Pro EFI StandAlone ECU

[suprarick]

Would just getting a proefi 48 (map setup) be better that buying a fuel controller, boost controller, lexus afm, and all that other stuff just to get a 7mgte to boost 18psi without fuel cut and other issues?

Also, is the proefi 48 a plug and play standalone? Meaning, is it easy to install?

Can I use the proefi 48 for the 2jz later on if I keep the 7m electronics?

I'm thinking of just saving the extra money and getting one of these that I can tune myself. I'm not sure if the proefi 48 has its own boost controller or not. Anyone have an opinion?

You can't use the 7m ignition setup if that's what you mean by electronics. I just wired up a 48 on my 7m a few months ago its really simple.

As for the boost control you have to buy a solenoid($100) and then you can control boost via the 48. It's an amazing system so far very well worth it IMO.

I'm assuming its easy to swap over the ignition?

Also, with the proefi 48 is it plug and play and easy to install? Is it easy to tune by yourself or did you feel you had to get an already experienced user to start the car up and tune it?

 

[jg5899]

Yes very simple all you need is to run a trigger to your new coil setup. I went with a 1zz coil setup, 1 coil per plug. You should read up on them they're very good coils thus far.

As far as tuning it wasn't very hard to get a base map up and running, Proefi and whoever you purchase it from will provide all the support you need. Of course getting it tuned by an authorized dealer will yield best and safest results.

Have you guys got the tach working on the stock cluster? Just got the car back from being tuned and need to get the tach working. Any input is appreciated thanks.

 

[Albert]

Yes there is a Pinout for tach. Send it to your body connector for your cluster

 

[Albert]

Pin J1 A22

 

[jg5899]

I have it to that pin, just couldn't figure out the settings. I'll have to double check the wire, i'm beginning to dohbt my work maybe it's not even the tach cluster wire.

 

[Albert]

Should be set to 3 pulses per rev and 50% duty cycle.

 

[jg5899]

I have that a shot and still nothing. It is the black wire on the 11 pin grey plug correct? I tried double checking the tsrm but couldn't find anything. Ill have to trace it back from the dash tomorrow I suppose.

You could run the DH61 igniter from my writeup since it is a simple 3 channel smart igniter, and has an output that is compatible with the mk3 tach.

 

[Albert]

Why when the proefi can do it. Mine works and so does 6+ mkiii supras on proefi. Sounds like a bad gauge/cluster or wrong wire

I wouldn't want for get rid of my 1zz coil setup though. And adding a component when the Proefi is capable is a little pointless tbh.

I'm almost certain it's the wrong wire ill have to check tomorrow though as its pouring atm. The input is greatly appreciated though thanks.

Ok so I got my tach working no problem turned out that pin was loose on the connector.

Now I'm helping out a buddy get his tach working, similar setup except he's running a 48. Does the 48 not work?? Albert do any of the guys running the Proefi on a mk3 have a 48?

 

[Albert]

Dustin is running a 48 along with Tyler

 

[HENRY SIEMON]

Thats mean that I can used the multiplex
System that we have on a 7mgte mk3 whit the 48 ecu???

 

[jotech]

Nope you can't you need to use 6 individual coils,i use 6 2jz TT coils whit the original igniter from a MK4.
For me the best ecu in the world pro-efi

 

[Mr Bojangles]

I just got these coils in the mail to run with my 128 and they are outstanding. If you're running a 2J and Proefi, these things should be on your car.

[Albert]

Rather run 1zz coils. Cosmetically look better IMO. Same concept tho

 

[Albert]

Plus I know someone who killed their engine on lq9s on proefi running the lq9 dwell specs!

Don't run 4.0ms+

I'm running 2.0ms on my 1zzs
