OVTune 3.5L Tacoma Supercharger and Twin Turbo Systems

@OVTune,

FYI Emailed you yesterday (#22272) with new data logs for TT tune.

It's been 3 weeks but finally got around to fixing my oil catch can vacuum leak. No more issues with cold starts and idling.

However, still having timing issues under full throttle but I'm only running map#2. Boost gauge stays around 7-8 psi with occasional spikes to 9-10 psi with full throttle. I'm running URD Y pipe with 3" MRBP exhaust. Do you think there is not enough back pressure in the exhaust that could create tuning issues?

 

Looking forward to both the new tune and the controller

 

@OVTune I just sent you an email, my overboosting is due to my driver side wastegate being stuck.

 

Did some towing today for the first time. About 3500 pounds for 100 miles or so, ran good, nice and strong. Shifted well, ect is still desirable when towing to hold gears a little longer.

Hit a steep incline on-ramp from 25 to 70 or so, 5 psi pretty much the whole run, got that smell back of first time heat shield adhesive melt, probably the hardest I’ve run them so far so it was expected I guess.

Looking forward to no codes though, can’t wait for that new tune. Is there an expectation of release?

 

Sorry guys I'm pretty sick at the moment. Will resume, just need a few days

 

Copy. Will be towing over the next week or so. Runs good, any use for logging while towing, or just stand down and wait?

 

Please log as much as you'd like. Data is helpful

 

Get well soon!

 

Tomorrow will be the one year anniversary of paying the deposit on the turbo kit. 11 months since paying the remaining balance.

When are these shipping?!

 

I don't know but I'm ready for some boost

 

I have a 5000lb tow test this afternoon, which is the final test of our newest tune (and final update) then we are all done with everything and move to shipping again.

 

Assuming the tune performs well during your test, does that mean that the updated tune will then be rolled out to existing kit owners?

@Turd Hawg

 

yes

 

Any videos?

 

it's been 1.5 hours since he made that post. it's barely the afternoon. jesus. you guys are insane / bored as fuck.

 

I could make a video however I really don't know what to video. driving down the road? I'm just doing it to verify driving, fuel, afr, etc is all good to go

 

Tow complete.
Took a video + logged the entire thing.
Average MPG was 16 (trucks calculation).
Total weight was roughly 5200lbs.

Drove perfectly. I have a video going up a good size hill, truck never went above 2500 rpm.

I recall towing a few years ago with less weight and the engine screaming at 4500rpm for a majority of the drive.

This time nearly the entire drive was in 5th at 65mph. Just be prepared to be in boost the entire drive.


Only 1 thing felt sketchy: the brakes. This truck doesn't stop 5000+lbs very well like a tundra does.

 

It doesn't stop very well while towing nothing!!

 

Check out @crashnburn80 brake upgrade thread https://www.tacomaworld.com/threads/brake-upgrade-stoptech-rotors-trd-performance-pads.523829/

I did this plus SS brake lines and it makes a huge difference

 

Uh huh. Username checks out.
