Summary of change:
Hi, My projectcar is a 205 GTI with a 1.9 litre 8 valve engine. I turbocharged it some time ago and am now fully rebuilding/upgrading the engine to suit high boost. Have a look at my project webpage http://www.205turbo.nl I;m looking into VEMS because I think it more advanced than the megasquirt i'm running now. --- specs in a nutshell: alloy 1905 CC wetliner engine 16 valve cyl head Mitsu td05 16g turbo --- update 18-08-05 ---- Ok, got the vems all wired up. Everything seems to respond ok. Put in the 023 with megatune firmware version. (And used Dave Bruls' config files with small modifications.) And also megatune seems to work fine. Will try to start the car one of these days. * Only problem is the volt meter in Megatune. It gives 20 volt readings while battery voltage is 13 v. ** You probably missed to calibrate it, adjust battery calibration. Default batt_cal=0xBC (decimal 188) or so *** thanks for that! --- update 14-09-05 Ok things are getting along quite nicely. The engine turns. I get an RPM sgignal There is fuel coming out of the injectors but still no spark. will have to look deeper into that. Running wasted spark. (bosch coil) there is +12v on the ignition drivers (00 and 01) but it seems they do nog get switched. put the folowing line in tables.txt h[2]=00 01 00 00 00 00 00 00 these are in the config.txt: ignchmax=01 filled the ignition table set the ignition settings as follows: ignition outputs: 01..00 ignition driver type: DUMMY ivert driver output Disabled chargetime @ 14v 3.46 chargetime add @ 6v 4.18 set the trigger seetings as follows: edge: rising type: multitooth Filtering: disabled TDC after the trigger (deg): 62.0 number of teeth on wheel: 58 trigger tooth: 8 next trigger tooth: 30 Cranck min.period: 1280 angular with of tooth: 6 angular with of missing tooth: 18. But I assume that to be quite ok because the RPM shows up (or is that a wrong conclusion) set crancking advance to 20.00 degrees Problem is there is no spark at all. Checked the +12v to the coil (and up to the vems) and seems ok. Anny suggestions to where to start trouble shooting would be welcome.
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
