I have a Magnuson Supercharger kit for my 2013 Land Cruiser and need an ECU calibration. I contacted Magnuson and they won't do anything as it is a used unit. Does anyone have a calibration or a recommendation? I already have an HP Tuner

I would go to the Tundras.com and ask in the performance section who the top tuners are for HPtuners.Yes, I need a custom tune for a Magnuson Supercharger. I contacted Overland Tailor Tuning, but they won't tune with the tuner I have.
HP Tuner will do the job, does the Magnuson comes with uprated injectors? I have a 2008 LC with Harrop Stage 2 (with uprated injectors). I personally did the tuning after i could not find anyone familiar with Toyota. Most tuner that use HP Tuner only cater to American cars. Familiarity of the ECU mapping differs from car manufacturers, therefore parameters and how it was implemented varies.
At a minimum you need to adjust the MAF scaling, if you have the uprated injector then you need to program in the injector manufacturer parameter into your ECU. These are the two important things you need. I did not change any of the timing nor other parameters. The truck run good.
That's exactly what i did collecting files and comparing them. Are you using the stock air box? Also the AIT that is located on the Harrop charger manifold is susceptive to heat soak (can cause Check Engine) specially when highway run then park. Try using the stock factory MAF/AIT and see if that clears it. I also used the AFE intake system.Thanks all for your input. With the help of google and the hptuners forum I got it done. I opened my Land Cruiser file and a Toyota TRD tundra tune with HP tuners, compared, and copied all differences to my Land Cruiser tune. That only copies parameters where the tables are the same. MAF, Injector, transmission, cold start, and a few others all copied over. I opened up the timing and VVT tables and manually copied that data till to make It essentially the same. I couldn't copy and paste as the number of cell blocks was different, but was able to get a very close model by coping select columns and using the interpolate function. Loaded it up and it runs like a champ.
Wouldnt running the factory AIT feed the ECU the wrong temp data? The temps after the supercharger will be hotter.That's exactly what i did collecting files and comparing them.

Not an expert on this mater, just able enough to do and observed. Hopefully someone can share their knowledge.Wouldnt running the factory AIT feed the ECU the wrong temp data? The temps after the supercharger will be hotter.
Yes, down pipe before the cats.Where did you put your wideband? I'm thinking of having mine in the downpipes, before the cats.
Perhaps this question wasn't directed at me, but my Magnuson charged Land Cruiser runs perfectlyHow’s it run
It run very well. It feels smoothness of the factory except with more power. Its coming to the point of needing a bigger brakes to slow down the rapid weight.How’s it run
sound like you need to get on that power brake 15% off sale! i'm getting very tempted to start looking at boosting my 200 soon. did you take your truck to carb connection in kirkland?It run very well.

I’m looking at it also. It’s the cost of a c5 thoughsound like you need to get on that power brake 15% off sale! i'm getting very tempted to start looking at boosting my 200 soon. did you take your truck to carb connection in kirkland?
Yes took my truck Carb Connection. I feel they specialized on GM cars and trucks but not Toyota. Maybe its a blessing they left the stock ECU rather than doing something that could have resulted to more catastrophic engine failure. Also it force me to learn the HP Tuner, the ability to make changes in a controlled manner is priceless. One thing that surprise me is that with the stock factory ECU program even with the 2X size injectors the truck ran and tolerate the calibration mismatch. The close loop system Toyota has enough range to compensate. Maybe on a newer models it will induce the limp mode, my truck is a 2008. I also confirmed difference between model years on their ECU table mapping and additional features. This truck now serve as a daily driver, heavy tow vehicle, family car and a bug out land rover with my 3.5" lift and 35" tires. Love it! I highly recommend supercharger upgrade, you just need a little effort getting it right. HP Tuner is awesome, even as simple of scaling my tire size to my speedometer, easy. I tried messing with the transmission shift points, definitely another area that can enhance the driving dynamics to individual personal preference, make change and if you don't like, revert back.sound like you need to get on that power brake 15% off sale! i'm getting very tempted to start looking at boosting my 200 soon. did you take your truck to carb connection in kirkland?
