TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

Outside of TW and FB I haven't even heard of OV. This will undoubtedly hurt his business. It's a shame. I always felt he had too many irons in the fire and needed more helpful hands. Hell it took him over 3 months to unbrick an ecm for me that he said he would have back in my hands inside a week.

 

He’s not well liked on the Tundra forum either. But he’s the only option there because no one seems to know what HPT is other than one person.

 

or mazda. i did some checking before i bought ovt.
i should have read the writing on the wall.

 

@12TRDTacoma ,thanks for the confirmation.
question y'all-
last few months my afr #s hit 11 under mild throttle where it used to be 14.7 this is far below methanol start. idle is less than smooth so im changing plugs and fuel filter hoping that fixes it. no trouble lights either. anything else i should check?

 

Send me a log brother!

 

just spoke with hps. red is backorder until mid july. blue and black radiator hoses are still available.

 

Have you cleaned the MAF and TB lately? that's always where i start with rough idle

 

n

no i havent. about to do a spring cleaning of the meth nozzles so ill include that. brake cleaner for the maf correct?

 

No sir you're gonna want MAF specific cleaner. CRC is the brand i use. I dont think it matters too much what you use on the TB but the MAF is sensitive from what i've read

 

been spending my effort in other ways. my neighbor got me cost plus 5% on a new deer sweeper.

 

thats right. last time i did use that. then said screw it and bought a new one. at least i have a spare. thanks for correcting me.

 

Gonna need to check your fuel trims @White lightning boosted

Either send @JustDSM a log or if you want to check your fuel trims and send me what they are I can help you troubleshoot as well.

 

What's the most useful logs to capture with HP Tuners?

I recorded a few dozen WOT while on flat, downhill and uphill sections of I-70 going west of Denver into the higher elevations...

I'll export to CSV and overlay with my GPS tracks to find some more interesting logs from that…

 

Use the channels configuration file I posted in my FAQ

Very helpful.. I loaded the tecumesh file before logging and should have recorded all this data.

I’m more wondering what driving conditions are useful for logging to get an idea on open/closed loop conditions. Can you tune both or just closed loop?

 

Depends on what you’re trying to see/tune.

For an overview of how things are (in a general sense) a mixed bag of driving will give you a snapshot of how things are running and steer you on where you might want to focus on if you see anything outside of what you’d expect.

With that said all data is good data when viewed through the right filter(s).

You can tune closed loop (just not the stoich point). And open loop is no problem.

 

Cool, I’m looking through Techstream now and I see so many live data streams… is the torque converter lockup in your techumesh file, @JustDSM ? I have it displayed on my UltraGauge, but I’m pretty sure the custom programming settings I used aren’t displaying the correct value.

 

It does not as for general tuning I prefer to keep the parameters paired down a little and the trans stuff isn't needed to dial in the engine.

However, attached the file I'm attaching here has the Auto stuff as well as the standard channels as part of Techumesh. Load this just as the instructions in the FAQ show you for Techumesh.channels

If you have any issues let me know and I'm happy to help.

 

Schadenfreude

 

Guilty! Sub’d to that infamous thread. We’ll, just mostly to make sure the boosted brethren are staying out of trouble.
