MercuryT Member 53 Member For: 19y 8m 4d Gender: Male Location: Melbourne Posted 20/04/06 08:26 AM Share Posted 20/04/06 08:26 AM For the last 6 weeks or so I had an intermitent engine mis-fire. When I had my EDIT done last week and we fitted new plugs the mis-fire seemed to disappear. Anyway since Monday the problem has returned and seemed to be getting worse! Cold morning starts were terrible, in to netural at the lights and a high idle with the car coughing and spluttering. I spoke with Simon @ NizPro and he advised me to bring the car back and he would look at a few things. We replaced all 6 coil packs, still no good, checked the spark plug gap again, all .08. We put the standard Ford tune back in and the car was terrible, noticably worse than with the EDIT tune in. Anyway, I took the car back to Westpoint who have been doing my service and have had several goes at determing this problem and they said "Sorry, can't look at until Friday week the 28th" That was over 10 days away, the car was running on 5 cylinders, gulping fuel and just being a horror to drive. Not Happy Jan! Anyway, spoke to Simon and he suggested Etheridge in Ringwood, so booked it in yesterday and took the car down this morning. Explained what Simon had done and also that he suggested it was probably the coil driver so they looked straight at the PCM. Did some tests and found the coil driver stuffed, this had also fried #6 coil pack!!! Changed the PCM and the coil pack. The new PCM is a newer harware & software version. This new version then wouldn't talk to the transmission. It kept throwing a code, anyway they ended up downloading the old file from another customers car and putting it in my new PCM. (They couldn't use use my PCM file as the driver was stuffed) The boys at Etheridge did a great job and the car is now beautiful again. So I leave and then try and reload my EDIT. The long and short of it is because the Processor number on the PCM has changed the EDIT needs to be reset!! Just lost a life! Anyway, Dave spends an hour or so trying to manipulate the file to work with the new processor number but the engine is just not happy. So anyway back to NIZpro in the morning for a re-tune!! I will let you know the end result. Link to comment https://www.fordxr6turbo.com/forum/topic/24850-engine-mis-fire/ Share on other sites More sharing options...

It confirms to me that Simon is super switched on with the BA/BF product as he said to me that he thought it was a Coil Driver issue. This turned out to be exactly the problem. He suspects some other cars are affected with this issue but until they completely fail like my car, it is very hard to trace. The problem started very small for me, with only the occasional mis-fire but then went rapidly down hill in the last few days. The boys at Etheridge said that they had only seen 2 or 3 cars with this problem. Anyway, the car is sweet again, looking forward to getting the tune back into it.Catch you tomorrow.Simon Link to comment https://www.fordxr6turbo.com/forum/topic/24850-engine-mis-fire/#findComment-372643 Share on other sites More sharing options...
MercuryT Member 53 Member For: 19y 8m 4d Gender: Male Location: Melbourne Posted 21/04/06 02:47 AM Author Share Posted 21/04/06 02:47 AM So, I had my car re-tuned this morning and the results continue to improve!!The car made a little over 260 RWKW but ran out of injector and valve spring so Dave turned it down a bit and I ended up with 257RWKW. I will post the graphs when I get a chance but the car is fantastic again. Thanks NizPro!!

Posted 21/04/06 02:59 AM Share Posted 21/04/06 02:59 AM that's a great result. Going from your results and the results from guys with BF Typhoons, I'm thinking that the BF Typhoon must have a bigger injector to be able to get around the 290rwkw area with standard injectors.Geea.

MercuryT Member 53 Member For: 19y 8m 4d Gender: Male Location: Melbourne Posted 21/04/06 03:48 AM Author Share Posted 21/04/06 03:48 AM I actually spoke with Dave about that exact issue this morning and he said that they had flow tested a set of BF Typhoon injectors and they flow exactly the same as a T. He had no idea how they are getting the fuel out of them. I am sure somebody will be able to shed light on how FPV are making them work!!

Posted 21/04/06 04:59 AM Share Posted 21/04/06 04:59 AM Not sure but I think the fact that although both the ba and bf run the same fuel pressure the fuel pump it self is a lot different in that the bf pump delivers almost double the fuel pre 10 sec test cycle than the ba pump.This may have something to do with it.Ian Link to comment https://www.fordxr6turbo.com/forum/topic/24850-engine-mis-fire/#findComment-372834 Share on other sites More sharing options...
