2JZ swapped BRZ ...
 

Hi guys,

Im new on the forums, just got a blown brz and it was the perfect home for my 2jz-gte making 600whp on pump gas ...

I bought a chase bays wiring harness which we altered alot to make most things work..

After 2 days of wiring and rewiring everything correctly, I cant get everything to work properly ..

Few things like
-gauges.. Iknow this car has gauges running CAN bus, is there a way to bypass that and rewire gauges to the sensor directly ? tach ? H2O ? atleast

-the most important aspect, THE STEERING WHEEL AND RACK, I lost electric steering and ABS ..although speed works so abs sensors are reading, the steering is very heavy and does not work, is there a way to make this working manually ?

Ill post some pix abit later:party0030:

some pix of the build

@Chase Bays

This is an email I got from Ekanoo's tuner back in July:

"We utlized the stock ECU to provide all the standard functions. We acquired EcuTek to disable all the DTC faults and alter some of the parameters. The trick is to get the Crank, cam, coolant, and air inlet temp reading of bothe the standard and AEM ECUs. I used AEM series 2 to run the engine. "

The chase bays wiring i got runs both ecus too...i bought it Thinking the car would run like stock or close atleast but its far oem..the steering doesnt work..the gauges dont work except speedo which is useless..i contacted them nurmerous times n i only get a short reply every few days and cant really do anything..might just swap the steering rack to something else

Not looking good for me....

I posted in the other thread after I realized your location and actual car(gt86)... So I'll restate it here...

As for the @Chase Bays harness not working 100% plug and play for you, I'm going to go on a limb and say it's VERY possible that the pin out for YOUR gt86 is slightly but notably different than the pin out for the USDM cars in which chase bays bases their harnesses from. However, I'll be able to verify it this upcoming month for you.

Just curious, how many things did you have to alter? Not doubting you rewired anything wrong but did you double check everything? Are you able to pull any error codes from the car?

My backup solution if the electric rack setup fails, I will simply go with either a SC300/400 or S14 steering rack and OEM 2JZ power steering pump. Both parts have adequate space to work on our chassis and the rack may require some minor adjustments. As far as the ABS setup, EKanoo and his team got the factory ABS to work with an aftermarket standalone (AEM) and I am sure we can figure it out together or pull resources to find a solution.


Even though we are going the route with ProEFI, I am confident it is the same concept and we'll see. I am still a month out before I start on the wiring process. For the interim, I am on the edge of my seat waiting to see how the harness works with your car and Omar's. I know Omar said he is still a few weeks away. When do you plan on getting to your wiring Alex?


.

I'm putting things together now, but it's going to be next week - possibly the week after that - before I do wiring. Still waiting for a few things to come in the mail (clutch setup, FullBlown pump setup, etc) but I got my ProEFI, CAN display, and a lot of my AN stuff come in the last few days. I'm anxious to get it started because that's the big push point for me. Just to hear the sound will put me over the top. After my fab guy gets here and starts his part, I might take a few days off work to get this thing going quick. If it isn't snowing before the car is done, I'll be driving it.

Out of curiosity when did you order your FBM 485 pump setup(think you said you were going that route iirc). Curious as I still haven't ordered mine but likely will today or this weekend. Hoping that's not what I get stuck waiting for

I ordered it earlier this month. It should be here today I think. When I ordered it, I ordered it outside their website so I think my order slipped through the cracks, but I contacted them a few days ago and they expedited it to me. No worries... I don't think you'll have any wait time.

how much is the Fullblown kit,, ? does the price include everything you need to convert to return fuel system ? and single pump ?

It was $359 for myself. Return style, Walbro 485 pump (E85 compatible).

It's a decent kit, kind of finicky installing it, though.

so 359 including the fuel pump and everything I need to convert to return style ?

Does it not leak ? sealed properly ? no fuel smell ?

It'll be a few weeks before I start the car up but it seems alright at the moment. There's a CNC'd spacer it came with and I couldn't get the pump installed with it on, I emailed @FullBlown to see where it goes exactly :x

Talked to chase bays and they told me to check the can wires that connect from the aem to the oem brz they werent connected ..so connected played with them and got the power steering and abs to work but the key security started to blind yellow instead of green ..all the gauge lights sent off n they keyless entry stopped working lol

One step closer, my friend! If it were easy, it would just be 'the way'.

Just as I suspected.

The mistake is chase bays not mine..im correcting what was supposed to be plug and play :)

Thank you for clarifying @rh9

@Chase Bays - Can you tell us what all needs to be modified?

@slicktop, @OmarGC, and I are about to install the CB harnesses into our cars and do not want to run into the same issues as @rh9. It is also good for others to know what to look out for.

In the next few weeks I should know what's up.

@Chase Bays

Time permitting I guess I'll find out early Dec lol

Thanks for the heads up on this folks. There is no reason for this to blow up or get into "he said he said" stuff. We've been doing this since 2007 so we can solve this no problem. The issue is already clear.

I've been slow at replying because I was in the hospital with a partially collapsed lung. Although I have other knowledgeable guys in house I am the only one that can provide tech support for this. We let customers know there would be a delay, just doing my best here in what I'm dealing with.

With different CAN signals and multiple DTC's popping up, you're going to have some funky issues. Electronic Power Steering/EPS relies on ABS/Vehicle Speed CAN signals in order to function properly. This setup needs ECUTEK to turn off those DTC's and functions This setup needs ECUTEK to turn off those DTC's and functions as well as immobilizer "lock outs". We asked for codes to this customer but he said he hadn't checked them because he didn't have ECUTEK.

I suggested that he get ECUTEK but nothing was said back. I know there was a misunderstanding on our part because I told him to hold out until he tried something I instructed. He did it and it worked to fix the EPS and ABS but he still had some other issues with the key lock out/immobilizer. The fact of the matter is, you've got to get ECUTEK. I apologize if this wasn't made clear on our site, but its bold and at the top of the FR-S/BRZ to JZ product description on our site.

Don't know why I hadn't seen that before. Here goes another few hundred $$$. Gotta pay to play!

Lol I sold my ecutek cable before buying a harness... Welp

I connected the aems CAN H wire to CAN H on the brz oem ecu and CAN L was grounded and EPS AND ABS worked ..but the immobilizer stopped working

I bought a racepak dash to the oem dash isnt as important now, I need need EPS AND ABS and keyless entry and the rest is sorted ..

is there any other software to read and clear codes ?

Get well soon. Thanks for taking the time to update the thread.

Any new updates with your car?

I spoke to chasebays and their last email was to try to twist the 2 can wires from the aem to the oem brz ecu, that didnt work

So I finally kept the CAN H CONNECTED from the aem to the brz ecu and CAN L to the ground, this way the EPS works/ABS and the keyless entry worked somehow lol

the gauges went off but that doesnt matter anymore as I have gone with haltech RACEPAK dash

thats it

Thanks for the update! A few of us are about to install the harness on our cars. Within a week or so, Alex should give us some of his feedback as well.


@slicktop @OmarGC

Yeah, I started wiring last night. It won't be until next week that I start up, but I'll keep you guys posted on what I find.

Would love to know what everyone else is doing with their harnesses...let us know plz and post some pix
