unfortunatly i did not purchase it from you I wish I had of. I purchased it off ebay not knowing too much about ms at the time from the looks of it, It was assembled and never used the person I had bought it from got it from SparkandFuel.com. I was still hoping to either get it tested by you.

ya i checked that too its good Matt can I send my ms2 to get tested and you can ensure all the jumpers are on right. Since it was on VR and I tried to start the car which it did run than I found out I had the jumpers wrong. For EDIS is it jumpered for HALL OPTICAL ?

The old ecu system did run but it was really bad in the donor car. However I ended up swapping it over anyway and it ran it would be really rich and foul the plugs. I then rebuilt the motor and it ran well for a couple of days than reverted back to crap. Like fall on its face and pop sometimes. I cant go back im too deep besides i sold all the old zxt parts thats why i went with ms2. the engine was recently rebuild before doing the ms2 so it ran bad before the engine was rebuilt and after with the same ecu and ms2. I swapped so many parts and interchanged just to see if it was anything I had. From 2 distributors, injectors, AFM(with the old setup) fuel rail, FPR and so much more Im close to giving up. really close My timing is right and the oil pump gear and all that is installed correctly. I also checked my compression its about 140 across the board its a bit high for a turbo motor but it could be the gauge difference. I also tried to change timing from at least -10 to + 20 . Well its winter now the garage is freezing cold I probally wont touch the car too much unless I switch over to EDIS. I have all the parts needed im waiting for Derek to finish the rest of his custom parts. If it does run properly than I know it was something with distributor, wheel or shaft. If not IM BURNING THIS CAR its been 4 years of hell YES 4 YEARS I got sidetracked with diff swap and all the other jazz when I should of put all my efforts on the engine and ecu. I replaced soo many things and it still not running !. I completely re did/upgraded the whole car the bushings, struts , springs, mastercylinder, big calipers, rear discs, r200 conversion,cvs, 5sp, rebuilt motor, ms2 and the complete interior I am close to giving up.

How do I check rotor phasing? The wires look good they havent been used much and the other set I have is new.

I dont think hes running vista unless he changed the Theme looks like XP. He wont have to elevate yourself into an administor with XP.

I learned so much from this thread I had never known with spark plugs,,, I think Ill keep my 6 or switch to 7s. The reason I originally asked is Im having big issues with my car it doesnt want to seem to run new ms2 install and everyone I talked it to says with what your giving me it should RUN!

Im gettin a consistent nice spark from coil sometimes i check it to see if i got spark at that point. Then at plugs i did timing test on #1 it shows 18 degrees btdc -+ 2 degrees. I have tested 2 sets of wires and distributors and sometimes I do get spark and sometimes its intermitant. Matt I posted a video of when the car did run and the ignition option that was jumpered was VR type and it ran! I then jumpered to the proper tach and all that for Hall/Optical type and it doesnt even catch. So I was wondering if I had comprised something on the board that takes control of timing or ignition capture. I was also asking if anything was comprised would it tell me in megatune or some type of error code. Or if the only way to test it is through a stim ?

Can anyone come to my rescue ?!

Have 2 different set of plug wires and distributors. There is usually spark shows with a timing light thats how when I checked my timing. Then later set in Megatune for my trigger.Also at coil it seems to spark in a well timed pattern. Matt just the person that would know this answer! I just remembered when I got ms2 pre assembled it was set up for VR type and whats funny is the car did run and I didnt know about the type of ignition the PCB was jumpered for!? mind you it was really rich, didnt have an idle and had to open the throttle a bit. However after trying to trouble shoot reading the manual and write up I re jumpered the board for a Hall/Optical which is what type of distributor I got. I believe I changed the tach out put option and xg1 to xg2 and something else lol Basically jumpered per manual. Which leads to me where I am . Could I have damaged the board or ignition ouput? Would the stimulator test every component in pcb? I think I may need to check one more thing and thats the PCB. In megatune however everything checks out. I dont know what I got myself into :S http://www.youtube.com/watch?v=PewmUqUoFEI I took this video not too long ago the wierd thing its setup for vR type ignition now its correct and nothing. Its really whining I think its a belt or water pump bearing.

In my first reply to you I said to use the newer loader. It looks like you dont have proper connection are you still using the batterey charger . I did that and it gave me a really hard time! are you running a USB adaptor ? check if all the drivers are installed correctly. Also in the megamanual there is huge documentation on how to troubleshoot the connectivity, from using a null vs straight wire etc follow the troubleshooting guide. I believe thats some good advice now someone please help me troubleshoot my car

The plugs were not wet when I started at 2.5 around 5-6 they started getting wet. Could it possibly be spark issue? Whats wierd is I get a real hot spark at the coil. But the plugs w/ the light its intermintent Maybe Its cause I have to giggle the timing light sensor so I dunno! its driving me insane!

Remove the batterey charger in the meantime just for re flashing purposes you dont need a full 13 v disconnect fuel pump relay so power isnt waisted.

Hey I agree with you the installation guide is great info however I also had trouble understanding that part. I have ms2 which is different and the middle light on board does not light up sometimes with ms2. In the writeup says you need to move distributor while your on tdc compression stroke till your middle led lights up on the board. And that should get you really close. For ms2 this should work as well . With the gun hooked up on #1 cylinder pointing to crank pulley, increase/decrease the trigger offset till you get your desired timing. Basically you want it to flash on 17 btdc stock settings for l28et.

Im not familiar with this boot loader from what I see in the image it is 1.1 loader. Try the ms download 2.0 its more user friendly , go into settings set the proper com port. I dont remember if you can test for response from ms. -Also if your using a usb adaptor set the buffer high in ms download than in hardware /device manager/device properties right click adaptor and also set the buffer to the same Can I ask what your using to power the ms2 board? IF you are powering through batterey charger you will get wacky issues. Either use a car batterey or a 9v batterey. Hope that helps if that doesnt do the trick the megamanual has a huge page of steps dedicated to getting proper communication from ms good luck.

Okay, a little update I switched from 2 point prime to table. Started with 2.5 to 7 with increments of .5 still nothing. I will try getting new plugs in the meantime anyone got any tips ?

From reading the manual it says to put 80% of your req fuel for cranking pulsewidth so thats where I derived the 9 and 3. Matt Thanks for the reply I attached a rar with my msq inside. I will get a fresh batterey and try again. So under general setting-prime WUE/ASU Baro tables I changed from two point to table and now under other tables in megatune I can see the tables which you speak of. Ill try that and I hope thats it. However I have a feeling there is more behind this. megasquirt2008.rar

Hi before I go into my issue I would like to thank everyone in this forum I think its got allot of tremendous knowledge. I would also like to state I have searched before posting this topic. ( I also want to say I just wrote a much better post before this, but lost it to a stupid crash) I have a l28et motor that I dropped into a s30 and has been a headache since day one. I love the car but its a one way street in this relationship. I truly believe its cursed or something. I recently got ms2 pre assembled and wired it all up with new fuses/relays/sensors. Made the jumpers on the board for Hall/Optical pick up. Using high current driver also wired the distributor according to DIYautotune write up. Loaded the firmware on the board then made an msq mostly pertaining from knowledge on this site. All the gauges work except the o2 is red, however I don't believe this could be a culprit. I got a timing light and verified my timing and it flashes right at 17 btdc next to the pulley mark. My battery was strong at 13.5 volts and now does not take a charge. I am getting a tach signal, spark at coil/wires/plugs and my injectors are firing. The car doesn't seem to want to catch and idle. Not even a bit! This is what I have done so far. -check firing order 153624 counter clockwise -checked cam lobes pointing outwards on compression stroke, also checked rotor at TDC is pointing to one. - put a gauge before injectors and I get 28 psi I believe in switched power - tested the distributor off the car with a drill get signal in megatune also while cranking its 250 rpm or close to - plugs are wet I re dry between attempts - my msq is good was derived from a stock turbo zx using same everything. - calibrated tps, then checked - moved trigger offset retard and advance. - I have no egr aac none of those stuff and all vacuum hoses are tight and no leaks - lowered and raised the pulsewidth at -40 its 9 and at 160 its 3 ( although I cant seem to change the priming pulse its greyed out in the warmup wizard ) - went back to manual and says to remove r57 resistor because it interferes with timing while using the high current driver, however still nothing I'm really out of ideas. I was hoping some of you guys could help me pin point the problem and get the car running.

Thanks Naviathan, I never knew that about. The reason im asking is I have been around these cars for quite some time, and I never seen the 7 or 8 series at the auto store. They first came to my attention in sticky concerning noise supression and the common resets. However in that thread they only say 8 or 7 series I could not find the actual part #. Ill have to guess that 6 , 7 or 8 is the length in mm of the tip?

i read this somewhere about the 7 and 8 series ngks are non resistant to noise? does this sound right i got a set of ngk BPR6EGP the engine is l28et i looked at the auto store under 280zx turbo and thats what they had recommended what do you guys think are a good set with ms2 how about wires i got a set of ngk blue 8mm

im definatly in i msg u a couple of days
