200sx with a Ka24de(t)

Was that Skyline running 1.1.44 then?

Ok, so I've checked the cams now. They where fine in relation to each other but they where off by maybe 15degrees to the crank
I can't believe I missed that the last time i checked it, I wonder if I was stupid enough to only look at the cams that time.
However I have now redone it the right way and should be able to test it soon.
Hope it runs a lot better now, atleast I have one less problem

No 1.1.18.
The BMW´s where all running 1.1.44 and 60-2

[Niclas_AB]

Oh, ok. Seems like there's no one running the nissan 24+1 trigger with firmware 1.1.44 then .
I think I'm forced to go with the 1.1.18 and get it up running before I'll try any newer firmware. I have enough trouble sources anyway.
Thanks for the info.

My 200sx (ca18det) is running 1.1.44 with 24+1 trigger and BOSCH wastespark coil.

Oh, nice Assa could i maybe get an .msq file from you so I can compare our settings?

Now with the cams in the right position the compression tester showed 160psi compared to 110 before, so that was good news Factory manual says that it should be between 151-175psi. But I also have 9:1 instead of original 9.5:1 comp so I think 160 is great.

Got it to idle somewhat good today, alot less missfire than before but I still have a little more missfire than normal and still having problems with the spark angle not being very consistant. The engine rev went up and down between 900-1100rpm and when you look with the timing gun the spark angle increased/decreased as the rew went up and down. I will get the loggfile up in a little while.

Found an interesting thread!

Maybe this is part of my problem as im running triggertooth 6?
Will change it to 2 or 3 and test it tomorrow :-)

Try the original 1.1.18 trigger settings.

And fix your h[1] table.
I don´t understand the whole h[1] well enough to tell you exactly what it should be like.
But it´s possible that your figures are indeed wrong and you may be igniting well wrong.

Yeeeeees! The car is now idling very nice!
Changed "Trigger tooth" to 2 and set the "Angular width of tooth" to 30 instead of 6 and it idles so smooth now.
I'm a very happy fellow now!
Thanks everyone!

Awesome ,
get it tuned and get back with some logs of the HX55 spooling

[Niclas_AB]

Well, maybe next week or the week after that.
First I have to put back a few things like the seats, front and hood 
Then my plan was to first get it going without boost to get to know everything.
But I will make sure to update this thread with my results.

This is going to be a monster, if you get boost, before redline 

What kind of boost are you planning on running?
