Magnuson S/C

I cant speak for how 'Good' it is to drive it, but def stay out of boost at the minimum.

 

Good info, I'll check... possibly before I owned it??.. thank you!!

 

It's ok, it works, I have driven without flash over 30 miles.

 

in and out of boost?
in the other 2-3 S/C threads I read in, ive heard that's extremely risky on the engine

 

Yes but I am looking to tow with it...

 

Where is @HolyHandGrenade for this discussion?

 

Staying off the boost, like said in previous page.

 

Here are the files, if the target calibration is not on the list, the flash is not possible: https://www.tacomaworld.com/threads...-gen-4-0-engine.454464/page-173#post-14231869

 

gotcha, I must have missed it. The way I read it, it sounded like you drove "normal" (S/C normal: ) without the tune haha. no good for the engine

 

As a matter of fact, the TRD flash didn't work good at all, it was as much lean (STFT 22%) as the stock tune was rich with TRD injectors (STFT -22%). I don't know if the ECU learned it during driving and that's why I got the very lean tune.
Has anyone else experienced the similar?

So, maybe better to tow. Or if driven, reset the ECU first (negative cable off for a half an hour).

 

They got it figured, were able to pull a program from their old system as the new one (with in the last month) wouldn't allow it... Drove it home and it feels great, however, I have nothing to compare it to. Power is very noticeable and very smooth all the way through the rpms... sounds good and no check engine lights or overheating or anything along those lines...

Driving it this weekend will be the test

thanks for the help and opinions... good or bad...

 

Glad you got it worked out. Sounds like you have some friends at the Toyota dealer that didn't just give up at the first sign of difficulty. Props to them for that.

 

If installed and tuned correctly I think the only regret people might have is that it still doesn't turn their trucks into a V8.
If you can swallow that, boost away!

 

I do yes... it took a little coaxing from me, but they made it happen and I am thankful, the Tech didnt want to try but the parts manager dug up an old progam...

 

All prettied up

 

Guages, intake, smaller pulley, headers, y-pipe, exhaust.....

 

So clean ... needs dirt.

 

Hey Rob. I had a remote tuning session tonight and the replacement UCON is running great now. It was running very rich, but the AFR's are spot on now
