Djaniero Posted May 21, 2019 Share Posted May 21, 2019 (edited) Hi guys, I've just bought an ME221 for my GT, and starting to get bits and bobs to prep the car for a remap. I want to buy a 3 port boost control solenoid to connect to the oem Hi/Low Boost control. To my knowledge, the oem boost control solenoid was ripped out a long time ago, so I was just wondering how I would plumb/wire in a the 3 port to work with the stock boost button and the ME221? Thanks Edited May 21, 2019 by Djaniero Quote Link to post Share on other sites
RobSR Posted May 21, 2019 Share Posted May 21, 2019 The button is a switch input to the ECU so technically has nothing to do with the boost solenoid itself. I use the button to switch boost tables on the Link ECU install's i do. The ECU then outputs the PWM to the boost solenoid from a separate pin on the ECU. (CON-1 Pin 15.) Ive not personally used an ME221 but as its sold as PnP you'd hope they have kept this functionality. But yes you'll need your original boost solenoid wiring for a PnP solution. If its been ripped out, +12v to one side of the solenoid from EFI circuit, other side to CON-1 Pin 15 on the ECU is how its done in stock form. Quote Link to post Share on other sites
Djaniero Posted May 21, 2019 Author Share Posted May 21, 2019 Its still all connected on the electrical/cabin side Rob i.e.I can still press the boost button and I can see the green light go on and off on the dash. I think its the original solenoid that was ripped on on the engine side, when my mechanic did my td04 conversion. Quote Link to post Share on other sites
RobSR Posted May 21, 2019 Share Posted May 21, 2019 Yes for sure, but that still doesn’t signify it’s connected to the ecu. The ecu doesn’t control the dash control logic and led illumination. If it’s ripped out, re install how I said above Quote Link to post Share on other sites
Djaniero Posted May 21, 2019 Author Share Posted May 21, 2019 Thanks Rob. Is this simple enough to do - I'm pants with electrics - or should I just hang fire and wait for the remap and ask my tuner to do it? I've running a td04 setup with all supporting mods below fuel cut atm. I was just going to add some rx8 injectors then get it remapped. You can download base maps off the ME website from what I can gather, but will the car be ok to drive to the tuners - depending on what afs I'm getting on my wideband?

RobSR Posted May 21, 2019 Share Posted May 21, 2019 It’s pretty simple, but if not yes you can ask your tuner to do it. As it’s a VE based ECU, technically you can just update the injector size in the calibration to the CC of the RX8 ones, however I would still wait to fit them until you’re at the dyno. You can download basemaps, last time I checked the firing order, engine cc and stock injector cc was wrong amongst other things so I wouldn’t assume it’s a complete good to go calibration. If its TD04 under fuel cut, you could drive to your tuner on stock ecu, then fit the ME there when on the dyno and do it all in one go. Quote Link to post Share on other sites
motorsport-electronics Posted May 22, 2019 Share Posted May 22, 2019 Hi Rob, basemaps are from running cars - can you let me know stock injector and engine CC and will update this for our next round of basemap egeneration Quote Link to post Share on other sites
motorsport-electronics Posted May 22, 2019 Share Posted May 22, 2019 ECU uses stock boost switch as a digital input that yes, can switcvh boost maps if you want it to Quote Link to post Share on other sites

RobSR Posted May 24, 2019 Share Posted May 24, 2019 Personally I wouldn’t skimp on a map sensor as it’s one of your main control sensors. Expect to pay £80-£120 for a good one. Quote Link to post Share on other sites
daniel_g Posted May 24, 2019 Share Posted May 24, 2019 If you want a second hand map sensor i have a Toyota ST205 3 bar map sensor i'll sell cheap, i am not using it. That used to be the done thing back in the day on a Starlet. I went for a 4bar Link one. Quote Link to post Share on other sites
Djaniero Posted May 24, 2019 Author Share Posted May 24, 2019 Are they definitely 3 bar? I remember reading a post some years back on TGTT.com about them being more 2 bar than 3 bar sensors? Quote Link to post Share on other sites
daniel_g Posted May 25, 2019 Share Posted May 25, 2019 Not 100% sure. It came off a GT i now own, it was a TOTB winner a few years ago. You are probably best off buying a new one. Quote Link to post Share on other sites
Djaniero Posted May 25, 2019 Author Share Posted May 25, 2019 A mate of mine has one on his GT running a Power FC. He said they're more of a 2.5bar map sensor....which will be fine for my needs. Can you tell me what the part number is and how much you were after for it? PM me if its easier. Thanks Quote Link to post Share on other sites
daniel_g Posted May 27, 2019 Share Posted May 27, 2019 949940 - 6270 is the part number. Quote Link to post Share on other sites
Devs313 Posted May 27, 2019 Share Posted May 27, 2019 (edited) Are these as reliable as 3bar Map Sensors? Edited May 27, 2019 by Devs313 Quote Link to post Share on other sites
Djaniero Posted May 27, 2019 Author Share Posted May 27, 2019 Can you see any other number under the number you gave me? It should start with 89. The part no I have is 89420-17050. Quote Link to post Share on other sites
daniel_g Posted May 28, 2019 Share Posted May 28, 2019 Maybe this isn't a GT4 sensor. All I know is it was the map sensor on this GT I am rebuilding. Its a black MK2, white bonnet, was running well over 300bhp, it won the TOTB a couple years. Fella called Mike owned it, there might be a build thread. Quote Link to post Share on other sites
Djaniero Posted January 6, 2020 Author Share Posted January 6, 2020 Thread revival. @RobSR @motorsport-electronics Can either of you tell me which ports on the ecu, I need to run the 3 port boost solenoid wires to? Thanks Quote Link to post Share on other sites
RobSR Posted January 6, 2020 Share Posted January 6, 2020 As it’s a PnP I presume ME made it to run with the stock wiring? I don’t map ME so they’ll need to confirm. If so, remove your stock solenoid and replace with the 3 port. Doesnt matter what way round you wire it. One side is 12v from EFI relay other side runs to ECU If wiring has been removed, go with what I said in my original reply at the top as that’s how it’s done stock.

Djaniero Posted July 26, 2020 Author Share Posted July 26, 2020 (edited) Hi guys, I plugged my ecu in today and tried to download a base map.However there is no base map on the me221 site for a black board gen1 ecu, only the white board ecu. Anyone have any ideas how I can get around this or do ME need to update their basemaps? Thanks Edited July 26, 2020 by Djaniero Quote Link to post Share on other sites
