OFT / Rom Raider info needed
First time messing with the OFT. I have searched high and low for info on this site but can't seem to come up with it so here goes.. I made 3 pulls on the dyno Stock tune for a base line and went ahead and loaded the Stg1 map. Made 3 more pulls all is good. I have data logged all the stock runs and stg1 runs to this point.
I now want to start making changes to timing, load, fueling etc. Romraider needs the right Definition files. I did research and using the OFT Def's only seems to be the key. Back in the day is was V2.06 zip folder with everything in it. When I downloaded my Free maps off openflash's site the last file is a V4 .XTL File which is what I am using as the definition file. The Stg1 image opens in rom raider but the real problem that I am having is major power / trq loss from what seems to be load being clipped. If I open the stg1 map in rom raider, make 0 changes and load it back in my OFT and make another pull and it's down 20-30 at the same timing, but load seems off. The first time I loaded through rom raider I made a small timing change after 5600rpm, had the issue and then tried opening the stg1 map with No changes at all as a test and the loss is still there. I keep thinking my Definition file I am using has a glitch or isn't good? I have the latest OFT V4 files. Any direction on which definition file I should be using exactly? I appreciate the input. Something is off & it's driving me wild.

Do you let the ECU re-calibrate after flashing?

I was just about to follow up, it was temp sensitive / re learn. I was letting it idle for 1-2 mins but some pulls were at 172-176F after doing a bunch at 185F-190 all is good. Thanks for the reply. I’m going to go through all the tables Tonight that I didn’t have a chance to go through today. Love the rom raider software / ease of oft.

Download the tune qgqin from oft site flash that without editing see if problem solved if so you likely changed something in romraider by mistake, delete any tune files you edited. Make sure the correct def is in romraider and you only have one def in the list of romraider defs also after flashing male sure you let car idle and check vvt cams are active log cams with oft if they dont move cams not active and it will run base timing A table not vase B as its in low power vvt off mode some cars take a while to activate cams and need bit of driving and a restart and more idle |

@Berserker: also few steps one can take after flashing or disconnecting battery to quicken/shorten "relearning" bits (though not sure how some of steps are applicable if in case of AT though):
- dead pedal fix (relearn throttle pedal travel. IGN:ON (press twice start button w/o clutch pressed), press fuly & release accel pedal few times, then IGN:OFF) - idle rpm learn (start engine, idle 1min w/o doing anything) - drive in 3rd gear at around 2-2.5K rpm at ~ 20% throttle, slight left foot braking if needed to prevent acceleration, to reset IAM to 1? - slowly/steady accelerate 2K-7K in 3rd gear to relearn fuel trims .. or at very least do first two steps as simplest/quickest, and then just drive normally, 2nd & 3rd more or less happening over time of some driving/mileage. |

Thanks for the tips I tune Ford Ecu's on a regular, just a bit different process right after the flash is done on these 86's.

@churchx thanks. I hadn't heard of that dead pedal thing. Thats the sort of thing that all the tuning pros should be telling us in the step by step processes.
