I?m considering putting high flow cats back I to my cammed LQ9 exhaust for the unburnt fuel smell at idle. Do I need to turn rear O2s back on or should I be ok just to put the cats in and run with it?

Just trying to clean the truck up some and basically make it run more efficient. Not necessarily looking for a ton more power but at this point looking to get better fuel economy. Do need the...

My 05 Excursion has recently started throwing codes for pedal position correlation....BUT there does not seem to be any dead spots in the pedal. It hasn't stuck at idle or really done anything weird....

My 2005 6.0 had been tuned in the past with SCT, when it was still able to disable the EGR. My system is intact and I have checked to make sure it is clean and functional. When I switched to HP for...

Ok, so I've narrowed down the cruise surge I get under a very specific condition, but I'm not quite sure how to correct it.
Conditions are:
Torque Source: Cruise
steady speed any speeds between...

Ok I?ll start there and see how that goes.
With that being said, is that contributing or causing the surge?

You are basically telling the ECM there is more air and to add fuel. VE AND MAF tables. It isn?t as simple as just adding it in. You can just flat add in 8% across the board but that would be the...

Guys, this place has been super helpful in getting a newb to tune his truck. I still seem to be missing something on this tune though. LQ4/9, TSP Stage 3 LL cam. The guys at TSP told me with this...

Guys I can't figure this out. A few weeks after tuning my F-150 5.0, I noticed a steady speed surge at cruise, with or without the cruise control. It is noticeable but barely. No codes, but when it...

Guys I used a repository tune as a basis for my truck tune. A lot of it is tweaking shift points and transmission behavior. I?m having a small issue and I can?t figure out where to adjust to make it...

No codes at all. Runs great otherwise, just doesn’t want to start as easily when warm. But it is kinda picky and random and sometimes, on rare occasion acts the same way first thing in the morning....

So I?ve been learning and tweaking the tuning on my LQ4/9. It has a TSP stage 3 low lift and other mods. It cold starts good but after driving somewhere and shutting it down it requires a little...

Was the Excursion platform ever offered with a 3.40:1 rear end? I?m fairly certain it was only offered with a 3.73:1 but when I read my stock file, it shows the final drive ratio at 3.40:1. Anyone...

I need to buy a dedicated tuning/automotive only laptop. Having to share my kid?s laptop for me tuning isn?t working anymore! I?m thinking I don?t want a full sized laptop maybe something smaller...

Guys I?ve been chasing my tail forever on this truck. I thought we had a good tune going. Tuned VE then MAF. Now I will say this. A few times during MAF tuning, sometimes it would run lean and...

Yup, I didn't know that when I read the vehicle. But now I'm just that much wiser...:)

I had to remove the FICM from the list of controllers under EDIT/CALIBRATION DETAILS

FINAL UPDATE. Put a charger on BOTH batteries. Made sure they were FULLLLLLLLLYYYYYYY charged and left them on the batteries at 10 amp charge. The tunes then wrote without issue. These Black Oak...

When I pulled fuses and relays and initially got the entire tuned file to write to the ECM, I got a PATs error code and no-start. I have FORSCAN but I could not get it to reset PATS and it wouldn’t...

Yes it has always been able to do that. I’m taking the stock ECM file and tuning that one in stages. I had previously taken the stock file, made a change, saved that revision and then made more...

Disregard all that. I ended up with a no start and am having to go back to square one.....

So I’ve taken every fuse and relay related the fuel pump, FICM, glow plug. Unplugged the glow plug controller and EGR. Battery on charger and the ECM finally took it the second time I attempted to...

I haven’t had a free minute to try it but I am going to Monday. I’ll throw a charger on it and pull the fuel pump and glow plug controller relays and see how that works. I just know the GP controller...

Guys I?m having issues writing a tuned file to my 05 Excursion. It stops part of the way thru with error ?writer transfer x7f negative?. This caused a no-start/turn over it I was able to get the...

Ok, on a slightly different note, is Unl 88/E15 considered a flex fuel? I’m wondering if that is enough ethanol blend to require the same conversion or not.
