TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

What he asked. No 93 in Colorado?

 

No 93 here. Just 91 for premium.

 

Altitude. I have seen pumps in Colorado that 89 was premium and 85 was reg unleaded.

 

How often do you drive your vehicle? If you don't drive it that much and haven't filled up in a long time then it is very possible that the gas was indeed bad. Yes to answer your question bad gas can cause misfire issues.

Yes.

 

Daily driver. Longest it sits is 2-3 days if I get a long weekend off & don't go anywhere. My daily commute is only 10 minutes. Lately a tank lasts me 3-4 weeks since I haven't trusted it for any highway trips.

 

If the misfire cleaned up when you changed fuels it is likely they have been receiving contaminated batches of fuel lately or maybe they diluted their fuel further than what they should of or as a whole now. My advice is continue to drive it regularly and if the issue no longer persists than the issue was fuel. If it returns it was purely coincidence and you will have to continue through with the checks.

 

Nope

 

Can weed be reconstituted into 93?

 

Oh i'm sure it can be rated at 93 something.....just not octane. Maybe 93 "high" performance rating.

 

The truck would be inoperable for a few hrs.

Or it would be stuck in reverse at the least.

 

As I understand calibrator helps if you don't have dealer flashed ecu. I do. I understand you don't need it when going with the ucon ems which I will buy in the future. Steve probably would have recommended it if it was necessary.

 

If you go UCON in the future make sure to get a stock non flashed ecu.

 

Why is that necessary? I'm new to taco land and am learning as fast as I can.

 

Because despite the advertising it doesn't work well with the TRD flash or the Bully Dog flash.

 

Good to know. I'm understanding bully dog doesn't offer anything for my 2015. I may be wrong. I'll check with urd before buying. Thanks

 

Do you have personal experience with this issue?

 

It's a well known issue...Loginfailed I believe was the 1st to experiment with the UCON +TRD tune. The TRD tune messes with the cam timing and makes it much more difficult for the UCON to work optimally. Ultimately, people that had TRD ecu's then went UCON bought stock ecu's later so it would play nicely with the UCON.
Oni was around during that whole era of experimentation so he knows what he is talking about. We should all thank @loginfailed for his time, money, and effort to resolve this.

 

As mentioned I'm really new to Toyota's. So much to learn. I'm greatful for this forum. Y'all are appreciated!
