TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

They built mine in six days. I picked it up there in Murrieta. Saves the $200 shipping charge.

 

how is the fitment? I'm a little concerned that an aftermarket hood mounted to aftermarket fenders might have some pretty knarly panel gaps.

 

It also increases boost. So in addition to a reduction of timing due to the change on density the amount of boost climbs as well.

 

I have a first gen S/C with URD 7th. So truck is shutting down intermittently. Was occasionally, now 2-3x/mile. Tach to zero. If happens at stop I have to turn key to off position first before it will restart. If not it just cranks.

Code P0335 pops up, Crankshaft position sensor A circuit, but on swapping sensor nothing changes. Even tested sensor and it is good. So I did continuity check on wires running from harness plug back to ECU E7(C) plug and they two check out. But continuity through URD tuner is good pin 6 but not on pin 12. Now pin 12 is the splice to the URD module. It seems as though I should have continuity running into and then out of URD module.

Does anyone know if there should be continuity? Can anyone help me out?

 

This true @JustDSM ? If so that would be nice for an ECA!

 

Forgive me, I have been tied up with matters outside the forum so I've not followed along with the last few pages.

There are no spare outputs on the ECU unless you use the N/A calibration with the TRD/Magnusson supercharger (i.e. how TacomaBeast had his truck tuned). This would allow you to use the ACIS solenoid output for "something". But this output is disabled with any of the TRD calibrations.

What are you guys wishing to trigger? Perhaps I can recommend/suggest specific external controller that is programmable.

*EDIT* ECA as in ethanol content analyzer? If so there are no spare inputs to the ECU. It would require custom coding to patch that functionality in. A bit beyond currently available solutions.

True "Flex-Fuel" capability is probably not going to be a thing for our trucks. If E85 or some other mixture is really something someone wants, it's going to require a dedicated tune for that ethanol content (+/- 10%).

 

Much appreciated on the response. I’d be nervous driving around on e85 without an ECA. How would you really know the content when filling up. It could be anywhere from e40-e85 since ethanol at gas stations is not very well regulated.

Maybe some type of funnel device that could measure the content during fill up?

 

Correct, you have to measure/inspect the content. Adjust tune as needed. Not really feasible unless you’re comfortable with fueling corrections.

 

Thank you! I have a lot of learning to do on this - really all of this. HPT ordered and waiting for arrival. Already confident I will be going down the meth/water injection path once I get settled out with things.

Trying to understand the pro/cons of a meth/water system that reads pressure only like Snows stage 2 kits vs a Stage 3 kit that reads pressure and spark timing.

Need to find a good book to read on this....

 

Seems the stage 3 snow has more adjustability vs the rest? @White lightning boosted

I just wish they could design a better looking module. That stage 3 by snow looks awful.

 

I did a test fit before painting. Gaps to the OE fenders weren’t bad. Couldn’t close the hood all the way at that point since I still had the old headlights on there. But, for a fiberglass hood, it was a surprisingly good fit.

 

I'm still having a hard time seeing exactly what needs to be done to modify the tensioner for the double pulley. Do you just grind off material until it clears?

 

When it’s not your day it’s not your day. And it’s Monday. Buttoning up stuff on rear suspension and pinched a brake line
Well I got that on order and moved to the front to swap the SC belt. Easy enough until I found bits of old belt sucked behind the crank pulley

Got scared to try the starter bump method so I learned how to pull the radiator and fan hoping the big impact would do the trick as it always does. This was the first time I was disappointed in it as it failed. Starter method worked in the end and all of 1min to get bits of belt from behind the pulley and start going back together. Sucked but gave me a chance to finish 360 welding some of the engine cage tubes and flush the coolant.

Just one brake line away from being able to this weekend.

 

its not a beauty contest but, yes. they could have done it differently. yes to the adjustability. its quite impressive. my biggest complaint is that 8 bit nintendo game boy screen thats near impossible to see. how about dot matrix black and white with enough contrast to see??

 

I can't even picture where that box would reasonably mount

 

i figured it out. put the pulley on the roush where it binds if you tighten the bolt. grindind to make it work. i did mine in just moments with a 4" angle grinder and 120 grit.

 

It sounds like you just like to work brother. Hahaha. Sorry to hear about your troubles.

 

You mean original 8 bit gameboy game

 

yes!
