I'm kinda on the fence on this so i would like to hear your take on this. I'm currently running an AMS 35 R setup on my VIII. My initial plans were to go with ecuflash and use evoscan for datalogging. Right now i'm contemplating on going the piggy route with ECU+ for finetuning and doing logs in coop with ecuflash. Second option would be AEM EMS.

My car is not a daily driver, but i would still like something kinda simple and with enough features, wich is why i like Tom's piggy, but still, i know the full benefits on running a full standalone with big turbos on an evo, specially when you can eliminate the dreaded MAS Dunno

Opinions ?

 

what types of emmissions laws are over there???


Thats the biggest reason I know I havent bought a standalone ems. I dd my dar and need to get it inspected once a year so I have to have the OEM ecu in place. I the the ECU+ is a great product and plan on running a gt35 and an ECU+ w/ a blow through setup to get rid of the stock maf.

You should also try to talk to Tom specifically; or Malibujack would be another great person to talk to since hes running a 35r, ecu+, 1000cc injectors, blow through, etc....and has nothing but good thing to say about the ecu+

 

I will go with the aem computer. I work with it and it has everything you want to do to your engine. The flash is ok but my opinion I think that from my studies of how the engine works it jumps into maps and not always you run the same with the engine. But that is my opinion.....

 

Emission testing is pretty much the same, but it's a non issue since i would just swap to the stock ecu in case i need to get inspected. I forgot about malibujack and i'll send him a link to this thread not only for my benefit, but also for other members who might have the same question

 

Hey, I got your PM about this thread..

Anyway, there's a catch22 when it comes to swapping for emissions, and that is, the time and effort you will spend to get the ECU to pass, will also get the ECU working well enough to not need an AEM.

The AEM is a fully standalone EMS and therefore has features that are configurable, but in turn, it gives you alot of stuff to mess up. Additionally the further you modify the car with the AEM, the more difficult it will be to go back to the stock ECU and expect to have an easy time passing an inspection.

Assuming you HAVE to pass an inspection with OBD-II, then your best option is the stock ECU and a blowthrough conversion (in my opinion the ECU+ since you can also fine-tune and log with it)

Its not that you can't do what your describing, but the effort it would take to keep both in sync, would result in a car that ran great with a stock ECU, so it somewhat negates the need for the EMS.

Comparing the ECU+ and AEM is really not possible directly, since each has strong points and a specific purpose.. But the stock ECU, and ECU+ are a potent combination that will give you most of what you'd need. As we learn more about the stock ECU, the rest of you guys benefit more from what we learn. And there's still a few dozen tables yet to define..

 

Thanks bro, that's basically what i though, especially with the specific goal that i had in mind , a 11 sec car that's confortable to drive and passes emission testing. I still would like to know how would the car behave in VTA conditions, running the blowthrough gm vs. the stock maf.

I'm stalling like a madman since i'm running a Tial and i really wanna know if ecu+ could at least mildly solve this problem. If it helps, then i would definetly buy it with a tactrix and start the whole tuning ordeal myself

 

The only way to solve that problem is to run a blowthrough MAF, nothing you do with the stock MAF in place will solve a stalling problem with a VTA Blowoff valve, at least without causing other problems.

Since my blowthrough MAF setup is after the blowoff valve, I do run a VTA setup, simply because my 4" intake wasn't built with the fitting to recirculate. Normally I'd recirculate it regardless.

the ECU+ works great with a GM MAF, there are more things in the works from Tom to make it work even better and have even more value added features in the ECU+ Since its only his "planned worklist" I'm giving him the option on whether or not he wants to discuss all of the new features he was proposing.

 

thanks MJ for chiming in....its always great to hear your guruness at work....lol

have you switched form your ford blow through to the gm setup yet?

 

no, not yet.. I need to do some work with another type of engine management device for a bit so the current setup stays for a little longer.

 

And on that note, were can i get the gm blowtrhough setup for my evo ? Does it come with the intercooler piping ? Were can i also get the gm bar map sensor so i can log boost with the ecu + ? Sorry for all the questions, but i'm really considering getting one.

 

There's a ton of sources.. Dejon Tool, either their website or MachEvo sells an upper intercooler pipe.

The GM setup is something you piece together, but you can buy all the parts from one of those vendors. And YES, the GM 3bar sensor works with the ECU+, I use it, along with the analog 5v output of many wideband sensor setups (in my case the PLX wideband since my TurboXS tuner pro is calibrated to match that)
