stock cosmo ECU or EMS??

hi guys!! I'm new in this forum and neeeed your advice for my FC3S 20b project!

does anyone have experience running his 20b with stock ECU (tricking it, thinking it runs auto tranny)?? it would be alot easier to do the swap if i wouldn't be concerned with electrical problems!

Pleeeease help!

if you dont want to sped alot on an ecu look at a haltech, tec3r or microtech.
just dont use the stocker.

thanks for you reply!
but why not using the stock one?
I'm not shooting for 500hp! I'm going to drive it stock (mild boost increase) plus my 2.5" exhaust system. i think that would be enough for about 350hp... and a lot of torque (that's the reason i want a 20b!!

with my t60-1 i had some hp beyond 4500rpm, and that's not very streetable here in switzerland

regs,

Listen to everyone else. If you are to spend money on 20b project, you don't want to cheap out so you could put useless auto ecu. If you only want to make 350 thats easy with 13b rew... why waste money putting 20b?

I agree with herblenny. the reason that you dont see alot of stock or near stock 20b installs is because it costs so much to do it in the first place and if you only want 400hp or less, thats easily achieved with a 2 rotor.

okok! i see your attitude! as especially onefastrx7turbo should know: there is torque!!!
with my t60-1 setup torque is available from 4500rpm, so how to achieve 400nm of torque like the 20b at 2000rpm with a 2rotor??

please don't misunderstand me: i don' want to go cheap, i just think the stock ecu is saving countless hours of adjusting timing and fuel amount ...

... and who can withstand the exhaust note of that thing

Well, I mean, the 20b will always produce more power and torque sooner than the 2 rotor will. But, its like, how much do you want to spend to have more torque 900 rpms sooner than a 2 rotor? Also, the stock ecu won't run an aftermarket turbo very well. You'll have tons of band-aid boxes to control more fuel, etc etc. Do a search on it, there has been one or two people that have sucessfully wired in the stock ecu but its NOT easy.

isn't the whole powerband much torquier?

my plan would be to install the whole longblock and run the stock ECU with the stock twins. that must be (in connection with 2.5" exhaust plus FMIC) sweet hp with a very strong powerband. as i mentioned, i'm not shooting for xtreme horsepower, just thinking of a strong, smooth, great sounding rotary engine to pull my 1360kilos (convertible). as for now i have enough of a 2rotor engine, producing 60-80hp from 1500 to almost 3500 ... believe me: THAT SUCKS HERE IN SWITZERLAND!!

by the way; can you remember who's successfully driving 20b stock?

i'm gonna try to continue this thread!!

does anybody know, wich ones of the EMS come with oil metering pump control? i don't want to mix my fuel and oil as with my little two stroke racer from yamaha!

also what would be the main difficulty applying a EMS? am i in need of a compatible laptop or any sinilar device? im mean with an aftermarket standalone i'll have to setup the fuel amount for the whole powerband! are there any EMS with sort of factory setup for the 20b to start with??

thanks for you help guys!!

"now" is using the stock ecu, although i'd hardly call his configuration stock.

a standalone is a necessity. you should REALLY try using the search function, your question is a very basic one and as such has been discussed in GREAT length many times.

yes you're going to need a laptop.

yeah i know the "search function"! i've tried it for some topics, but the problem is; there is endless talking, flaming etc. and you have to read through dozens of threads just to get that bit of info needed!

sorry guys, i just thought there would be any experienced member that has the knowledge and time to give me some advice - not a whole manual, just what to go for or wich product to purchase - 'cause i think that's what a forum is for! i dissociate myself from those stupid-questions-asking-guys! just thinking it would be more efficient and polite from someone to just summarize the answer to my questions and give me a hint... i personnaly would do the same for sure, if someone came up with questions concerning a problem i've already successfully solved once!

... pardon me guys if i 'm completely backward! :-)

heres the quick and easy answer. If you want to do the tuning, you'll need a laptop. Buy the best ecu you can afford, and one that has local support for parts, tuning, etc. just as a personal preference, I'd stay away from haltech or microtech. too many bugs, too many glitches. i use a motec on my car, some use autronic, others use TEC3. Whatever you do, dont waste time trying to incorporate the stock ecu into the equation. it will give you nothing but headaches.

thanks man! laptop should be no problem! does the motec support the usage of the oil metering pump? 'cause that would be a main criteria! do they have alsready installed maps to start with the 20b or will i have to setup a completely new one!
i 'm coming more and more towards the conclusion that factory ECU would'nt be the way to go... there would be additonal problems with the wiring of the rest of the car (idiot lights, tach, speedo, ...), and as we know; factory manual of a cosmo is in japanese only!!

don't want to waste you time with my greenhorn-questions onefastrx7turbo, would be very glad if you could give me some hints on experiences you made with you motec, especially doing the setup for fuel an ignition! thanks a lot man by now...
