It takes time to get it all right. I would lower the cranking dwell to 2 and the normal to 1.6-1.8

Finished putting the engine harness in, modified a new cylinder one coil. Adjusted my dwell settings in megasquirt and car fired right up again like it was nothing.
I am still getting the issue of it idling lean as hell and misfiring really bad under load, I fear I have a clogged fuel filter or something along those lines. I replaced everything except the gas tank when I had the sub frame out originally but I guess the inside of the tank was dirty or rusty causing shit to get into the system. I'll pull the filter off tomorrow and see what's going on. I hope I don't have to replace my gas tank. :(

Cranking 4.5ms
Nominal 3.4ms
Duration 1.0ms
I've been running it this way for over a year FWIW. I based my settings on what I saw in other people's settings for an M52 ignition coil. I haven't done an instrumented test to see if it's right but I don't have any trouble with it.

interesting. I am currently at 2, 1.6,1 with no issues to report either. We are all using OBDII coil packs too.

So I pulled my fuel pump and looked in the tank, pretty rusty and gross so I swapped the tank and fuel filter. It solved my lean idle issue I was having and the car runs a million times better now. No pics of the new tank or anything phone was dead and I didn't feel like getting the camera.
Now I'm blowing fuses for my fuel pump. Kinda weird I think my car is cursed.. I've been running the same tre 255 lph pump for a while now. I am leaning out while in boost in second gear. so I gotta figure that out now too. I just want my car to work right, it's kinda getting old driving my truck around.

sam_; Yeah good games I enjoy all of them. Although haven't had much time for video games in a while just too busy.
Originally posted by Dj Buttchug View Postdamn dont do that. so what you have to drop the tank now?
I cannot wrap my head around what it can be, I have all my engine constants set up correctly, checked timing, have a okay ignition map, one step colder spark plugs, and good compression that I checked today just because I never did do that.
Here's my ignition settings and table:
The other weird thing I noticed today was that I got my idle pretty dialed in at 14.7:1 drove the car around the neighborhood, got on it a little and when I got back to my house I was at like 18-19:1 afr. I didn't change the maps or anything and I saw I was leaning out towards the top end when driving so I backed off. Could my fuel pump itself be clogged with rust and crap from my old tank still? Is a TRE 255lph pump not enough to support my ID1000 injectors? Like what am I missing here guys???

Well after fighting for a few months now to get my car running right I think it is finally resolved!!! I changed the fuel tanks, filter, and finally just finished swapping out my ID1000 injectors for some siemen deka 60# ones since I was having a serious misfires and no power. Also redid all my base maps in megasquirt, adjusted req_fuel for the new injectors and drove the car around the block. IT FELT AMAZING, probably the best the car has felt since I owned it. Seems like it has a couple small hiccups in the timing table in the mid range but overall feels good. I'm basically at the point of resolving a few small issues then getting some solid road tuning and data logging in. :)
quick crappy cell picture outside my house as I charged my laptop/
I did all my base maps up to about 15 psi this time because I'm eventually going to start slowing increasing my boost until I can run my 1 bar HKS wastegate on the T25. I'm just hoping this stock M42 will take it. I haven't seen anyone running above like 10-11 pounds on a stock headgasket without lowering the compression so we will see what happens, maybe it'll blow up or maybe it'll be awesome..

But best idea is MLS gasket and ARP studs. Cheaper than rebuilding an engine

Only okay recent picture I have. I added some ponies with the barn built sticker.
Car has been driving pretty well, it begs to be in boost. I'm trying to work out the light throttle cruising around town just to make it a little more daily drive-able constantly needing to put your foot into it is fine but driving late at night in the neighborhood I feel bad. It isn't terrible now but I think getting some better timing down low will help out. I am also getting serious overrun backfires I think it is lean backfires since I have overrun fuel cut on. I still want another muffler because it is still loud inside the car with the resonator and muffler.
Just going to keep driving it and tweaking the tune. I gotta fix my newly found oil leaks from what looks like the oil filter housing again and my oil pressure gauge behind the head. If all goes well I should be able to drive the Friday night drift party at the end of the month.

Put my junk on the alignment rack last weekend. I have ruined this car with the e36 5-lug. My front camber is about -1 degree, front caster is like 10 degrees, and front toe is fine I forget what is was te sheet is in my glove box. The rear of this thing is also pretty f'd up I have about 1 degree of difference between each side with camber, so somethins is either bent or the chassis itself is tweeked which could be very I'm pretty sure the previous owner put the thing in a ditch at least once. But hey at least my steering wheel is straight....
I put a slightly smaller tire on in the front too so I don't hit the sway bar lock to lock. It's a 205 45 r16 on a 16x8 style 5; Honestly it is a little too stretched for my liking but I'm going to leave it for now. I also put my sorta broken bumper on the car, I didn't have the plastic bumper brackets since my car never came with them and my valance is all sorta messed up so I drilled a small hole on either side under the trim to fit 2 zip ties. It looks good enough I think.
I love having the bumper though, it makes the car look way better even with the mismatched paint and bent valance.
Drove around a little with my friend, idk why his 240 always looks good but it does. I think it has something to do with the work wheels up front. Also it isn't dumb and low like all the other 240sx's I see, it is at the perfect ride height. Also he kills it on track with his stock SR check it out.

Right after I took that poor quality bridge picture I was doing donuts and figure 8's in a parking lot and started to get hot. My stupid -8 coolant line on the cylinder head popped off and leaked coolant everywhere thankfully I caught it fast.
Struggled and got it back on then babbied the car home. During the week I fixed it by cleaning all the crappy corrsion off the barb and putting a better -6 size AN line on it. Honestly I hate making AN lines but it is pretty cheap to just buy the line and fittings compared to a premade line espically mine because it is sorta long. Fingers crossed this one doesn't pop off.
