momo Posted May 14, 2014 Report Share Posted May 14, 2014 I've just come across this video on Facebook - it's a video which fully tests "a" performance chip bought from eBay. Now I know some chips seem to work, but I found this very interesting. http://www.youtube.com/watch?v=VGtImIP6j3A&list=UUgJRL30YS6XFxq9Ga8W2J3A&feature=share&index=1 Especially the bit at the end where the electrical engineer has had a look at it. It's a long video but well worth a watch! Also - because of this i'd never buy one! Remaaaaaaaaaaaap only for me! S444M 1 Quote Link to comment Share on other sites More sharing options...
TriggerFish Posted May 14, 2014 Report Share Posted May 14, 2014 I saw this pop up on facebook, but didn't get time to watch, so thanks for posting it. I love his shirt though - healthiest! Quote Link to comment Share on other sites More sharing options...
TriggerFish Posted May 14, 2014 Report Share Posted May 14, 2014 Wow, that's pretty damning! In fairness, the phrase 'chip' is a bit ambiguous, as with older cars, like the E30, you don't map the stock ECU (or in the most part you don't), you buy another EEEPROM chip with a new map on it already. It's basically the same as a generic remap, but for the old school ECUs. These too are about the same cost and do give results. Quote Link to comment Share on other sites More sharing options...
AdDaMan Posted May 14, 2014 Report Share Posted May 14, 2014 nice vid but hardly news is it! And also you should change your title as this is NOT a tuning box. Those actually do serve a function. Quote Link to comment Share on other sites More sharing options...
bungers Posted May 14, 2014 Report Share Posted May 14, 2014 I like these chaps videos, watched one a few years back ref restoring plastic headlights I think? Quote Link to comment Share on other sites More sharing options...
TriggerFish Posted May 14, 2014 Report Share Posted May 14, 2014 They do quite a few good things. The leaf blower supercharger/electric turbos was quite good too. Tuning boxes are another can of worms. So do 'stuff', so are just resistors. Quote Link to comment Share on other sites More sharing options...
Knuckle Posted May 15, 2014 Report Share Posted May 15, 2014 My dad has had a tuning box on hie e90 320d for 5-6 years. Big improvment on power no difference on economy and it's caused no problems at all. Cost around a hundred quid. Brother just bought one too and his is great in a 120d Quote Link to comment Share on other sites More sharing options...
SpanneR Posted May 15, 2014 Report Share Posted May 15, 2014 These guys are awesome not all tuning boxes are bad but they all do the same thing, fool the ECU sensors by modifying the outputs. momo 1 Quote Link to comment Share on other sites More sharing options...
MRyan Posted May 15, 2014 Report Share Posted May 15, 2014 Good old mighty car mods, I've watched most of their videos! Quote Link to comment Share on other sites More sharing options...
rickeh Posted May 20, 2014 Report Share Posted May 20, 2014 I think tuning boxes can work in Diesels, but definitely not on a petrol. Either way, best to just get it remapped and get a custom map for your car - no car will be the exact same. Ps, MCM youtube is amazing, check out their other vids Quote Link to comment Share on other sites More sharing options...
