Guest BigBob Posted May 10, 2008 Share Posted May 10, 2008 Hiya guys, sorry to be asking questions on my first post but had to pop over from the other side(GTR Owners!!) so don`t slate me straight away! Got a problem and hoping you chaps can help me on it, basically had a muppet of a customer try and put jump leads on his car and connected them the wrong way round! So, checked a couple of fuses and replaced them but at the moment we are getting no fuel priming with ignition and no spark. Took the ECU out to find it`s plastered with MINES stickers so no one i know will look at it. So, if i get a replacement ECU with same part numbers and plug it in will it work or do these cars have some sort of fuel cut in the ECU that will need the key programming in?? It`s a 95 TT auto and not even registered yet as it`s just come in from the docks! Thanks in advance guys and appreciate any help.

Steve Posted May 10, 2008 Share Posted May 10, 2008 Someone else on here did that a few months ago, but i cant find the thread. So you have checked all the fuses in the engine bay and the ones in the drivers footwell? Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted May 10, 2008 Share Posted May 10, 2008 The problem is that you never know for sure what the MINES modded ECU is actually set for, fuel cut definitely, but what else is not known for sure, generally BPU, i presume the car is decatted etc? if it has more then it may be mapped more extensively, but if just BPU then a std ECU should work but obviously you will need to fit a fuel cut defender.

Guest BigBob Posted May 10, 2008 Share Posted May 10, 2008 Cheers guys, i`ve checked all the fuses and they are fine, mannaged to borrow a standard ECU for testing but still getting no fuel, thats why i was wondering if the key needs to be coded to the ECU for an immobiliser cut built into it?

Tricky-Ricky Posted May 10, 2008 Share Posted May 10, 2008 AFAIK there is no code or immobilisation built into the MINES ECU. Quote Link to comment Share on other sites More sharing options...

absz Posted May 10, 2008 Share Posted May 10, 2008 Are all the ignition lamps coming on as they should ? battery/engine etc etc. Quote Link to comment Share on other sites More sharing options...
Guest BigBob Posted May 10, 2008 Share Posted May 10, 2008 yup, all ignition lights on as normal and car turns over, just no fuel Bob Quote Link to comment Share on other sites More sharing options...
Scott Posted May 10, 2008 Share Posted May 10, 2008 I did this with my MR2. Obviously its not exactly the same but i hit the same wall as yourself. Turned out to be one of the engine bay fuses. I think it was the EFI one or something like that. I think there are 2 or 3 sets of fuses in the sup. Some are hidden some are not. Just make sure all the fuses are fine as i doubt it would be anything to do with the ECU. Quote Link to comment Share on other sites More sharing options...
Nic Posted May 10, 2008 Share Posted May 10, 2008 Have you checked the diagnostic codes, see here how to guide here: http://mkivsupra.net/vbb/showthread.php?t=35920 I'm not sure if you can check for codes with the Mines ECU or not, basically the Mines ECU is a standard ECU that has been modified to up/remove fuel cut, up/remove speed cut and has more performance orientated mapping. Member Nick is a Mines dealer based in Japan, he may be able to help with more info. Quote Link to comment Share on other sites More sharing options...
SimonB Posted May 10, 2008 Share Posted May 10, 2008 Check your fuel pump is working correctly by bridging the FP and +B connectors in the diagnostics port in the engine bay and then turning the ignition on. That should run the fuel pump. Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted May 10, 2008 Share Posted May 10, 2008 Could well be the EFI fuses, if you haven already checked them. Quote Link to comment Share on other sites More sharing options...
Jake Posted May 10, 2008 Share Posted May 10, 2008 Might have blown the igniter pack. Do you have access to another one just to test it? It's the flat box looking by the top of the nearside suspension... http://xs121.xs.to/xs121/07463/016ignitorpack.JPG Quote Link to comment Share on other sites More sharing options...
Guest BigBob Posted May 10, 2008 Share Posted May 10, 2008 Cheers guys, few bits of good info there for me to play with!! Much appreciated Bob Quote Link to comment Share on other sites More sharing options...
Mike B Posted May 10, 2008 Share Posted May 10, 2008 if it is a mines ecu (remapped) then it will be useless to you on uk fuel anyway. I had a fcon-S fresh out of the docks and it was a det monster on uk fuel. does it have an immobiliser? good luck with your fuse hunt Quote Link to comment Share on other sites More sharing options...

Guest BigBob Posted May 20, 2008 Share Posted May 20, 2008 Had a play, bridged the connections in the diagnistic plug so no am getting fuel, did diagnostic test and coming back with fault code 14. Did a quick search but not found anything with that code, any ideas?? Bob Quote Link to comment Share on other sites More sharing options...

Rich Posted May 20, 2008 Share Posted May 20, 2008 (edited) The MINES ECU's are fine. My previous car let go melting pistons in chambers 3 and 4 on a mines ecu at 1.2 bar. I had no AFR gauge in there to monitor temps and egt probe mounted in the downpipe .(so no accurate measurement of the temperature) . This occured running on optimax . The car let go on a high speed run on a private road at around 160 mph in 6th gear. This could have been either down to the ecu or maybe faulty injectors.(440cc) I am a bit sceptical about the Mines ecu 's after this.

Scott Posted May 20, 2008 Share Posted May 20, 2008 Sorry but I disagree.My previous car let go melting pistons in chambers 3 and 4 on a mines ecu at 1.2 bar. I had no AFR gauge in there to monitor temps. This occured running on optimax . The car let go on a high speed run on a private road at around 160 mph in 6th gear. Why would that be down to the Mines ECU? Quote Link to comment Share on other sites More sharing options...
Rich Posted May 20, 2008 Share Posted May 20, 2008 Why would that be down to the Mines ECU? apparently the fuelling is leaned off for more power,the ignition map is also a lot more aggressive and the map is for 100 ron + fuel. Quote Link to comment Share on other sites More sharing options...
Scott Posted May 20, 2008 Share Posted May 20, 2008 the map is for 100 ron + fuel. So is the J-Spec so its not that. I didn't know it was mapped lean although i did know it was re-mapped for 1.1 bar Quote Link to comment Share on other sites More sharing options...
Nic Posted May 20, 2008 Share Posted May 20, 2008 map is for 100 ron + fuel. Do we actually know this or is this just hearsay? Surely the ECU will still pull ignition if it detects knock. Has anyone with a Mines, Blitz, TOMS, etc. ECU had their car dynoed and checked the AFR's? Nick deals with Mines so could perhaps find out for sure what changes are made on the Mines ECU.

Rich Posted May 20, 2008 Share Posted May 20, 2008 So is the J-Spec so its not that. I didn't know it was mapped lean although i did know it was re-mapped for 1.1 bar Yeah but the J spec stock ECU probably runs a less aggressive ign. map so would in theory be safer and therefore is less chance of det occuring. the map is not running super lean over this level? Plus if the fuelling is only remapped to 1.1 bar how do we know the map is not running super lean over this level? Quote Link to comment Share on other sites More sharing options...
