UCON Flex Advanced Engine Management System

Well, do it all yourself and buy new. My only cents.

 

Such is life when you're dealing with an older design non-TVS blower.

 

Ok I see now. So I did a total of 5 samples earlier. 2 of the 5 show the missfires all the way and the other 3 are all zeros.

 

I will check the pump for sure. Thank you. The only reason I was thinking it was Ucon related is because as soon as I installed the Ucon is when I noticed it. So just always figured it was the learning of the it. But it is still there if I change my driving style. And I can't drive normal long enough to see if it goes away after a bit. Also thought I should ask in case someone knew that it was the Ucon guardian kicking in. If so, I need to see why it is kicking in.

 

I missed that the Ucon was a new addition....you logic sounds right. I'd reach out to Gadet and get that looked at.

I think my pump failure experience has me always thinking about it first. Starting to sound like Bob Barker reminding you to spay/neuter your pets or your news channel reminding you it's time for a buddy check. I'm just hear to spread awareness!

 

One reason I love the TRD reflash so much. No codes How is the haltech 2500 working out @Torspd

 

Brilliantly. Love it, and no turning back. Can even tune the VVT-I better than factory .

 

Just wanted to report back after a couple runs datalogging. Truck has started to lean out a few points after a bit of learning and looking at the graph AFR commands are pretty much like @Roostfactor as per air load and Maf(g/s). Notice at 177.8 load my Afr command is 11.22
I think Scott either mistyped the 10.2 at 150 air load or was prolly still drunk that morning when he answered my email, that's all.

Something to note at about 340ish g/s my Max IDC on 840cc injectors are at 62 percent capacity. Still plenty of headroom left.
347 g/s was the highest I've seen that evening within a few runs. Looks like at nearly 4000 feet I'm only equal to or under most running the 2.55" pulley. Will see again once the 76mm throttle gets install along with a more aggressive porting.

 

When you have a rotrex and it goes, yes poverty is the proper word to use. In my case I had a C38-91. I opted not to spend 4k CDN to replace it, I then decided not to even rebuild it. There were two companies that were known to rebuild rotrexs', although it is not recommended by Rotrex themselves due to the tight tolerances, they claim it will fail in a short period of time. With that in mind, I decided to try something different. Ended up buying a TRD system used locally and sold the rotrex kit. Sold it with my old indestructible c30-94 that I over spun about 10-15 percent using a 70mm pulley for 4 years. the last 1000-1300 RPM is where the rotrex really shines over my current TRD setup.

 

Why do you have to be talking smack about my truck?

 

Haha, technically talking smack about most all of our trucks!

If you're on this thread, it's too late. You've got a hole in your wallet.

 

Ha! That I know, but F/I is more rewarding than hookers and blow.

I saw those words "Poverty Charger" and lightheartedly took it to mean you were calling out my truck (check my vehicle descriptions).

 

I think you are higher than most considering your elevation. Hard to tell though because of the temperature advantage you currently have.

 

I’ve noticed in higher elevation that Barometer pressure has a huge impact regardless of temperature for FI. Just sayin

I need to look back at my ucon data logs and see my MAF g/s

 

In the midst of winter, the truck feels like a rocket ship, with all 4 wheels spinning, drifting sideways from light to light, like it's propelled by a set of jet engines. I am not sure if it's the -30 degrees Celsius temps causing huge power gains or if it's the illusion of it due to lack of traction in this winter wonderland I call home. When summer comes around its slow as balls again.

 

Maybe a bit of both but today it was 60°F and the truck was sooo responsive. It almost felt like it was supercharged or something.

 

How long (in miles) is everyone in here with the TRD/Maggy S/C letting the UCON relearn everything after resetting the battery for more than 3mins (IE resetting the UCON)? Scott had mentioned I need to drive normally for at least 50 miles to let it learn everything before romping on it. I drove mine for about 100miles the other day before getting on it and it still is stuttering in 3rd gear at 3k rpms at WOT (guardian is kicking in from it running lean).

 

As soon as it was installed, we romped full throttle to 90 within the first mile, I guess mine figured it out ok, lol.

 

Advanced learner.

 

Yep, been working it hard since the day the Ucon was put it. Made a world of difference in how smooth and responsive the truck was.
