| typical of an a-class program at least in terms of the difference. That is, comparing to the other JWT dynochart showing a 13:1 A/F mixture. That chart also doesn't show what the correction factor is and basing from the other chart at a factor of 1.22, that car was only producing 275RWHP and 276RWTQ actual. 13.5:1 is a bit on the lean side, but be sure to remember this dynochart: [ http://twinturbo.net/net/viewmsg.aspx?forum=general&msg_id=1888402 ] and see that it is making significantly more power (316RWHP and 328RWTQ actual) and running 13:1. The additional load ShakaShaun's engine is under is driving the mixture richer too. My C-class program runs richer than the JWT program, so we would have expected to see mixtures even richer than this if it were a c-class tune. I offered to ShakaShaun in this post to send a free chip for testing just to prove my point: [ http://twinturbo.net/net/viewmsg.aspx?forum=general&msg_id=1888568 ] but I haven't gotten a response back from him either on this forum or through email. Woody claims that the dyno always reads leaner in this post: [ http://twinturbo.net/net/viewmsg.aspx?forum=general&msg_id=1888642 ] I would suggest to buy a new sensor to take with you, install a bung in the downpipe, and put the sensor directly into the exhaust so that you get accurate results. The sensor simply unplugs from the DAQ cable. I'm more than happy to provide a free EPROM of my c-class program to test if someone is willing.
