7MGTE + adaptronic. . how much of the factory crap can you get rid of?

[boxh34d]

Yeah, I settled on the Adaptronic purely because it provides good bang for buck, and like has been said, is going to provide all I need on my 7M. Also, my mechanic / tuner has done a couple of them, and likes them. (He is also a trained motec tuner)

[JustCallMeOrlando]

Adaptronic is low cost because it's an emerging product and hence has features of a higher end ECU at a lower end price, offering much better bang for buck than pretty much anything else. One has to keep in mind it's not quite a fully mature product yet....

I wouldn't say it's that immature, some of its features are arguably more competent than some more expensive ECU's, in particular the auto-tuning and knock sensing which sets it aside. When my wideband was setup, auto-tune worked brilliantly and the knock sensor worked great. Most of the initial problems have been sorted, it has 3 ignition outputs and has so for a long while, with some models able to use 4 outputs. The major issues with tuning that Dave from SAS noted when tuning my car I got Andy to fix

The tuning software is quite nice to use as well, very intuitive, haven't had to resort to the manual since it was wired in.

just a bit of a thread dig, are the reccomendations here about waht can/cant be removed for manual or auto ECUs. I plan to go adaptronic on my mz21 but retain the auto box and hopefully airbag control/

comments?

[CrUZida]

You'll need to retain the factory ecu and the auto ecu if you want factory autobox shifting.
Or you'll need a fancy box of bits to communicate with the factory auto ecu.
Or you'll need a complete aftermarket auto ecu.

[Kedderz]

I assume factory ecu will also be retained so the dash can also work.

I am a little confused however bare with me ;
- Adaptronic will take control of spark/fuel/ign maps via the aftermarket sensors and dumb ignitor
- stock ecu will need its connections cut to things like iscv,fpr vsv etc, but what sensors does it need to maintain in order to not throw CEL and other codes and make other things not function.

Sorry if this doesnt make sense Im trying to get my head around it.

[CrUZida]

The dash runs off sensors, not the ecu.

Factory ecu will only need to be kept because the auto ecu needs L1, L2, L3 in order to operate properly.

Apart from that the factory ecu is not required.

If you make a box of tricks up that will convert the TPS signal to L1, L2, L3 then you can ditch the factory ecu. But thats only if you want to use the factory auto ecu.

If you want to ditch the factory auto ecu and go aftermarket auto ecu, or use one of them shift boxes, then just ditch both factory ecu's.

To keep things like ABS and airbag suspension working you need to make sure speed sensors are kept, and and shifter position inputs are kept. I'm 99% sure these have nothing to do with the factory engine or auto ecu's. But you may need to rewire things to get them working.

As for the CEL, unless you keeping the factory ecu controlling everything (and just use the adaptronic to control ignition/fuel), then just ditch it. Either disconnect the wire going to it, or remove the globe.

As for any climate control and AC stuff, I wouldn't know.
No doubt something will require rewiring/relays to work.

[Kedderz]

Thanks mate, very informative + rep

[toymotorsport]

im also verry interested in this subject as im going microtech and if i can wanna keep my bags for now till i can save for coilovers and wanto keep my climate controles working

might haveto do some colaberation on info kedderz

and im stock auto 2

[RyleyMA61]

haha i'm also interested as ive just scored a haltech e11v2.... i want to know if i can use the stock iscv and whether i can use the fuel and ign maps from a base 2jzgte map just to get it running??

will i require to leave the stock 7mgte ecu in the ma61 setup to control ancillaries or can i piss it all off and use the haltech?

[CrUZida]

Piss off the stock ecu Ryley, the MA61 doesn't use it outside the engine.
The MZ20 however may use it for a few things.

As for the ISCV, see if the Haltech can control a 4 wire PWM jobbie, if it can't, no go.

In regards to the 2JZ maps (assuming you can't find a 7M one anywhere), it depends.
It all depends on how the owner wires it up.
Factory the 7M has 3 coil packs and runs wasted spark, the 2JZ has 6 coil packs and no wasted spark.

Injectors on the 7M are 3 pairs of 2. I'm not sure on the 2JZ, but I guess its 6 individual feeds.

Everything else though should be the same or close enough.
Its just a matter of finding someone who has set up the ignition/injection the same way you do, and then making sure wire yours identically.

[RyleyMA61]

sweet thanks cruz, most appreciated

ive read the manual front to back- pretty sure it can control the 4 wire pwm output, which is good.

im wiring mine up wasted spark as per factory setup (eventually to go true direct fire w/ coil on plug or similar)... so i'll set that up correctly and just attempt to use the fuel and ign maps...

going to buy the loom first and copy the factory one before i install it, then go from there... and hopefully copy someone's elses for reference. should be ok though been doing a lot of electronics at uni...

going to also play around with the launch control aspect of the anti-lag system

everyone on the haltech forums basically responds with "yes you COULD, but im a dealer and you should buy a new unit from me"

wankers haha

[M_M]

hi all!!

i know it's an old thread but....

just wondering what other problems you guys have experience while converting to the 7mgte? it's going in a hilux btw.

what do i need to be prepared for? i tried to pm a few people but still waiting for a reply.

was gonna go with adaptronic too has anyone had any major issues with them?

thanks

[boxh34d]

The main issue we had with the adaptronic was the 8 outputs. The stock ISCV takes up 4 from memory, so there was not a lot left for the other shit like the thermos, boost control, fuel pump etc etc.
We were able to get everything that we needed though, and it's working well.
Very happy with the unit itself, though I have never had another aftermarket ECU to compare against. My mechanic / tuner builds a lot of cars and tunes race bikes, and is very impressed with the quality, usability and power of the ECU for the money.
We used the stock engine loom, and cut up an old ECU for the plugs, to make a short adapting loom the then go to the adaptronic. Nice and neat, with a surprising little amount of assing about.

Edit, forgot to add, ignitor need to be changed ( i can't remember whether this was listed further back in the thread ), but we reused about everything else.
A/C works, and on the whole, it starts, idles, and runs a shitload smoother than the factory.
