GrahamAT Posted August 17, 2014 Share Posted August 17, 2014 Hi all, I am a new member so apologies if this question has been asked/answered a million times. My bugeye STi was remapped following a few mods 3 years ago, it's now not running as it should, it is hesitant through second gear, I was thinking it may need a remap and perhaps the induction filter removing as i believe they are restrictive? Can anyone recommend someone to remap the car? I am based near Chester? Many thanks Quote Link to comment Share on other sites More sharing options...
Jay762 Posted August 17, 2014 Share Posted August 17, 2014 Wotcha and welcome - it is unlikely the map has corrupted of its own accord the ECU's tend to be quite robust. As the car has run fine for a number of years with the map it is probably something else Are there any engine codes that have been generated as this could point to an issue??.. If the car was mapped with the current filter in place I would keep it as is - possibly clean or replace the old filter if needed. When were the plugs last changed? It might also be a coil pack breaking down Check the MAF sensor is working correctly also - disconnect whilst the car is idling - what is the result??

Ash007ks Posted August 17, 2014 Share Posted August 17, 2014 if its not running as it should can you describe a little better ?? parts could have been removed from what the car was mapped with, i have JGM coming to sheffield in September, about an 1.3 hrs drive for you but id highly recommend him. Does your idle hunt i.e go up and down alot ?? if not just clean the induction and maf sensors. 1 Quote Link to comment Share on other sites More sharing options...
GrahamAT Posted August 17, 2014 Author Share Posted August 17, 2014 Hi and thanks for the reply I have emailed JGM today, September is to late for me as I have already advertised the car, Sod's law it's started playing up now. Appreciate the advice Quote Link to comment Share on other sites More sharing options...
