Thanks Rob. Ill give it a look. What i dont understand is that the NA ECU didnt have an ABS wire. So in theory nothing has changed by not having it hooked up to this ECU.

Ah yeah my bad. What I said is probably not relevant then, unless there was another wire from the ECU to the ABS (but not labelled as an ABS wire).
Have a look at the BGB anyway, try to find where the signal to the ABS light on the dash comes from.

I found this wiring diagram which i assume is relevant to all engines.
Pin 15 seems to travel to ECU for the 3sgte only. Other than that it doesnt seem to interact with the ECU at all for other engines.

Did you check the ABS fuse?

Sure did and its all fine. I also check for codes and its just producing a solid ABS light which means there is a malfunction at the ECU which i find very hard to believe. I might try running this wire to the ECU and see if it makes a difference.

The final cost is dependent on the condition of the half cut and whether or not you can do the work yourself and where you can get it from. I know when i did a rebuilt NA motor; toyota quoted me 2k in labour for the engine drop/replace. So far for the halfcut it self was 4.2k delivered from WA. Then in parts which has included a rebuilt turbo, boost controller etc has equaled 2.4k. Since then i have stopped counting but im around the 7k point at the moment. I still have a tune up and blue slip/change of details bill to come yet. 
 
Im sure it can be done for a lot less but that is assuming the halfcut is pretty much in A1 condition or really you could just sell up and buy a good condition MR2 Turbo for the same price. Though the reason I stuck with my MR2 is because i know where mine is mechanically and i didnt want to buy into more problems.

Congrats on getting it up and running! Once you have the boost controller dialed in I think you'll enjoy the power increase over your previous NA.

I just found this for you.

It's a how to guide for pulling the ABS fault codes and what they mean. Should get you out of trouble.

I was at MRC for most of today, while they worked on my car.
I also saw yours while I was there:

 
As Mark told you on the phone, I think your car made something like 153rwkw at 11.5psi, which is almost exactly what it should be making :-) I heard him talking about the boost control issues though.
Mark told me about the problem with the rear ABS ring which explained the ABS issues hahaha.

Thanks Rob for the photo! Wish I could of been there for it. 
 
I must say i am a bit disappointed with the result since it is a tad low on power and mostly for the fact that my brand new boost controller is faulty. From what i assume it was only working off the wastegate actuator spring pressure? I have contacted the manufacturer of the controller to get a replacement. 
 
Mark also mentioned that the engine was running a tad lean at the bottom end but was running a normal rich ratio up top. Not sure yet if that is something to be concerned about until i speak to Mark tomorrow morning.  
 
Nonetheless she passed her blue slip which I'm very happy with and am looking forward to when i can get a working boost controller and get her dialled in properly.
 
As for the ABS issue with the ring. its not going to solve the problem entirely as after checking for codes there is an issue with the ABS computer itself. Which i can assume will have something to do with the wire that needs to be connected between the ECU and the ABS computer.

That 153RWKW at stock boost is pretty good man. You should be up around 190-200 at 17psi with your tuned ecu.
 
Another thing, I think that lean spot just as you come onto boost is a gen 3 ecu trait. They all do it from the factory.
Have a search on MR2OC about it?

Knowing that it is running below the stock 13 psi; I can't complain as it is pretty good for what it is. Will be awesome when the controller is setup. But i am very happy with how much torque it has. I'll post up the dyno sheets tonight when i get home. 
 
Well thats good to know. Though i was told that maybe i should look for a stock ECU to see if it changes. It is running lean at 17.0 around 3k RPM, it then sinks to around 14.5 just after 3k and settles there till after 4k where it then slowly gets richer and finishes just below 11.0 at 6k.  
 
Also spoke with the engineer at Go Fast Bits today in regards to the issue with my boost controller. He showed me how to recalibrate the controller and it now seems to be working correctly. I plan to have the car booked in at MRC next week to have it set up properly.

If it helps I have a stock gen 3 ecu here that I borrowed off Darius on the forum to see if my own gen3 ecu had any problems. Maybe send him a PM and see if you can borrow it to try it out?

Here is the dyno sheet from yesterday. 

 
The boost controller is definitely fixed. It was accidentally set for 20psi which I know is not good for the 20b and I have dialled it back since then. But wow! 20psi is exciting. She has been booked for another session at MRC for this coming Monday.
