I bought new FIC injectors last month, November, for my FJ installed it and found out it doesn't work with my Ucon. I knew it was for the Tacoma but thought it's the same engine (2007-2009) and hoped it would be ready down the road when it became more main stream, but.

What I read over at TW and here on the HPtuner thread got me excited to the point I rushed out and bought one 6 months ago. So far, for us that OS calibration file is for a naturally aspirated 2008, calibration ID 33555100. So with that, the answer is yes, HP tuners have to crack the code. The tuner I’m working with just swapped that out for an newer Evo 7 ecu, which adds faster processing and many more options and flexibility Obviously, the Toyota system is much more convoluted.Ĭlick to expand.My understanding of the tuning process is very limited, it's baby steps, no check that, I'm barely crawling. This tuning is much different than what I’ve been used to I have a ’99 Eclipse turbo which had a DSMLink - a modified ecu where I could change different parameters at will. Does HPtuners build a stock base tune for that, and one for supercharged, based on the TRD reflash? Right now, my truck is stock- no supercharger. So, for me to be able to change any parameters HPtuners has to unlock this specific ECU, correct? The supercharger calibration ID would be 3YWK0400. I have a 2007 FJ AT 4WD- so, according the the TRD supercharger instructions, the calibration ID is 33545000. Apparently I did not understand the bigger picture, so just to confirm: Toyota ECUs all have different part numbers, target calibration IDs, and encryption codes, and HPtuners has to crack each one open to make them accessible.
