My 2016 C7, I have not done a tune for it yet either. I've rebuilt the motor and port/polished the runners, mild cam, upgraded lifters and rockers, headers, intake. It is N/A and my own tune I made for it back in 2007 and made small changes here and there. My LS2 GTO, when summer comes around, the driving vs winter is night and day. And with 110-115-120 around the corner, I can bet the Ecoboost will not enjoy the high iat's. I notice a huge difference in throttle and overall performance as it goes from 50-60 day temps to 100. the stock intercooler is TINY and doesn't do much for cooling air. Thank you Sirius for the changes you suggested! I will also be applying that as soon as I get some free time as well! And where I'm at in Phoenix, the Intercooler is a MASSIVE must have to cool down the iat. I've been pulling data for Pre-Intercooler and will then gather data Post-Intercooler. I've had the intercooler in a box to install and hope to do the install in the next week or so. Life happened and I've been taking care of my wife as a primary focus after a bad surgery and I am just now getting back to my toys. I am just getting back to this thread, lol. Of course, you can leave that and WOT Start at 200 if you prefer the factory-style of driver demand being referenced full time. Think of it as a way to give the system a chance to anticipate mashing the throttle to 100. This is a personal preference so that there is less delay in calculation and physical control reaction when the pedal is floored suddenly. Forgot that part in the first tune I sent you. Fuel economy when you need it.Įngine -> Torque Management -> Driver DemandĮngine Diag code P0605 set to no error reported. I think they are better suited for spirited driving. Also adjusted modes based on engine loads. It wasn't as difficult as I thought it would be because of the 10 degree EVC set by Ford across the RPM range. But before I bore any of you any further with all the question and thoughts I have regarding this I'm staying optimistic that ill receive some good news and hopefully I made a correctable error.Here's a tune with Optimum Power enabled and tables populated. I did read on the forum you can select operating systems to work off of, that seemed to only come up in GM talk. My next thought is to borrow a used PCM from wrecked police interceptor to write AS-Built data for my vehicle and see if my operating system/filename returns back to FCFE6F6. Hopefully Tuesday ill obtain a fresh inspection sticker then back to the drawing board to correct whatever the hell I got myself into here. I had to wait until we saw temps above 40F for EVAP to run its course. lolīut all my readiness codes have finally passed today. I have a U1041 code Lighting Control Module - Vehicle speed signal missing or incorrect - FORDs pin point test informs you to disregard this code. However, I now have a wrench light in my message center, NO P-code DTCs. If I flash to the original HP tune the car goes back to how it was when I bought it, drives how it did speedometer is accurate. If I flash back to Ford tune and try updating my gear ratio using IDS it will not accept the gear ratio. If I flash to the Modified Ford tune it no longer adjust the speedometer for the 3.73s gears - I tripled check to make sure I changed that parameter however while in editor and doing a comparison it still highlights green indicating there is difference between the two tunes but it is written correct as 3.73, which in term creating harsh drive ability concerns due to load calculation/ speed input error. It gets a bit confusing from here so I'll address the tunes as following:įord tune(what it factory flashed to using IDS)įord modified(me copying what the car was(HP tune) to the Ford tune/new operating system) I went from FCFE6F6 to FCFE9F4, that being said I had to purchase licenses for the car because I lost the ability to write the PCM. Since the update the Filename(as Ford calls it) or Operating system(per HP tuners) has changed. Moving on - I work in a fleet management position and have access to FORD IDS at work so I decided to write to a factory PCM calibration to perform a comparison of what was actually adjusted in the vehicles current state of tune. I re-enabled the corresponding systems installed a set of downstream 02 spacers test drove for readiness codes. I was quickly able to identify the first owner had disabled the Catalyst and 02 monitoring systems. I bought MPVIii, read my vehicles tune - installed credits. The car also, has adjusted shift points and 3.73 final drive gears(axle). I was informed by the second owner at purchase it will NOT pass inspection.Įxhaust was rotted so I replaced cat back, when I was building that exhaust I noticed they had gutted the CATs in the vehicle. I bought a 2006 Mercury Grand Marquis LS 4.6L. I'm hoping to gain some knowledge on the use of HP tuners, along with light shed on the predicament I am in. I am Erik, new to the forum and HP Tuners.
