1GR-FE F/I Mods and Dyno's

Forgot to mention that the dyno was done at 4th gear, I'd assume i have a slight amount more than 300 hp when in 5th gear....correct?

 

Shortly after installing the tune, I kept running into posts complaining the AFRs were dangerous on this website. So I rushed to get it dyno'd to check and make sure I wasnt potentially going to blow up my engine.

 

Being 1:1 in 5th, yes. However, using fourth prevents you from hitting the speed governor on the dyno. Plus, fourth is close enough to 5th.

 

Magnuson's tune is independant of Bully Dog's. Just uses their device to load the firmware.

 

Im just grasping at straws to justify I have more HP than whats shown

 

correct, so whenever points the blame at BD for their SC tune not going the way they want, it's really Magnuson's tune

 

Idk, are you sure? I've gotten indications pointing both ways. BD is supposedly revising a tune for me, not Magnuson.

 

Using the 3" pulley seems ok. Using smaller pulley brings the issue.

 

Bully Dog and Magnuson have their own independant tunes.

 

They do? For superchargers?

 

Quoted it earlier, from Gadget at URD. Don't remember which thread I posted it in.

 

From Gadget on XRU. Quote,"

[Gadget, post: 988181, member: 15"]URD stocks the Magnuson supercharger kits.

The 4.0L system is sold two ways:

1. One with tuning. This one is CARB approved and comes with full warranty.

2. Without/Tuning. This one is not CARB approved. Does not come with a warranty.

The CARB approved tuning version uses Magnuson's own proprietary calibration file and uses the included BullyDog device to flash your stock ECU.

URD has done some testing and the Magnuson calibration file is different from the Toyota/TRD dealer reflash. It is mostly in the VVTi system and it does not make as much power.

URD does have a calibration file for our UCON-EMS that will cover either the Toyota/TRD reflash, or the Magnuson Reflash, or even NO REFLASH at all. The UCON can run that Supercharger better than either reflash.

OK, options. If you live in California you should purchase the version with tuning so you can get the CARB sticker. If you do not get the version with tuning you cannot get the CARB sticker. Toyota is not supposed to flash your ECU is you do not have a TRD version. Yes, some people with contacts are getting their's reflashed at the dealer. Just remember you cannot unflash it and go back to stock.

You can get the Magnuson and the UCON and that makes a great combo.

Of course the URD Supercharger system is still the best......

If anyone has any questions, let me know."

 

Does anyone have a video of the exhaust cam gear installation with the new UCON?

 

No, but you can look at the apr one on youtube

 

At the end of the day though, can this cause issues with my warranty at the dealer? Since neither are a TRD product, could I ever run into issues?

 

Yep, I would say so.

 

Unplug it.

Apologies for bringing up an old post.

If I am reading this right - the aforementioned power to the wheels is made with the Roots style blower?

I thought they had a limit of right around 300rwhp and for more power the URD Rotrex was the only blower solution for more power.

Sorry if this has been covered before and I missed this.

 

At stock yes, around 300 hp, but if you replace the pulley with a smaller one (rotors spin faster => more boost => more power)
