. Is it bad to drive the truck without a camshaft sensor A on bank 2 till I can fix it tomorrow after work?

 

Wow, good call, Sosk!

 

Under your plastic engine cover there is absorbent material. Load it with peppermint oil every 2-3 months and your rodent problem will be a thing of the past.

 

I couldn't take it anymore. i thought maybe it was in my head that my truck wasn't running all that great on the newest tune 04B04+2.0+Base+91+OL+31+-+33T but after 1000 miles I went back to 04B04+-+2.0+EROM+91+-+Shift+Build+19800. it runs much smoother now but then I lost the improvements of the newer tune. I hope the re-release or final release clears up the stumble start and whatever other problems the original culprit causes. @OVTune are we going to retest 04B04 again before 2.0 final?

 

what improvements did you see with the new one that you didn't on 19800

 

Better all around shifting (better use of the TC to smooth it out) & Performance mode on ECT (I run 93 octane) to name a couple. One thing I do notice on the older tune is that it will climb long hills better with out having to downshift. But when it does downshift ugh, the old hard downshift into too many rpms.

 

That was by big complaint about the last version, and it made me have to temporarily revert to stock. What it was doing in my truck was completely skipping 4th gear for downshifts at highway speeds. The most common scenario was on the long hills that we have on I-91, it would try to hold 5th way too long, and instead of jumping down to 4th gear when it couldn't maintain speed it would jump to 3rd and the RPMs would skyrocket.

Personally, living in a hilly area and towing from time to time, I'd rather it not lug the engine in 5th and just use 4th where needed like the current beta (and the stock tune) does for me. But I understand that's subjective and not everyone agrees.

 

thx.

still waiting to test the final 2.x. Still on 1.05/93 perf. w/ zero issues so I have no reason to change it. The ONLY thing I'd like to do, if I decide to play around with vF tuner is to adjust the tip-in a bit so there's more of it. ECT button causes a bit more tip-in which I like so I use it often. If I could make this tune run like ECT was always on it would be perfect.

 

any Nuggets gettin a tinglin for this weekend?
