Hey noob question
Since I am auto can I simply aquire a aristo ecu,aem map and iat,and simply follow this same conversion ? Meaning does the aristo ecu literally plug right up to a 94 sc300

all odb1 aristo ecus, supra ecu's and sc300 ecu's have the exact same connector.
they will all plug right in, but you need to do the wiring changes outlined in the thread and also you need to put in larger 440cc injectors for the jdm ecu's.
Also you cannot not use an aem map they are too large, the only one I know works so far is the stock TT map sensor.
a 2.5 bar may also work with larger injectors, but its not been tested yet.
The only limitation with the auto's is that you need to keep the stock throttle body which has the line pressure cable from the transmission attached to it. so if you are leaving the intake/throttle body stock you are good to go.
If you are swapping to like a q45 throttle body which doesnt have the spot for the extra line, you would just remove that line from your old throttle body, pull it some and make a knot so that its engaged some (you can adjust where you make it) which sets the line pressure at a constant setting instead of varying with the throttle. basically people used to lock it full lock to get quicker shifts all the time. same works for aftermarket throttle bodies on the ge.

Back to basics I guess. Plug gap, boost leaks, BFH.

Hi everyone am new to the forum... Just finished reading these thread for the whole day from page 1... Good info... My question to u guys is can the mod work in my 93 gs300.. if so am getting started right away with my build.

Well, I got a proper igniter and wired it up last night. Still slower than it used to be on the NA ECU. I figured it must be my resistors to the injectors so this morning, I BYPASSED them completely. I know, I know... risky. Anyway, no change, so it's not my resistors.
Back to basics I guess. Plug gap, boost leaks, BFH.
Back to basics I guess. Plug gap, boost leaks, BFH.
1. the ge ecu was running more timing/less fuel in boost resulting in a little more power.
2. if you are running the stock intake it may take some tweaking to get the ACIS Valve to work with the TT ecu.
if it is not actuating the vsv properly, it can make less power.
It needs to be short runners in all conditions, except when high % throttle and low rpms it should be set to long runners by the vsv conencted to the ecu.
The TT ecu has several vsv outputs, and when swapping ecu's the acis vsv is connected to one of them already, not sure if its the same though but should probably be looked into. I would have but my stock intake is in a box.
The acis can always be disabled and set to the short runners all the time to make god top end power. some even remove the throttle body thats in the intake completely.
There is a map of when the acis works around here somewhere.
did you gap down your plugs previously, try stock supra tt gapped plugs, I just drop those in.
yeah it works on all odb1 2jzge vehicles, same connector, wire colors on maf might be slightly different color for the signal wire, but still in the same place.

I am in the process of this, and I wanted to note.
You state that if one uses VVTi coils, they need the DS2 style igntors, and if they use TT coils, they need TT ignitors.
I'm not sure this is true, since I fabbed a Camry Coilpack setup for a friend's 2jzgte and it runs great with the TT ignitor.
Based on the idea both the 2j and 1m camry v6 both operate on waste-spark, and thus will interchange.
Now if we can find a way to run Internally ignited 2zz coils on a TT ECU without an external ignitor, we will be in business!

I know about the Camry coils and I think you need an FFIM for them. From what I can tell they are not as robust as the vvti coils. just by the physical size of the coil portion, the camry coil looks like a TT coil with a 2nd lead coming off of it, better than stock, but take a look at the vvti coils and they are just massive in comparison.
I know that you can get the TT ignitor to operate in wastspark, however, that is not the best use of an expensive 6 channel TT ignitor, it takes extra wiring and it is large and bulky. I have heard of poeple having ignition issues doing this but if it works i guess it works, I would still be skeptical about the dwell both ignitors are using.
as for the 1zz/2zz coils that would be interesting, im not sure if just tying all the IGF's together to one wire will do the trick or not, would be nice if it did.

Update..kind of. Got motorola sensor connected. Getting exactly 2v to signal 5v to power. Which is weird since they should both be +-.3. Started car and still runs same. Rich eith high idle and won't rev past 2400 rpm give or take. Starts sputtering. Check engine light is on while starting/driving but doesn't come on with key in on position and engine off. So i put old ecu on to check it. Check engine light just flashes constanly. I didn't try to start like this but ecu is at least showing something.
Any advice? I'm running out of Troubleshooting ideas and am now down to trying a new ecu.

2v to signal is pretty much correct for that map sensor. I was getting like 1.8v on the signal wire.
were you ever able to pull codes from this ecu? it is possible you could have a bad ecu, maybe open it up and take a look? I did confirm with another member that 550's run fine with an afc on the aristo ecu, so there is something definitely wrong that was not solved by changing map sensors. it could be the afc settings itself it is still in the loop, the ecu going bad, or even a faulty or stuck injector.
have you used the 550's before and if not and they are used did you get them flow cleaned?
they also need to be high impedance.
If you had stuck to 440s and no afc at first we would have probably figured it out by now, and you could have upgraded after that which would have made troubleshooting much much easier.
oh and on another note, with my 7M CPS, I could not get the car to start, it really sounded like it wanted to but rpm's would only get up to 100 or 200 or so. I tried swapping the G1 and G2 with no luck, couldn't even get it started. might be my cps or the fresh rewire, but from my results it appears the stock distributor is the only way to go.
popped the distributor back in and it started right up.

Some help with finding the right jdm TT ecu.
Stolen from Aristo Club:
http://clubaristo.net/forums/showpos...2&postcount=31 + Random google results.
Aristo ECU Part Number:
- 89661-35060 (91-93)
- 89661-30870 (93-97)
Supra ECU Part Numbers (Auto, J-Spec, NA):
- 89661-14600 (93-97)
- 89661-14810 (97-99)
Some more jspec ecu #'s
Supply various ECU for Toyota all series:
Supra ECU Part Numbers (Auto, J-Spec, TT):
- 89661-14490 (9305-9310)
- 89661-14491 (9310-9605)
Supra ECU Part Numbers (5Spd, J-Spec, NA):
- 89661-14610 (only number listed)
Supra ECU Part Numbers (6Spd, J-Spec, TT):
- 89661-14500 (9305-9310)
- 89661-14501 (9310-9605)
- 89661-14770 (9605-9709)
- 89661-14830 (9709-)
Aristo ECU (JZS16#)
- 89661-3A470 (9708-0007)
- 89666-30180 (0007-)
From what I can find it seems that both Denso 175700-3422 and Denso 175700-3423 = Toyota 89661 30560 which is the 91-93 Aristo ECU

Thanks for a quick reply. Am a start my project soon. I have a hks vpc & gcc. Can those be used. Am aiming for 500-550 hp with my t61. Have hg, studs, wg, bov,turbo manifold,jdm tt ecu,intercooler n piping. Am I ready for boost. I have a super charged 350z to give bus lengths too.. lol
