Muffleman Posted July 19, 2006 Share Posted July 19, 2006 One of the reasons we had to abort the higher boost tuning on my car was that the EVC boost controller was under reporting boost, and Gary at gt-art said that there was a fault on it. So it was sent back to Trial, they have returned it and it's the same. These two pics were taken with the engine off: (Apologies for the blurring, but had to turn the flash off) http://img413.imageshack.us/img413/6628/evc002smallts1.jpg http://img413.imageshack.us/img413/3632/evc003smallzh7.jpg What I was told was that the throttle position is showing at 100% all the time (top left of the EVC), and this is wrong but couldn't be cured by a reset. Also, even when off the boost flutters between 0.00 and 34mmHg (pic 2) and the revs flutters between 00 and 33000rpm. When driving, the throttle position stays at 100%, and the revs is usually at 15000rpm. (I wish ) I'm starting to think a visit to Mr. Harwood is the way forward on the electrical gremlins, but wondered if the above is likely to be a fault with the EVC ? Or a setup issue ? Or a wiring issue ? The wiring side gt-art have recently done. Cheers Matt Link to comment Share on other sites More sharing options...
Alex Posted July 19, 2006 Share Posted July 19, 2006 I'd say try another one...if someone has one you can test. It sounds like faulty wiring...but there should be a way to hard reset the unit like a hole you can stick a pin into. Link to comment Share on other sites More sharing options...
Muffleman Posted July 19, 2006 Author Share Posted July 19, 2006 Yeah, the hard reset and re-setup is what Trial were supposed to do. I'm trying to find instructions on the 'net, but it's an older unit. Link to comment Share on other sites More sharing options...

Muffleman Posted July 19, 2006 Author Share Posted July 19, 2006 I'd say try another one...if someone has one you can test. I believe the head unit won't work with the 'brain' from another unit ? Link to comment Share on other sites More sharing options...
Alex Posted July 19, 2006 Share Posted July 19, 2006 Really?? I'd rip it out and get a different EBC. Blitz or Turbosmart. Or are you saying it's hooked into the Fcon V Pro? Link to comment Share on other sites More sharing options...
Muffleman Posted July 19, 2006 Author Share Posted July 19, 2006 Gt-art have soldered it in, so don't really want to change - I guess I could. Link to comment Share on other sites More sharing options...
Alex Posted July 19, 2006 Share Posted July 19, 2006 The fact that the TPS and RPM signal is wrong just shows that it's setup wrong/installed badly. Matt H will sort you out. Link to comment Share on other sites More sharing options...

Nic Posted July 20, 2006 Share Posted July 20, 2006 It is a very old boost controller and probably has a fault (I had a IV expire after just a couple of years). How about a brand new Blitz i-color to go with the rest of your colourful car I'm organising a group buy at the moment see here: http://mkivsupra.net/vbb/showthread.php?t=75766 http://www.blitz.co.jp/products/electonic/iColor_series/SBC_IC_slide.gif Link to comment Share on other sites More sharing options...
Robbie Posted July 20, 2006 Share Posted July 20, 2006 Gary Wired in my old evc 4 and it worked fine. I'd be surprised if its done wrong but it's worth checking the unit isnt faultly first. Link to comment Share on other sites More sharing options...
Muffleman Posted July 31, 2006 Author Share Posted July 31, 2006 Well this is weird. My boost gauge was knackered as per this thread http://www.mkivsupra.net/vbb/showthread.php?t=75134&highlight=boost+gauge. Kept my eye on ebay and eventually found a second hand boost gauge exactly the same. Won the auction, fitted the boost gauge and voila ! the boost gauge is working fine. Thing is, now the boost controller seems to be working The rpms go up and down, the boost controller is reading the same as the gauge. Oh well. Met up with Mr. Harwood at JAE and had a chat, agreed to pop down there to check this out and I think I still will - peace of mind and all that. Tis strange that it's now working.

Alex Posted July 31, 2006 Share Posted July 31, 2006 Do they have the same connection/controller? If so maybe the fault in the boost gauge was throwing out the the rest of the attached units? Earthing fault etc inside the unit? Link to comment Share on other sites More sharing options...
Muffleman Posted August 1, 2006 Author Share Posted August 1, 2006 I've been trying to work out why how there maybe a link, but you could be right with the earth fault. Link to comment Share on other sites More sharing options...
