89+ Turbo ECU pinouts

[Bondango]

are these the correct pinouts for the 89+ Turbo (or where they the same for the turbo right through the years)

They're the same as the ones on my 89 Turbo.

thats good enough for me, its spagetti junction and soldering iron time for me...a
nd on a techy note..did you know the 7mgte does not have "fuel cut" it uses "ignition cut"..amazing what you learn eh? :bigeyes:

[buttmunch]

and on a techy note..did you know the 7mgte does not have "fuel cut" it uses "ignition cut"..amazing what you learn eh? :bigeyes:

Its a bit of a misnoma "fuel cut" because cutting fuel at high boost would almost certanly spell the end for your engine.

Sorry to hijack the thread but can you confirm this anywhere other than speculation? I agree that the sensible route would be to cut ignition and fuel simultaneously but the TRSM only mentions that fuel is cut. I've been trying to confirm this for a while as it makes the difference between fuel-cut being dangerous and not. It seems to me that fuel-cut and the rev-limiter use the same procedure.

[Bondango]

i have been studying said scenario for a while now, and wondering how to raise the rev limit and fuel cut. Using an FCD clamps the signal, but rev limit is another story. So out there in the world of bits and pieces my Jap contact is looking for the Greddy Rebic LC, this removes fuel cut and raises the Rev limit. Now the wiring harness only interfaces with the ignition circuit of the toyota ECM, its runs its own G2 signal, IGT signal,EO2 signal, and taps into a few others of which are earth, power, and speed signal.

So from that info i can accertain that the Fuel cut is obviously some type of ignition cut as the rebic dont interfere with any afm signals etc etc :bigeyes:

Up date, just found it also "taps" into the 3 signals for the injector banks, so basically all it can do from this is read the values from them? it couldnt actually cut the signal to them...but then again at Fuel cut, it could in theory apply a signal to them...


my head hurts :banghead:

[Lofty]

That sounds interesting and certainly feasible, although the TRSM uses the phrase "fuel-cut" when dealing with the rev limiter. If it does not interfere with the AFM signal then your assumption that fuel-cut is really ignition cut would be true, and to be honest the safest and most obvious way of controlling these issues. On a side note there is a thread on SM that mentions changing the crystals in the ECU to reduce the clock speed and raise the rev limit that way. Sounds like an interesting piece of kit that you are researching. What sort of cost are you facing?

[Bondango]

well the rebic ecu2 which is for the 89+ cars is like gold dust now, they used to go for around £80 - £100, i have eyes and ears in japland waiting on one to surface if i can get it for that price.
I can get a complete Rebic III injector controller (i have the mark 4 version for the celica) for £150 which can control up to 4 x 900cc injectors, so combine the 2 and you have a raised rev limit, no fuel cut, and enough fueling to run the biggest turbo you can put your head inside..................................all theory off course...... :bigeyes:

but for £100 for the Rebic LC or CPU2 (89+cars) this is what you get...

"This is what I use on my brown car. It is an "all in one" box in that it is a fuel computer, fuel cut eliminator, speed cut eliminator (Japanese spec ECUs) and rev cut eliminator. It also has IPM (Injection Pulsewidth Monitor). There is a potentiometer on the side of the unit that allows you to increase or decrease the entire fuel curve by up to 50%, either way. The Rebic LC allows you to run more boost (I have run up to 22psi) and still remain in the "safe" a/f and EGT zones. If you want a "single box" to do everything (other than allow removal of the stock AFM) this is the product for you. They are few and far between as they have not been produced for some time."


nuff said :yes:

[Nodalmighty]

For the record it cuts FUEL ! As injectors are ground active any wires tapped in can ground the circuit as this is how the e-manage works. I don't know why your pissing about with rebic stuff, it's as old as the hills and twice as useless. :no: Get yourself an e-manage and E-01 as it's so much better.

Becuase its £90 and plug'n'play and is cheaper than an FCD but does a lot more :)

Nod, i have the rebic Iv AIC which is the dog'g danglies when it comes to Additional injector control, granted the LC and CPU2 are old, but then again, so is the technology in the Supra. I guess they go hand in hand as they are just doing the job they were designed to do :bigeyes:

So you don't want to buy a second hand e-manage then, Damn! :crybaby:

LOL !

Your MK3 might be old technology mine is state of the art :duck:

ahhh Nod my mkiii is state of the art too i would imagine, but on a budget, i cant see why people fork out so much money on stuff in the UK. I just got a Suprasport Stage 3 clutch for £310 last week. Apexi safc ii and AVCR set me back £450 for both, digital oil pressure, boost, Air/fuel gauges for £100....and been offered RC injectors and clips for £280 and a Walbro for £90 and thats to my doorstep.. you see im poor and learned that all flash dos'nt mean all cash especially if ya know were to look. Im probably the most stuck up person you will meet when it comes to an attitude towards UK performance specialist's - I dont mean to be offensive by it, proabably just sore that i didnt follow my dream 11 years ago of doing it when my mate started importing cars from japan... we live and learn i suppose :yes:

the mkiii was an alternative "run-about" car for me, but it was mint! and had a lot of the work done that was important, suspension, exhaust, gear box rebuild, engine overhaul etc etc. I waited 16 months on one, and traveled from belfast to bournemouth to pick it up as i was in such good condition so in a way i was lucky, and as some might remember...i wasnt...but thats a different story :no:

Going off topic.

I can understand why people pay so much. When I brought all my stuff for the MKIII, I didn't fancy parting with thousands to some company who were thousands of miles away e.t.c, I just wasn't that trusting, and what if it was broken when it got here?? what about warranties?? sure you can send it back, but it's hassle, I'd rather pay the extra, and did, for someone else to have all the hassle if it went tits up.

Look at Tein now, sure you can get it cheaper in japland, but if anything goes wrong, they wont touch it at Tein UK.

The majority of UK mkiii owners seem to haggle over the last 5p, have to be the only owners like that.
They're all eager to shim the wastegate as it only costs a few washers, and increases the performance, but don't want to spend on decatting which the car desperatley needs, then moan when it breaks down :duck: :D

[Bondango]

Too true nick, i understand that bigtime mate, also as a business you have to make a profit or why be in business in the first place ...as for us being tight arases - guess it was just the fact that a once rich mans car is now in the hands of us mere mortals lol i looked at my bill for toyota parts and the crankshaft oil seal was more expensive than the timing belt!!!

How much for the washers??? and do you do free postage? :) :cheeky:

Remember i have your old turbo!!! How meany washers?? lol :)
In all honesty what your saying is correct, i personally would pay a little extra for piece of mind. At the end of the day you may think you saved a couple of hundred on something that is worth a grand but if it goes tits up you can loose out big time. Stuff like filters, zosts, break disks, engine mounts :) are fine to save a few bucks on by buying from abroad (only if they'r a reputabill company) as they generally dont **** up.
My 2p lol

[Nick]

I'm not saying don't put washers on (by the way there is 6mm worth on there) I'm saying people do it as the first mod cause it's the cheapest, i can honestly say, there wasn't a washer within 10feet of that car before the exhaust was done. :D

[Bondango]

what about a wind up on ebay?

7MGTE boost kits....

£10 Kit 1 - 20 bhp
£20 kit 2 - 30 bhp
£30 kit 3 - 40-50bhp (must be used in conjuction with a de-cat pipe)

Gauranteed to work! No stupid electronic trickery, easy to install with basic tools ,all kits upgradeable, life time gaurantee...

Sworn statements..

marty "I couldnt believe this kit when i got it, after installing the 20bhp kit, my boost gauge went off the scale, and my clutch started to slip with the power my engine is developing..best £30 i ever spent!!!"

:) Was only having a laugh. Oh by the way i have got me a decat system (of sorts :) ) Knocked the honeycome out of the cats :) Now hows that for a cheep ass penny pinching mod lol. (just a tempory measure till after billing)

That only works if they don't know you are a MK3 Turbo owner. Othewise they'll just think that's bloody expensive for a handful of washers, they must be stainless.

Nick could polish em, bling washers! :)

on another note, i met Kipper at the Jap-heaven meet, and when i told him about the washer MOD he looked at me as if i has 3 heads lol :cheeky:

So what is the washer mod? Does removing the windscreen or headlamp washers raise boost or something? Or do I have to take all the washers out from all the bolts on the car to make it lighter? C'mon spill the beans as I don't want to have to pay £30.00 on ebay.

:duck:

That is what the TRSM implies but can you confirm if ignition is cut at the same time or not? If it only cuts fuel then hitting fuel cut or the rev-limiter could do serious harm to the engine, through potential detonation. If fuel and ignition were cut simultaneously then it's not so much of a problem.

[Adam W]

It's not gonna detonate if theres no fuel in there to explode! It cuts ALL the fuel, switches the injectors off entirely, not just reducing the fuelling.

Yeah, but at high RPM there will always be some fuel/air mixture left from the previous cycle. I guess it won't be much though, as you say. Probably not enough to cause any damage.
