ME221 Mx5 Na 1995 Wont Start
Long Story Short Drove my Mx5 Into my Garage and parked it.
Done the build with rx8 injectors, TD04, fmic, IAT, ME221, Avcr boost Controller and now the car wont Start there is no spark at the leads. If I plug in the old ECU to start the car it fires up and cuts out due to the MAF delete which doesnt bother me I know everything in Car is good but whats up with the ECU its brand New ?? |
I would contact ME directly. But it sounds like a blown spark driver or something.
|
Thanks yeah its odd. Contacted them but very slow to respond sent them on a datalog file and Calibration and they havent been back to me yet need the car running asap so I can finish exhaust mapping and get it on the road again...

Try putting a battery starter on your motor.
Past versions of the ME221 were known to not get a crank signal when the battery voltage was too low. |
Well on the ECU it comes up at 12.1V the battery is about 2 months old and was fully charged before I tried starting it so yeah that should all be good :)
|
You may want to launch your MEITE software and take a look at the voltage reading the ECU is getting during cranking as well.
Something to check while you wait for Matt to respond to you. |
Okay Ill try that but it starts first turn on original ECU so I dont know whats going on ill try that and see what I get thanks :)
|
Like aidan said contact ME, I'm assuming you're in the uk because you call it an MX-5. Customer support is supposed to be one of ME's strong points, let us know how those claims stack up
|
Im in Ireland but ya contacted matt got the car started simple wire that had to be connected and it fired up :) :) now to stop it from revving up and down uncontrollably :)

Perhaps you could post the solution to help the next person, so they don't have to contact ME?

Had to connect f/p wire from diagnostics to earth to run the fuel pump the Installation videos dont show it Online .

Jumping the F/P and ground is a great way to temporarily test the fuel pump, but should not be left in that configuration permanently. Just for a reference when I built my first MS1 10 years ago, it could control the fuel pump perfectly. There is absolutely no reason why a modern day ECU should not be controlling the fuel pump. |
This is what I was told to do by ME I know its very dangerous and can be heard running all the time if you go onto the ME website_support and go to ME221 hardware install guide 8995 it explains it in the manual to do exactly this.
Any other ideas For this ? Want the Car to be safe too it will be my daily. |
its only dangerous if you run into a tree, really.
If your ECU cant activate a fuel pump, it shouldn't be installed in your car. I remember these guys could barely wrap their heads around the DIYPNP and then they go and developed this gem. I honestly feel bad for ME221 and FM221 users. |
I got one for one of my customers - for very good price.
It was a bad experience and all I found out is that the product was not ready to sell, many bugs, in the fw, software and labeling... http://www.mx5nutz.com/forum/index.php?showtopic=311274 |
you obviously dont know how to tune.
|
Why like this?
All the cars,jeeps and bikes I tuned successfully do not agree with your childish post. Not nice. |

Couldn't tell the sarcasm from here - if there was any.
The ECU had a missing component the support ask me to add... The software had bugs and unfinished functions. It cost the customer more time and money then needed. On the dyno the ecu got totally rested once - good thing I had a tune file saved. For now he does use it and it is ok... (with beta fw and the missing component added) :\ |
I'm interested to see what FM says about the ground issue. If they sell that system and something happens, wouldn't they have some liability? I also can't see them selling something like that since it's unsafe at some level?
Maybe I'm just too optimistic... |

IIRC one of the wires/diodes I soldered on the earlier boards in Colorado was to address this.
While I have no idea what the current FM221 board does, I do know there were many updates/etc. that we made to the ME221 boards over the development period. My guess is that the OP has one of the earlier ME221 boards, which doesn't quite match the current/documented specs. I believe there were two or three diodes/jumper wires that were needed, and that was over six months ago. |

Its a shame all of the UK tuners and now the biggest in the US all use an ME221 based ECU as opposed to a megasquirt based one - the argument of wrapped your head around DIYPNP is exactly its faults - people want an ECU that works, not one that requires a software engineering degree to get running - thats probably why MS fails, well that and its terrible engineering - if you're going to make the code opensource at least *try* to code it to a relatively decent standard.... thats why I feel sorry for all the MS users.... |
