Which EMS to buy?
#22
well getting something thats a boost controller is not what im worried about. i have a Greddy E-01 bc for that.
im looking for something that will give me the ability to switch between a racegas tune and a regualr driving tune. currently im in lubbock, 500 miles or 8-9 hours away from houston, and i cant be traveling back and forth to houston every time i want to get a tune.
i am also looking for something that will give me full control of the o2 sensors. im sure as most know, the problem with running racegas(leaded) is that it destroys your o2s. i dont have cats so i can run leaded.
i guess in everyones opinions, should i go return fuel system, EMS, or transmission, because they all seem to end up being about the same cost but each yield different results?

UTEC falls on its face when you stroke your engine or install some agressive cams (can't tune idle so well, can't change the map for the off boost load points etc.), AEM's problem is that it is a lil bit complicated and not user friendly but it is a very good solution. If cash isn't a problem go with the MOTEC M600 or M800, you will have to ask someone to make a harness for that. MOTEC will be around 5500-6000 $ when everything is complete and your car is tuned. As a conclusion, i'd reccomend going with HYDRA EMS as it is only 2500$, has great control over your engine, very user friendly and have good base maps.
As far as Motec isn't that too much for a street car, I thought it was a true stand alone, and you would loose all your VDC/ABS/climate control/ etc...
As I understand it Hydra is a full Stand alone, the VDC/ABS/climate control etc. is already recorded on the Hydra EMS, with tunable base maps for engine control.

How many times/how much do you have to spend on a tuning after you guys TT your cars to make them idle and run correctly? (running well, not just running). My friend had a newer eclipse that he S/T'd and he said the tuning was a nightmare and the car was never the same again. It was really hard to start in cold weather and was always finiky and never reliable...

We have had ZERO issues getting cars started and running on the UTEC..

Never said AEM is released.
Good to hear that soon UTEC will be available to raise idle.
UTEC is the best system (not only for Z but also all the other cars that UTEC is available) if you aren't going for something extreme. When you go extreme by upgrading stock turbos with much larger ones, really big injectors (>650cc), stroker engines, agressive cams, then you need a standalone.

You can not do this with UTEC as much as i know (when you try to do it with utec you need to change all the off boost load points just to tune idle). 650cc injectors are okay but how about some 850cc injectorS? How about tuning map load points when overlapping occurs with agressive cams? These are not controllable with UTEC sorry

THe UTEC as controlled 750cc injectors on my car no problem..Correct me if I am wrong, but if your cams overlapped, you would not build compression in the motor, cause you would be opening the exhaust and intake valves at the same time..

nice to hear that utec can control 750cc injs without a problem.

I say for current go with UTEC, user friendly and reasonably priced... Ive had personal experiance as a user, tweaking systems on AEM, TXS, and Hydra. I have nemesis on the MR2 and love it beyond what i thought even i would. it came down to myself and another owner who has AEM who has recently ditched for Hydra. we made similar power but mine was uned in far less time...
i cant decide because unless ou are goin for crazy like 800+ hp i dont even see why a Utec wouldnt cover you. Id prolly have gotten it for the MR2 if avl.

well just to let yall know i bought the F-CON SZ from HKS. it uses all the same harnesses as the VPRO but is like the e-manage ultimate. with a tune and all the necessary harnesses my total is coming out to $2000

I would recommend the UTEC for most people. The F Con V Pro is an excellent ECU but about the same price as a full Motec M600 by the time you add everything up. Motec is, as many folks will tell you, the ultimate but overkill for most street cars. Also setting up and tunning any standalone setup is going to take far longer and cost far more than tuning a UTEC which can be done in 1-2 hours. I have spent an entire day and then some tuning a Motec from scratch. Another great option is the Hydra which will bring a standalone system into the affordable range but sadly is not yet available. No ETA.
