Magnuson Supercharger Mega Thread for 16+ Tacoma - Unboxing, Install DIY, Dyno Video

Hmm… Yeah might wanna have a good sit down with those guys.

 

That is sound reasoning. I am less afraid to take the truck out for errands tonight then. Probably just an exhaust leak from the AFR bung. I thought I read a few (dozen) pages back that the ideal AFR reading under load is around 11? I never saw mine below 13.1. Granted, I didn't get on it, and, its 0.4 too high from where they tapped the exhaust (post second cat). So it was running in the 14.x value range 95% of the time I was driving it home.

 

Interesting info about the p0660.

 

11AFR is rich af. Lol

As a "general" broad rule of thumb, 12.5-10 AFR is the range for boosted applications, at WOT.

Leaner for NA.

The range then changes based on application. 11 for these engines is super rich and safe, can lean out.

 

You were seeing 14.x for most of your drive because you didn't need enrichment for most of your drive.

 

So 14.x with a +0.4 offset is reasonable at slow speeds? I think that is what you're saying

 

On a positive note, they did leave the VFTuner OBD2 plug/cable and case in the front seat. I already have the Tactrix cable, so score!

 

Yeah you're fine

 

The magnuson comes with a cable, login credentials and enough credits to flash the truck.

 

Anyone want a Tactrix cable on sale? @jstemp Drew at RSG just mailed me the tune file, it does say V7 in the file name (not V8). But Drew said it was the new tune from Maggy

 

Tune names I've gotten from Maggie so far

04B33_V7_PCO_MAG_SC_PR1_ 1641.vfc - First flash on 5/5/21
04B33_V7_PCO_MAG_SC_PR1_CS_TC_1641.vfc - Updated flash 11/15/2021
04B33_V7_PCO_MAG_SC_PR1_CS_TC_1641_456.vfc after gearing 01/13/2022

Not sure what the CS_TC changes included

 

I am so glad I had the time and tools to do my install. Yes no ACIS on the AT - just tape over the plug and tuck it aside as the ACIS unit was removed with the manifold. I do not and have not had any CEL for removal of the ACIS - Maggy knows of this issue and it was present when they got their CARB. No problem with it as it is a non-issue. As others have mentioned the rest is likely an issue related to added gauges for AFR and or Boost.

 

04B81_V7_PCO_MAG_SC_PR1_CS_TC.vfc is the file I got. I have 4.88 gears, not sure if that is reflected anywhere in the file name. I did mention it to RSG

 

Welp, I am off to run an errand and will get on the interstate on my way home. So I can give it a little juice and see how it does. THANK YOU for everyone here that replied to help calm my sh*t down and diagnose the codes.

 

I got the same file only for 04B91. I'm not sure but gears really don't change much with the manuals. Autos use it for shifting logic.

 

Last I had read, Maggy wasn't making tunes specific to the gearing?

 

my V7 shows 4.88's in the definition. Won't matter much compared to a tune that truly makes it drive like it should....YW SC Tune!

 

In the file name you mean? Or can I open the file in VFTuner and see it listed there somewhere?

 

Magnuson tunes are locked, you can't open them in VFT.

 

CS = Cold Start
TC = Torque Converter (adjustment for the CS mod adjustment)
456 = your gearing
