TrisK Posted February 4, 2014 Share Posted February 4, 2014 id rather get the ecu running on my car than have to go back to square one and find another one!, just wondering if anyone has anything i can try to see if i can get it working? The wire thing is specific to the hrf ecu designed only for the mk1 gt ive read. Its a PLUG AND PLAY ecu so why would i have to cut my loom? Its been sold to me as tested working on a mk3 quadlight ep82 so unless my car has a one of a kind loom i dont think its going to do nothingl other than risk causing damage to my car! And also in no post on here have i said im willing to try "anything"Because although its a plug and play. the looms and ecus are different accross the 3 models, have you got a photo of the model code on the ecu?

Sandham Posted February 4, 2014 Author Share Posted February 4, 2014 On the mines one? Whereabouts will it be please? And yes i understand that but ive been told it was tested on a mk3 quadlight from the same year as mine!! Quote Link to post Share on other sites
triple j Posted February 4, 2014 Share Posted February 4, 2014 Get a stock fpr and try or drop your fuel pressure below stock, a plug and play will be rich and it could be over fuelling and bogging it out on start up, u could also try check for codes, if not try the wires around it will only take a few minutes.

And yes i understand that but ive been told it was tested on a mk3 quadlight from the same year as mine!!There will be a sticker on the ecu, the number will start 89661-10*** From both the mines and your standard ecu Quote Link to post Share on other sites
_shaun_ Posted February 4, 2014 Share Posted February 4, 2014 am miles away in scotland so post is only realistic way ha. personaly i wouldnt touch my loom id see if you can find someone to to test it on there car. even if its a bit of a trek id rather spend 2 hours driving that dick around with loom wires so close to the ecu.

Fizturbo Posted February 4, 2014 Share Posted February 4, 2014 I would of been up for meetin you half way,am roughly 40miles away but my car has a complete odd set up Or could try in other starbo if your willin to travel my way cause it's sorn of road. Quote Link to post Share on other sites
Sandham Posted February 4, 2014 Author Share Posted February 4, 2014 The only numbers are 048 and 920227nb on one side and 1237 on the plaque Quote Link to post Share on other sites
triple j Posted February 4, 2014 Share Posted February 4, 2014 I would Dick around with my wire before I would drive 2 hours lol, have u disconnected battery before u swap ecu over. Quote Link to post Share on other sites
Sandham Posted February 4, 2014 Author Share Posted February 4, 2014 Yeah dont want to touch the wiring because i dont feel like i know enough about the loom to start playing with it, electronics arent my forte lol! And yeah i followed amjads guide he put in abother thread on here Quote Link to post Share on other sites
TrisK Posted February 4, 2014 Share Posted February 4, 2014 The only numbers are 048 and 920227nb on one side and 1237 on the plaqueWhats the number for your standard ecu? Thanks Quote Link to post Share on other sites
triple j Posted February 4, 2014 Share Posted February 4, 2014 I understand mate, does it smell of petrol when u try to start, try it again with fuel pressure well down, also check for codes it's no harm. Quote Link to post Share on other sites
Sandham Posted February 4, 2014 Author Share Posted February 4, 2014 (edited) Where will they be on my stock ecu theres a piece of rubber glued to itAnd not particularly mate it turns over really well just wont fire i got one splutter from it but it was barely alive and died immediately Edited February 4, 2014 by Sandham Quote Link to post Share on other sites

triple j Posted February 4, 2014 Share Posted February 4, 2014 To me now it sounds like map sensor reading issue with the plug and play ecu. Quote Link to post Share on other sites
Sandham Posted February 4, 2014 Author Share Posted February 4, 2014 Itll be a probably green sticker on the main face of the ecuAlso does your have this white sticker?Nope no stickers at all on it, ill go have a look at the stock ecu and see what it says.. Will also try winding my fuel pressure down a little bit because when fired the pressure bounces between 2.5 and 2.6ish bar.. And if it was a map sensor wouldnt the car be affected with the stock ecu fitted? As its spot on with the stock ecu Quote Link to post Share on other sites
triple j Posted February 4, 2014 Share Posted February 4, 2014 True but I would check map sensor voltage with the two ecu's, it would rule out if the plug and play is using proper Mao sensor voltage, or maybe there the wires that need swapping, am unsure but am just throwing these ideas out.

Sandham Posted February 4, 2014 Author Share Posted February 4, 2014 Unfortunatley i dont have a multi meter to hand. Ill try the fuel pressure and get my numbers from my old one for trisk then report back Quote Link to post Share on other sites
TurboTobz Posted February 4, 2014 Share Posted February 4, 2014 I've had funny issues with a forum members Glanza and an fcd it would never operate and would run like a bag of shit when wired up.Changed the glanza MAP for a GT sensor and it ran fine with the original map sensor and no fcd it ran fine. Maybe worth trying another map IF you can borrow one. Quote Link to post Share on other sites

Maybe worth trying another map IF you can borrow one.Do you think it's actually hitting fuel cut before turning over, I think for instants running a fcd along with the ecu would make a change? And if it did start you could set the fuel pressure to whatever boost is running just a hunch...I know ecu's eliminate that but I have seen a fcd ran with a plug n play before...or it could well be the sensor Edited February 4, 2014 by Gainzy Quote Link to post Share on other sites
bucketep91 Posted February 4, 2014 Share Posted February 4, 2014 Do u have an fcd fitted to the car? Quote Link to post Share on other sites
Sandham Posted February 4, 2014 Author Share Posted February 4, 2014 Nope no fcd, just refitted and reduced my fuel pressure and theres no difference.. Done diagnostics with the eml and it shows no faults. Quote Link to post Share on other sites
triple j Posted February 4, 2014 Share Posted February 4, 2014 get a loan of a multi meter and check the map sensor voltages. Quote Link to post Share on other sites
Sandham Posted February 4, 2014 Author Share Posted February 4, 2014 These are the numbers on the mines ecuAnd these are the standard onesAnd ill see if i can get hold of one but how do i test it with the multi meter? Getting sick of swapping the ecus back and forth now And surely if its hitting fuel cut before starting that makes the ecu faulty because it runs sweet on the stock ecu...With the mines ecu fitted it turns over really healthy it just wont actually start Quote Link to post Share on other sites
TrisK Posted February 4, 2014 Share Posted February 4, 2014 Is your car an auto? or was an auto? scrap that Quote Link to post Share on other sites
TrisK Posted February 4, 2014 Share Posted February 4, 2014 You did put up a topic here, that your car stuggles to start sometimeshttp://www.ukstarletowners.com/topic/75648-spluttering-help/ So could be something like timing, then the more 'aggressive' map on the Mines ecu isnt good for it.
