Hey guys, new to the tuning world, but im learning, just did my AFM and it took me a little but i found it (actually called DOD) I was wondering about adding a bit more throttle response to it. Right now the truck feels sluggish or takes a couple seconds to feel the horse. I dont do any racing but i would like to make the truck feel responsive. Do you recommend any videos or tuts on this? Maybe a file i could use to compare? Anything helps! Truck is completely stock besides small mods like an oil catch can and muffler delete. Im a little hesitant to just messing with stuff because im very new to this and dont wanna mess anything up especially since its my daily. Thanks in advance!

I'm working away on my Defender 110 with L83 swap and it seems to be running pretty good now but I can't get the fan to power up. I had it idling in my garage trying to get the temps up but I got to 107 C and shut it down. In my desired ECT graph I have 106 C where I expected it to come on. I can't get it to run using the VCM Vehicle Controller on VCM scanner either. I tried PWM EV and PWM Electric as well as 100HZ and 128HZ in all the configurations possible. I only have the power and ground as well as the green wire going to the ECM, I don't think I need a controller do I? I'll double check which pin I used on the ECM. Any help would be great, and yes I am very new to this and I've watched enough videos to be dangerous. Thanks, Sean

I just had to buy a new laptop and transferred off my old one and reinstalled the software, and it made me resync before it would save changes to the file I downloaded off the truck ... IT LET ME SAVE CHANGES!!! I went to write to the truck and it says I don't have credits ... I have 8 and it won't see them ... I hit resync 50 times!!!! What do I do???

Hey forum. Im trying to help a friend to solve an issue with his project car. Somebody else put the drivetrain together. Vehicle is an 80ish C10 truck. Gen IV Aluminum block 6.0 with a BD 2650 kit with FID 1000cc injectors. Custom CAI and headman long tube headers Unknown aftermarket cam 6L90e It has a PSI harness with E38 and T43 and it have been runing for some time. The problem the engine is having, whenever gets to operating temp, it cranks, fire and runs for a couple seconds, then die. No matter what you do (from a little gas pedal to floor it) it won`t stay running. Its getting a pretty similar VATS behavior ONLY when its hot (lets say above 197f ECT). Some additonal notes: Whenever the engine is cold, it will work perfect. If you let it sit for some time (lets say 5-10 minutes) it will crank and run normal. I`ve checking and adjusting some parameters and weird thing is, whenever you do a "write calibration" it will crank and run normal. It may be because of the wait time. Somebody else replaced the ECM with a new unit and did a OEM flash and then transfered the calibration strategy and data. Same result. He has an AEM wideband and its confirming the lack of fuel in the exhaust stream. Cranks and for that couple seconds goes stoich, then lean! I`ve seen that the injector and some other data is wrong but as long as the vehicle is able to maintain that post 3 seconds after crank, it runs good and fair for him, so I`m just trying to help him solve said issue if possible. I

I purchased the mpvi4 upgrade and AI seems to be just confusing for trying to get a straight answer as to what i need to provide so my old mpvi i'm sending back doesn't get stuck at the border or sent back to me. Does anyone have some solid info on doing this without running into issues? Should i use Canada Post since they deal direct with USPS? Are there forms that need to be included?

So you always hear about these guys taking their vehicle to get it tuned.. Today i finally learned what that means. If it will crank up and drive then its "tuned".. Take this for example. 6.2L GPI 4SS cam LS3 Injectors Non vac ref regualtor 4L60 3000 stall 4.10 gears 29.5" tire Guy complained it would run for a little while then start missing and would foul the plugs in less than 100 miles. The "tooner" showed up to his garage and charged him $500 to load this locked toon. Attached Files LQ LeeSmith.hpt (224.8 KB)

This is my first post here, been lurking for years, but my other account wouldnt let me post. I have a heads cam LS1 that will usaly stall after a quick rev or when coming to a stop and i clutch in, details posted below as well as some recent idle/rev logs and the lasts tune. The tune is a mess, im franticly trying this to resolve this stalling. 11.5:1 SBE LS1, PRC heads modified and customer 231/239 114+3 .645" hyd roller cam from Tony Mamo. Fast 92 intake and Fast 92 TB that ive opened up the inlet and exit of the IAC. Im running a 10lb alum flywheel and Mcleod RXT clutch, aprox 38lbs for clutch and fly wheel. Ive slowed down follower decay, ive play with over and underspeed ignition. Im not totally clear on adaptive idle PID, but ive reduced all the high tables. ive read hanfuls of threads on here and ls1 tech, and just cant seem to get it to drop down to idle after a quick rev. Ill upload the stock calibration as well and a few idle logs, but in sure i will be mising some channels. Im at the point where i need some experianced help and fine with paying to have it resolved. Thanks for all those who reply.

https://www.hptuners.com/vehicles/ford-tuning/ Says '13 is, but no clear listing about '14 3.7. Specifically I'm looking into converting CNG vehicles and vice versa - with supporting calibration. Thanks

Got a LS swap in to sort out some issues. Most everything is fixed but ive run into this problem where the PCM stays powered up and i can communicate with it with no voltage on Blue 19. Battery drain issues from PCM drawing 1.1 amp on Blue 20/57 combined. I stumbled on this because TPS was showing 11.5% and not being able to do a TPS relearn. Never seen such so confused right now. Got another PCM to try in the truck here shortly to see what it does.

need help on a 2003 lm7 5.3 with sheet metal intake got it running.

I just wrote a tune for my trans and when I go to reset adaptives, my status at the bottom shows nothing.i clicked on adaptive reset but did it do anything? How do you know. The trans seemed to shift ok when I drove it but it would not do anything when I hit the buttons. Also fast learn did not work. Temp was up and I didn?t have any notice. Just trying to understand as I may have another change to do.

I am getting mixed reviews so I need clairification. It is a 2015 camaro ls3 with a lsa swap, zl1 fuel pump and returnless. When adding the DW 1000cc data it maxes out at 508 kpa pressure delta of 127lbs. Can I run the data maxed ate 127lbs from 508kpa and up or do I need to half the IFR and double the Stoich? In reality will the car ever see 500kpa or above delta? And if I have to scale do i only modify IFR and Stoich tables only? Thanks
