As a profesional I defintly want topology. If I was just working on my own stuff I Probably would not spend the extra money unless price was not a concern. https://yabb.autonerdz.com/cgi/yabb2//YaBB.pl?num=1707135021 The Autonerdz Community Forums/For Non-Technicians https://yabb.autonerdz.com/cgi/yabb2//YaBB.pl?num=1707135021 Tue, 6 Feb 2024 11:11:57 GMT Don't know about beemer, but Rosstec for VW/Audi use one source, but again you buy for a day and free to down load. Is usually car specific. https://yabb.autonerdz.com/cgi/yabb2//YaBB.pl?num=1627958550 The Autonerdz Community Forums/For Non-Technicians https://yabb.autonerdz.com/cgi/yabb2//YaBB.pl?num=1627958550 grantedwardbaker77@gmail.com (Grant B) Tue, 3 Aug 2021 13:33:37 GMT PICABOO,<br /><br />Member map is not mobile phone friendly.

It has never returned & the engine has run fine for about 8 years now.<br /><br />This was a very subtle problem and many of the better mechanics I know were unable to diagnose this problem. I diagnosed it by accident, but I'll take it any way I can get it! https://yabb.autonerdz.com/cgi/yabb2//YaBB.pl?num=1522765521 The Autonerdz Community Forums/For Non-Technicians https://yabb.autonerdz.com/cgi/yabb2//YaBB.pl?num=1522765521 Sat, 7 Apr 2018 00:41:48 GMT Thanks. Can't compare the accuracy of yours. I would love to get the WPS but for what I do for family and friends and doing it for free, for it's price doesn't justify it. BTW I'm from New York. https://yabb.autonerdz.com/cgi/yabb2//YaBB.pl?num=1507028528 The Autonerdz Community Forums/For Non-Technicians https://yabb.autonerdz.com/cgi/yabb2//YaBB.pl?num=1507028528 Tue, 3 Oct 2017 17:31:56 GMT IMO, KV seems a little high but burn time frame is around 1.3 to 1.5 MS,  which is good, don't see anything in the rise or fall of the burn which looks offensive. In my opinon they look pretty good and 3-4 don't look much different than 1-2.<br /><br />Would like too see some scan data over pico looking @ fuel trims (miss fire data ect) and the like as I don't see this as an ignition issue. You stated 3 and 4 has issues, what is your basis for that?<br /><br />Also do a volumetric effeciency to validate engine health and breathing issues.<br /><br />Larry<br /><br /> https://yabb.autonerdz.com/cgi/yabb2//YaBB.pl?num=1496592561 The Autonerdz Community Forums/For Non-Technicians https://yabb.autonerdz.com/cgi/yabb2//YaBB.pl?num=1496592561 step1234r@gmail.com (caseprobe) Sun, 4 Jun 2017 16:09:21 GMT Captured this vacuum waveform  from a renault 1.6  4 cylinder 16v,clearly something a miss  on I think cylinder 3 one of the cylinders that was way down on  compression then went back to normal,valve issues? https://yabb.autonerdz.com/cgi/yabb2//YaBB.pl?num=1496140077 The Autonerdz Community Forums/For Non-Technicians https://yabb.autonerdz.com/cgi/yabb2//YaBB.pl?num=1496140077 step1234r@gmail.com (caseprobe) Tue, 30 May 2017 21:16:36 GMT So not an issue,I must admit its the first time Ive seen this scoping O2 sensor outputs   <br />many thanks https://yabb.autonerdz.com/cgi/yabb2//YaBB.pl?num=1485435475 The Autonerdz Community Forums/For Non-Technicians https://yabb.autonerdz.com/cgi/yabb2//YaBB.pl?num=1485435475 rayyergeau@gmail.com (rayray) Thu, 26 Jan 2017 20:14:49 GMT All fixes I found is to replace the APP sensor<br /><br />Code p2122? p2125?, p2127?<br /><br />8 cavity APP connector, ck the blk, blk/wht, brn wires for good grounds.<br /><br />ck the grn, red/org for 5v on the reference wires from the ecm.<br /><br />Scope the wht and pink wires, both should start at ,5v and both should climb to near 5v at WOT. Do this key on engine off and running.<br /><br />Have someone else drive the vehicle and monitor the signals for glitches. Also scope the signals near the ecm, there may be a damaged harness wire.  <br /><br />Ray
