Dadaluma Posted December 29, 2011 Share Posted December 29, 2011 i am really confused as how to set the base timing on my car, 240z/vg30et ms2 using tunerstudio stock nissan CAS. my problem is when i check the timing with a light while cranking, while the dizzy is in its normal posistion its at least 40+ degrees too advanced. I have tried changing the trigger angle from 0 to 60 and tried adjusting the spark advance table, no change from either. i have read that your supposed to set a fixed angle so as not use the igntion table but i cannot even find that option in tunerstudio. I am really confused as what steps to take from here.If someone could give me an idea about what i might be doing wrong here, or maybe give me a step by step guide to setting base timing that would really help.

Matt Cramer Posted December 29, 2011 Share Posted December 29, 2011 What firmware are you using? Some options don't appear in all firmware versions, and fixed angle is one of them. Quote Link to comment Share on other sites More sharing options...
Dadaluma Posted December 30, 2011 Author Share Posted December 30, 2011 I am using v2.90 embedded code,serial signature 2.9050, tunerstudio ms v1.044. I am using this on a m2s kit v3.0 pcb. -thanks matt Quote Link to comment Share on other sites More sharing options...
letitsnow Posted December 30, 2011 Share Posted December 30, 2011 If you can't find the fixed angle option for whatever reason, export your spark map, set the whole thing to 10, set timing, import the spark map. Set the timing by changing the trigger angle, messing with the adders, and the position of the dizzy until the timing light matches the spark map.

letitsnow Posted December 30, 2011 Share Posted December 30, 2011 You should look over your settings, how are you driving your coil? Quote Link to comment Share on other sites More sharing options...
Dadaluma Posted December 30, 2011 Author Share Posted December 30, 2011 i am driving the coil with the ms2's ignition driver, utilizing the stock nissan CAS igntion settings are: rising edge/trigger rise/standard coil charge/going high(inverted) with 10 deg spark map and a 60 deg trigger offset Quote Link to comment Share on other sites More sharing options...
Dadaluma Posted December 30, 2011 Author Share Posted December 30, 2011 I just reflashed my ms2 with newer vesion: ms2/exta alpha 3.2.0, what do i put under "spark mode" would basic trigger be right, my other version did not have this thanks Quote Link to comment Share on other sites More sharing options...
BLOZ UP Posted December 30, 2011 Share Posted December 30, 2011 (edited) Yes, basic trigger. Do you have a build thread somewhere? Edited December 30, 2011 by BLOZ UP Quote Link to comment Share on other sites More sharing options...
Dadaluma Posted December 31, 2011 Author Share Posted December 31, 2011 No I do not, do you mean what setup I am using?,I am new to this forum thing. I believe that I am one of the few vg swapped s30's. Here is whats on my car 71 240z: vg30et 7.8:1 t5 trans Holset h1c mercedes 420cc inj. tial 38mm WG generic intercooler 3 inch exhaust ms2 ecu gutted intake plenum Any other info I would be glad to give thanks for all the help so far guys. I will try setting the timing again after work. Here is what I am going to do:set dizzy to srock location set fixed angle to 10 deg. and adjust trigger angle and dizzy until i get 10 deg. on crank timing and then set to use tabl,e sound right?

BLOZ UP Posted December 31, 2011 Share Posted December 31, 2011 (edited) Attached are my settings for spark. I also have a VG30ET in my 280Z. I set the trigger angle to 60, and adjusted the distributor to match using a timing light. It's idling well at the moment, untuned anywhere else though. Stock timing is 10 degrees at idle. Cranking is set to 300rpm. I am using an aftermarket coil, MSD Blaster 2, and those coil specs are from MSD. I am using MS2-Extra 3.1, using the BIP373 ignitor, but I built the board a while ago and I trigger through JS10 (which is deprecated). I was wondering if you had any pictures of how you did your swap, etc. You should start one here.

FricFrac Posted December 31, 2011 Share Posted December 31, 2011 Lots of VG swaps here into S30s. Also check on the MS forum and search VG30ET.... Quote Link to comment Share on other sites More sharing options...
Dadaluma Posted December 31, 2011 Author Share Posted December 31, 2011 thanks for all the info, unfortuneately I dont have any build pics but i could take some of my current setup, the biggest part being turbo relocation pipe, and as far as lots of vg swapped s30's i really dont think there are that many compared to l28et or sbc, but there seem to be a lot more than i thought. thanks again -James Quote Link to comment Share on other sites More sharing options...
Dadaluma Posted December 31, 2011 Author Share Posted December 31, 2011 got it showing 10 degrees advanced! using a 60 trig angle, now i just need to find out what keeps making tunerstudio freeze thanks a lot guys Quote Link to comment Share on other sites More sharing options...
