I’ve already talked to a local tuning shop familiar with HP Tuner about using it after I install the blower, and he saw no issue doing so. He has another client planning to supercharging his Tacoma and use HP Tuner, so I figured I’d let them be the guinea pig and see how that goes.

Interesting to see how this compares with the Raptor tune.

Oh! That's great news! What year is your FJ?

It’s an ’07.

Ive been following the Raptor Tune thread, and inquired if it would work with the TRD/Magnesun supercharger- no, because that supercharger isn't available in OZ. And now, it looks like the Raptor tune faucet might be turned off- they are cancelling export to North America.

Well, judging by the part numbers Tacoma and FJ ECUs are different.

I guess you gotta try and be that guinea pig. :)

And we should put some pressure on hptuners too.

I’m not suprised they have different part numbers, but the tuning parameters have to be close to identical- same engine, sensors, etc.

Totally agree, there probably isn't enough interest from them to pull the trigger at the moment.

Tuning it isn't the issue, like you said identical to the Taco. If they don't release their piggyback to unlock our ECM it's never going to happen. Raptor's issue is that there probably 50 different revisions of our ECM which requires a different encryption to unlock. They can't just blanket release one that works for all, the guys at Alientech probably have to crack the code every time someone with a different ECM pops up. I imagine that's one guy sitting behind a computer who got overwhelmed.

If you want a shifting upgrade I think the IPT valve body is a better choice. URD already has tuning the SC sorted, maybe you should just get a UCON?

Are you stating that your tuning shop doesn't need to go through through HPtuners to access the MPV12 unit? If that's the case sign me up. However, I've gone down this rabbit hole or rather, guinea pig hole and know for a fact, at least for my 2008 FJ, that HPtuners MPV12 is not setup for ECM part # 89661-35C81 or Calibration OS: 33555100.

Don't ask me how I know:censored:!!
Now, does anyone want to buy a MPV12 with 4 credits for a Tacoma?:rolleyes:

BITedit claims that they do have some maps available:
Editing calibrations Denso ECUs (89661-xxxxx and MCU NEC 76F0038, 76F0039, 76F0040, 76F0070, 76F0085 inside) of petrol Toyota | Lexus vehicles with petrol normal aspirated 4.0L, 4.3L, 4.6L and 4.7L engines.
The folowing maps are available for editing: spark advance maps for high and low octane fuel, minimal spark advance, spark advance corrections, VVT camshaft position maps, injection enrichment control, injection corrections, throttle valve control, requested torque, and all main sensors conversion curves. DTC mask supported.
This is not much, though.

And you'll have to buy a flasher that would read, write and fix the checksums.

Hey guys, Chad from HP Tuners just sent me an email stating that the calibration file for our FJ's (Calibration OS: 33555100) is now updated.
MERRY XMAS!

Correct me if I'm wrong but this looks like TRD SC Calibration OS. The stock NA Calibration OS for 2007 FJ AT is 33545000.

I'm gonna go cry some, until proven wrong. :)

Also, if that's for stock, can someone post the stock HPT file here?

You might be right, I believe I was referring to stock but didn't realize it was the TRD cal.... I do have a TRD S/C. I was basing this on what JustDSM and HP tuners gave me. I just contacted JustDSM and hopefully he will have more info for me to pass on.

Sorry, but your wrong. That is the correct stock N/A OS for 2008 FJC. according to Justin who quoted it from HERE pg 44.
But I was wrong in thinking that this was the correct OS for my TRD S/C. It's not, 😢😭!

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. Correct?

I have a 2007 FJ AT 4WD- so, according the the TRD supercharger instructions, the calibration ID is 33545000. The supercharger calibration ID would be 3YWK0400.

So, for me to be able to change any parameters HPtuners has to unlock this specific ECU, correct?

Right now, my truck is stock- no supercharger. Does HPtuners build a stock base tune for that, and one for supercharged, based on the TRD reflash?

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. 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.

I see. Thanks for clarifying this, so I'd be able to test the MPVI2 on a 2008 FJ, huh... :sneaky:

My understanding of the tuning process is very limited, it's baby steps, no check that, I'm barely crawling. So with that, the answer is yes, HP tuners have to crack the code. So far, for us that OS calibration file is for a naturally aspirated 2008, calibration ID 33555100.

Here's my story:
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. 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....
I bought new FIC injectors last month, November, for my FJ installed it and found out it doesn't work with my Ucon. It ran like CHIT! Emailed Scott (itronix Ucon) and he verified that those injectors won't work with the Ucon. Bummers! Okay, then instead of taking my TRD S/C off again and switching injectors I decided to try the HP Tune. It's a lot easier, a hell of a lot easier to pull out the Ucon and plug in the MPV12 in the OBDII port than pulling S/C, injectors, etc... Got with Justin (JustDSM) and found out it hasn't been updated yet. Then I submitted a ticket for the calibration update. (which mistakenly was for a N/A engine, not a TRD S/C engine) Received an email from HPTuners with info on update, got with Justin again and then realized the mistake after he read my ECU data. So I'm back to submitting another ticket for the 2008 TRD S/C calibration ID.

The update for the tuner took roughly 5 weeks, I was informed by [email protected] via email. The MPV12 is not listed or advertised for FJ's on their website. As far as I know I'm only one of two FJ owners that bought it early, but I'm the only dummy that has stumbled and bumbled to were I am now. :confused:
Aloha, J.

Okay, got an email from Justin and he stated the S/C update has been out for awhile. Went back to the beginning of this thread and saw where Doc posted the same. Very cool, I have scheduled an appointment with the dealer, this Wednesday to get a reflash to TRD OS 3yWk0400. After that I'll plug in the MPVI2 and see if I can read the ECU data.
Hope it works!
Aloha, J.

That’s great. Please keep us posted on how the refflashing goes for you.

Just to make sure, both tunes you mentioned are for the 2008 FJ, correct?

Who should I contact to get the ball rolling on 2007 FJ tunes?

Any way to get the calibration ID based on the ECM numbers? According to that sheet there are two possible for 2008 if i'm reading correctly? I took a look at my ECM and those numbers aren't printed on it. Assuming i'll need to connect a scan tool or something?
