I'm having an issue with my BEE-R rev limiter on my 89+ supra 7MGTE. the damn thing just doesn't seem to work correctly. i have tried wiring it in numerous configurations and the only one that yields me a partial result is the configuration from this link which is JZA70 specific:

http://www.supramania.com/forums/sh...v-limiter-Installation-Guide-(JZA70-specific)

i currently have it wired into the ECU in the configuration from the above link which is:

Red wire - +B

Black wire - Battery ground

Yellow wire - NE

Green wire - IGF



right now the rev limiter works however it is rev limiting at idle (bouncing idle from 650 rpm) it will not let me go past 1000 rpm on any setting, on any knob. when i put the yellow gain knob back to zero (0) the rev limiter deactivates and runs as if there was no BEE-R installed, which is what it's supposed to do. i have also tried to intercept the other 3 igniter wires which are IGT, IGDA, and IGDB and all yielded the same results above. also tried wiring the way the BEE-R instructions say to do and i got zero results.

i need some help from someone who has installed one of these on a 89+ 7MGTE. i know there is a few guys out there that have these installed because I've seen the videos on youtube! i just need some direction on how to wire this thing up! thanks!

It's been a long while since I wired mine up so I can't remember perfectly.

Perhaps try another ignitor posiition on the ecu? Is the unit new, are you certain that it works properly. Mine started failing a little and I have to squeeze the unit for it to work....

Also have a look at this thread:

Thanks for the input man. Ill try to squeeze it tomorrow lol. I tried all 4 of the igniter wires going to the ecu and they all yielded the same results. The unit is brand new. At least it looks that way. Wires untouched... even wired it for a 3sgte, jza70, iggte, and the 7mgte and only the jza70 way has partial results. but I went to bee-r's website and it says there's a counterfeit model of their unit on ebay (which is where I got mine) that has the wrong microchip in it which causes it not to work correctly. Also says all new models now have a placard with a serial number, mine has no placard... I'm gonna continue to mess around with the unit, different configurations etc, and see if I can get it working. If not, gonna try to get another unit. Again thanks for the input!

The link you posted above shows the yellow wire going to IGF(RPM) and the green wire going to NE(Ignition Signal), yet your post states they are hooked up opposite, was this a typo? Also, there are three loops of wire(grey, white, brown) at the base of the unite where the wire harness comes out. Verify that these three loops are all intact and NOT cut.

Dirgle, I hooked up the unit that way as well and the unit didn t even turn on, rechecked all connections and tried again and still didn't come on. I read on some other forums on how guys were hooking it up and they are doing it the way I have done it. I even went as far as opening the bee-r unit and each wire is labeled inside the way I have it wired up lol. I tried about 10 different configurations. I'm starting to think its the unit itself because the seller on ebay is issuing me a full refund.... we will see though

*UPDATE* i tried a few more configurations and still nothing. i even wired in the white wire for the E-Brake to see if that would help and..... NOTHING! the lights start flashing at the right time but it's not cutting spark at all. i contacted another seller from ebay about the issues that I'm having and he said to open up my unit and see if the knobs are attached to blue switches. if they are, it's a counterfeit unit. if they're attached to black switches, it's a genuine unit. here is what mine looks like:

mine are attached to blue switches, which explains the issues i'm having. FAKE UNIT! I purchased another unit from the guy that i have been emailing back and forth and am getting a full refund from the previous seller. the new seller is willing to work with me and give me a refund if this one doesn't work. he also verified that the knobs are attached to black switches prior to it shipping so this should be a genuine unit that works, i hope. so Bee-R purchasers, check your knob color before you purchase. don't want anyone to go through what i am going through. More updates to come as the new unit comes in!

*UPDATE*

Got the new unit in yesterday and got it installed. unit works as advertised! definitely got a bad unit from the last guy i bought it from. i can definitely tell a difference from the build quality. the unit is heavier, the wire loom looks cleaner and the switches actually make a click when you turn them. and the knobs on the new unit ARE connected to black switches.

i wired it the way the directions tell you to for an 89+ 7mgte and it did not work. I ended up having to wire it up the way the 3sgte says to do it. RED is the way that didn't work and GREEN is how I have it wired on the below instructions:





current working setup is as follows:

Red wire - +B (black w/red stripe wire on ECU connector)

Black wire - Ground (anywhere to the chassis)

Yellow wire - IGF (Turquoise w/black stripe wire on ECU connector)

Green wire - NE (Blue wire on ECU connector)

White wire - E-Brake (white wire coming from E-Brake light switch)

I'd imagine it would go the same way for the 87-88 ECU just make sure you're tapping into the ignition and RPM signal wires (IGF and NE) respectively. 89+ 7MGTE guys, here is the way you wire this thing up! i hope this helps and works for anyone else who is trying to do this.
