Its a 195 degree thermostat, have considered it could be acting weird and may change it. The radiator is an aluminum aftermarket from Overland Performance, made for the ls swaps in jk's, pretty sure...

Correct, this isn't the coloado log, didn't have one and not going back just to get one. This one I thought hit 212 at one point on a long grade at roughly 80mph with the air on but shouldn't have...

I've got a 2010 Jeep JKU with a Motech gen 4- 5.3 v-8 swap. The Jeep seems to want to get hot (235) and it lacks power only when climbing mountains in Colorado on a yearly trip.
No other...

Yes, I believe that is it, sounds like that is normal just want to make sure.

I have stated looking at tuning again as last week I had this 2010 JKU wrangler with a 2012 suburban 5.3/6l80 out in...

Yes sir, I suspected that was the case but still get uneasy seeing it go to 2.00. based on how this log looks would it be good enough to leave alone or can it get better or much better?
thanks

I am still learning and getting close on my gen 4 -5.3 fuel tuning but I have noticed some sharp lean spikes when getting on the throttle hard. Can anyone give me some clues as to what is happening...

Hello, I could you some help. I have a 2010 Jeep with a 5.3 and 6l80 motech swap that has been done almost 3 years and that had a stock 2013 suburban converter and my manual mode with tap shift...

I think I have everything dialed in, fuel trims seem to be in check but whenever I let off the throttle, she goes rich for a bit. I'm not sure if I should ignore it at this point and roll on or is...

I guess I should add its a 2013 gen4 5.3L LMG.

What is weird is that I have not changed anything and 2 weeks ago this was never a thing, it has always started, idled and warmed up nicely.
Can someone take a look at the log and give me an idea as...

Dang, having no luck getting the log file to upload, sorry about that.

No sir, I know the dash info is off, I ignore that. I use an app on my phone called "acar" that I track fill ups and miles traveled, I'm pretty sure it is accurate. I have the proper size tires...

I have a 2013 gen4-5.3 and 6L80 from a suburban swapped into my 2010 Jeep Wrangler. I have put on over 15000 miles since the swap and using the basic tune from John at Overland Perfromance and I have...

Dammit, forgot to copy it to the other table. And Lakegoat, you were correct, 20 was to much, she is rich now. I think I'm back on track now.

I did go back before last write and set:

all three dtc"s to mil on first P0101,102,103
Set DFCO Enable RPM to 8000rpm Disable to 7999. GRG shows doing this in one video but not the other for...

To be honest, it took longer to tune the MAF because I am new to all of this. I adjusted incorrectly several times, added or removed fuel when I should have done opposite. In the end I did understand...

I don't believe I have a leak but could smoke it again. I had this thing professionally tuned and got screwed, that guy didn't notice a leak but that doesn't count for much I guess. I bought my own...

Rookie here and could use some guidance. I spent a few days tuning the MAF and I got it dialed in perfectly and now I have moved on to VE tuning. This is a 2013 5.3 with DOD removed and a stock...

About to buy the AEM 30-0334 X series wideband and need to know if I have to have the pro features to use it? I already own the MPVI2, just need a wideband to tune my ls swapped Jeep. I have no...

I did change several things.
I removed 5% on the MAF curve as you suggested

Based on a couple other comments
I changed the power enrich delay rpm to 5000 from 100
changed the power enrich eq...

Thank you for the replies. I did go out today and did some logging and came up with a much better file.

No, it is a new one that came with the swap kit. I see lots of things that are different than the original file but I just don't have the knowlege to put it all together and understand how to make...

Thank you for the reply, this is a Motech style swap sold through Overland Performance. It did log more info before the tune so I was curious if he had disabled the O2's?

The Jeep has 4.10's and...

I am new to hp tuners and have a lot to learn but do enjoy learning although it's tougher in my mid 50's. :confused: I have a 2010 Jeep Wrangler with a 2013 LMG 5.3/6l80 that I recently had...

Hello, looking for some guidance on engine/trans braking. I have a 2013 5.3 (LMG) and 6l80 swapped into my 2010 Jeep wrangler (motech style kit) and for the most part, I'm pretty happy with it....
