mspnp2 and nb2 engine swap help
 
i just recently put a 01 vvt engine in my 92. i wired everything based off of savington's post and greg's from thecarpassionchannel.
i installed mspnp2 and the car wont start, injectors arent firing based off the fact that my spark plugs dont have any fuel on them, and have no spark from either of my 01 coils.... wired based off savington post.
ive checked and double checked all the wiring, so im fairly certain the problem is with ms, but im new to megasquirt.

ive selected 99-00 trigger wheel under ign. settings, which i believe is the same as 01-05 trigger wheels? maybe this is the issue?
i have the cam and crank inputs wired into the stock na harness based off savingtons post, is this the issue? maybe i should wire them to ms differently, or change something inside ms?

please help!! i have too much time and money into this swap to give up!!!
thanks for any help

The 99 trigger wheel has 4 points. I'm unsure what the 01-05 one has.
I used a 36-2 wheel for my install.
To my understanding the CAS signal from the 1.6 has 4 wires. GRD , 12 v, and 2 signal wires. 1 signal wire goes to the crank angle sensor & the other goes to Cam angle sensor. both sensors have a signal ,power & ground wire. Don't recall which color wire goes where.
If your trigger wheel has a different number of teeth to the 99 one....you have a custom option.

If you have no spark. have you checked your coil?

Did you also load a 1.6 map? To suit your MS2 PnP? if not start with that & change the appropriiate settings.

I had no spark I changed everything. COP's , Trigger wheel, Cam angle sensors , crank angle sensor. and no spark. I started back with basics and the 1.6 map did the trick. perhaps I had a wrong setting somewhere. My problem was also intermittent.

Thanks for the reply! I actually have it running now, the problem was that the jumpers inside the megasquirt weren't on the right pins... I hired a guy to come to me and help figure some things out but he didn't do much. if he did anything, it was to make me figure it out myself.... dyno day coming up in a couple weeks and i cant be more excited. the car is much quicker even just on the base map with a few tweaks..
