    280zx ignition module with Megasquirt - is it necessary?

    Wow. I keep email after email notification about my thread.... Thanks for all the posts, and gollum, again, you engine bay looks wicked... And the dash, well she might never win beauty contests but! I'd much rather work on your set up than any others!!!! And it's not ugly, it just has more function than form.... However! I must call things to order for a few posts! Gollum: you say i have a bip 373 installed already??? If i'd built it, i'd know it inside and out but not only didn't i build it, I didn't even orser/buy it (previous owner). I'll have to check it out, now i want to know where the bip 373 is at, and if it's set up properly (i'll see if the msextra manual calls for modifications or jumpers to make it work)... If we're (well, i'm) in business, i'll have to figure what the other wires conected to the ignitor module do, and if i can simply delete it all... Man, you've given me hope for a potential inexpensive fix... Well if the ignitor system is broken (for all my luck, it might be fully functionnal and my problem is something else). Ill keep you guys posted..... S.

    Turbo race car, high or low compression ratio?

    when you think of compression, it helps to think of how much boost you think you`ll need to achieve your hp goal. to get 300-350, you need something like 10-15psi on a t3-t4 turbo. so you need to think of how much compression you get can away with for that psi... 8.1 is PLENTY low enough for those numbers if you manage your gas well. I think mildly dished pistons gets you that. I`m pretty certain flat pistons get you something like 9.x CR.. you might also want to think of which turbo you`re getting. if you want too spool time and low rpm boost threashold, you need a smaller torbo. that would be great, but you`d have to take into consideration that smaller turbo create a bit more heat (bigger intercooler OR lower CR ratio) and run out of breath earlier, although if you`re building an engine that won`t see anything much above 6000 rpms, you can probably get away with a lot. I`d call a turbo shop (one of the big company) and tell them what you want so you can get an idea of what turbo you need and what kind of psi you`ll need at 6000 rpm to get 350 hp (maybe ask for 4000, so you have some margin of error, and room to grow). if you run on e85, or on a mix of gas/r85, some ECUs will adjust the AFR accordingly (maybe even boost level). running e85 will get you less detonation, so you can run higher boost/get more hp with it. this way, you can get e85 for races, and still get gaz anywhere if you`re simply cruising on the street. but I'm not certain MS has that yet..

    280zx ignition module with Megasquirt - is it necessary?

    so, someone, a few months ago, asked me to post a photo of my MS2. it's been a while, but I just got one, after re-soldering a good 1/2 of my connector's wiring, some for fun (the guy who made it didn't do a clean job, I did everything I touched neat with shrink wrap and everything). here is it.
  4. yeah, man, even though it's been done to death, id'love to see how you fixed up al that rust and whatever else you've done to it. s.
  5. nice work indeed. must be awesome after pretty much making her yourself. tell me, with a t3, when does boost come on? (rpm-wise) seb

    Compare your Dyno sheets HERE

    Wow tim. I had to check things out properly because it looks like the video is manipulated and plays at about twice the normal speed when the car accelerates.. so just to confirm, this is your car? and this is a realtime video? basically, you drive a freaking rocket! that is sooo cool..
  7. Can you have it moved forward? Would it show all that much?

    Twin cam head for the L6 from Derek at Datsunworks

    that is very cool. the filter /intake stuff is interesting. is it a modified stock one?

    Gollum, that is NICE. what are you using to trigger each coil? the new wheel tells the MS2 where the engine is at, but what sends the current to each coil? s

    Twin cam head for the L6 from Derek at Datsunworks

    Ineptitude.. if this thread is what got you going, then the answer is obvious: a L28 with a set of heads from Derek..
  11. yeah, shaved/close to body chromed bumped are really beautiful. I've seen a few threads where people had done that, and it's simply gorgeous.....
  12. I forget if you're going for super stock, but pre-black bumbers, the ones with the chrome, might look good... just a though.

    Guys, guys, guys... Forget about di and mpi. Thats the past. Derek, you need to work out a head that does what the mazda skyactiveX will do: sparkless ignition like the diesels. Shouldn't take you too long to mod a few things here and there. I'll hold your beer while you do it. Although you might want to drink it to prevent headaches...

    280zx ignition module with Megasquirt - is it necessary?

    hi! softopz.. I've got a stock ZXT dizzy, with the (i believe) stock wire going all the way to the MS2, where the end was cut open and the wires spliced in to the connector, (and a resistor, somewhere if I remember correctly). The shield, on the ECU side, was simply there, but not grounded, so I ran a wire from that to the engine, to the same ground as the MS2 is grounded. in the next few weeks, I'll actually solder this and ground it to the MS2 instead of all the way back to the engine. The link I posted, I realized after, seems to be for direct coil driving, while in my case, the ECU sends a signal to the stock ignition module, which then drives the coil. Since this is how it's set up, I suspect that my MS2 is not setup for direct drive, but I'll try to see that when I solder the ground properly; while i'm at it, i'll open the board and sneak a peak at it to try to see what I can find there. I used to have a photo, but can't find it anymore.. I might take a new one and post it back here... as for the ign setting,s i'll try to grab the info at the same time and post back.. one thing you mention, about the grounds, is kindof what I've been thinking about; all the ground pins are essentially the same, just many ports to the same ground, which means that, theoretically, I could ground anything that needs grounding (like the O2 sensor, the timing signal shield, and tps sensor) in any of the ground pins? and what's a black white sensor? do you mean the ground for the ign. timing sensor? thanks for taking the time. seb
