I was told I need to install the Dezod Motorsports AEM EMS Standalone Engine Management System in my 08 TRD Supercharged tC.

Yes I am aware I would get more power if I just switched over to a turbo but I want to keep the TRD charger.

Are there any cheaper alternatives that would work as well as the Dezod? Or perhaps a place to get it cheaper then $1749?

 

Supercharger isn't as bad as ppl say it is just got to watch out for it.(bearings) Y don't you use aem piggyback works good for me

I totally agree. I upgraded the bearings and pulley and i love the charger, its a great little unit.

The shop claims the piggyback would be a waste.

 

Hmm thats weird....yeah stand alone is better but not needed for the supercharger aem piggyback will work great or greddy ultimate (not the greddy blue) I got aem piggyback and just got tuned no probs (deff better then TRD tune lol). I got the 9.5 pulley dezod header and couple of other boltons

I have the 14 lbs pulley so they claim i would need the stand alone because of that.

 

Never knew they had a 14psi pulley for this s/c.. what ecu are you using now with the 14psi. If you don't wanna spend the money then u can always downgrade to the 12psi pulley I know that one can be tuned with a piggyback

Also when I got tuned I had to use a non TRD ecu cause he was having a hard time with it so i used my stock ecu. and they tuned it with my aem piggyback and its running fine.

Do you have a TRD ecu maybe trying with out the TRD like I did will work out for you

Also eBay will prob be cheaper for a universal one.

For a short while NST offered a 50MM 14 lb but they quickly removed it from their site when the complaints started rolling in about it blowing the chargers. I upgraded the bearings after mine blew so shes good to go. I want the keep the current pulley, I love it.

Im not entirely sure how the first shop worked it out. The second shop claims they just used the TRD tune and its not cutting it.

I found out from a friend I can use a non stand alone but the particular shop i went to the second time around only works with Dezod stand alones.

 

If you can take on a wiring challenge you can make a jumper harness to run an AEM EMS-4

 

AEM FIC should work just fine for 14 psi....way less than AEM EMS or AEM EMS-4.

 

Thats what I thought. The second shop said they only work with the stand alone so I think they were trying to downplay the piggybacks.

 

Try another shop if you don't want to spend that much lol

Ya I plan on it. I only have one other option in this city so that kinda sucks. Happen to know where to get a piggyback setup for a good price?

 

Don't you already have a piggyback how r you running the 14 psi pulley. You need to be tuned for that im guessing from what i been reading on here. And You can get one used on here or eBay if you dont want to spend alot and dont mind used// aem/greddy ultimate/ and some ppl been using unichip but check if there's a shop that tunes the unichip kinda hard to find

the aem f/ic is a better choice in my experience

It currently doesn't have a piggyback. That's why im running into issues. The first shop slapped on a pulley and intercooler and only used a tweaked TRD tune. Second shop said first shop basically didn't do anything tuning wise.

 

I definitely wouldnt say that a standalone is needed at this point. An FIC or Emanage Ult would work just fine. Ive used both, and both did well in the 300whp range. Youll just need to find a tuner familiar with the one you decide to go with.

 

Glad to hear it. I appreciate all of your input fellas.

I cant post in the classified section yet, anyone happen to know if anyone is selling one?

 

piggybacks suck your tuner was steering you in the right direction.
yes a piggyback system will "work" but it is far from ideal

 

Performance wise, whats the difference?

 

Agreed.

Huge potential for control, drive-ability and such.

14 PSI is a lot of boost for that TRD S/C especially without some form of intercooling. Even with it, that blower is just not designed to be run at that boost level. It will be hot air death for the motor.

Toyota's knock logic is very aggressive. If you where datalog the factory ECU, it's constantly pushing the brink of detonation at all times. Couple that with a non-intercooled TRD S/C, a piggyback that can only retard off of the factory ECU and I think you have yourself a recipe for disaster.

This is why they where steering you in way of the standalone.

 

Interesting. My unit is intercooled, as well as having the upgraded bearings to handle the smaller pulley, do you think I would still need a standalone?

Before this morning i was ready to go with the piggyback. You guys suck
