small single kit with oem ecu?

hi

is it possible to drive a single turbo kit with the oem j-spec ecu?

small one or something like that.

is it possible to plug 550ccm injectors to avoid burned pistons?

thank you

yes. I ran my T61 for three years on 550's with a simple fuel controller (SAFC). Not the best setup, but found no det at re-build time.

No chance on a jspec. Uk/US/Euro spec just about at very low boost, but its hardly ideal

Edit - you can't just install 550's in the jspec, you need a resistor pack and at least a piggy back ecu to adjust the fuel ratio

edit: ok, stopped dreaming, thanks homer :-D

550's @40psi via (yeah, I know!) FSE. Always used a wideband.

Much better now with 650's and EMU.

Edit: Although have always used 103 Ron and water/meth inj.

Would an SAFC2 not do the job instead of piggyback?

Isn't that a piggyback too? I could well be mistaken but thought it just hacked the injector wires and modified the voltage to the stock ECU (Same as any other piggy-back)

Oh I see what you're saying. I wouldn't call an SAFC a piggyback ECU myself but I take your point.

Fairy muff. If I understand it the EMB only clamps 3 more wires than the SAFC2. One to adjust fuel cut, the rest to simply read signals like air flow voltage. Its essentially doing the same thing aside from the extra features like fuel cut (in fact that might be the only one apart from the data logging!)

Not quite, SAFC uses AFM or MAP to fudge the signals,

EMB can work off air flow/map and + to injector DC, can adjust ing timing, fuel cut, speed limiter, anti stall, V-tec, + sub injectors,

so just a bit more;) and EMU is not a long way off stand alone.

Ahh

But essentially the SAFC is just a piggy back (fudging stock signals), same as the EMB, EMU, etc ?

The SAFC is an amateur, whereas the Emanage is a professional signal fudger;)

Not interested in the 1000s of things the EM can do; question is; what can it really do above an Apexi SAFC for the SUPRA.

- more fueling points?

- ignition timing? - this is a good one.

- Speed delimiter (good, but useless if you already have one)

- Fuel cut (same as above)

- Anti-stall (not sure whether this is applicable to manuals)

What else..?

The Ultimate can do a lot, go here and take a look http://www.mohdparts.com/emanage

the most useful for the supra are the injector maps, you can add and take away fuel directly in the form of duty cycle, ignition maps, you can run up to four different maps, individual cylinder adjustment, water or air temp adjustments, mappable auxiliary outputs to switch thing on and off, can be used for NOS or such like, the sub injector map is good for water injection.
