w00t! I bought an SDS today...

[Looneybomber]

You're selling the GReddy I/C and going with a smaller one?

I traded it for the transmission that is in there right now. (KA-E, I had the CA transmission completely rebuilt.)

Update:Ok, so I should have the ECU back from Racetech on friday. They said that it seemed perfectly fine. They said that it was pretty common for them to get wet and not work and then when the dry out, work again. So it seems that I got a pretty good deal then. After getting the update and buying some sensors and getting a couple of extra options added when they had the computer the grand total STILL came up to less than 1K. Still not bad in my book.

I'm still quite confused on the Hall sensor bracket, but may have an alternative. BioSehnSutch is currently developing a Hall sensor converter for the SDS system. Basically what it would do is use the stock CAS, convert the signal and output it to SDS ECU. That means no bracket to make, no removing the crank, no drilling, and no magnets! If we can get this to work, I'm going to see if SDS would be willing to list a "Nissan" kit that would lack the Hall sensor and magnets. This should work on basically any newer (Mid-80's and up) Nissan. The current program is for 4cyl, but it should only require some minor re-programming for the V6's. If we can get it to work it will MAJORLY simplify the installation of the SDS unit on a Nissan.

i am thinking of ditching the NISSAN CAS in favour for teh hallsensor.. i have 4 sensors and all have their quirks... i thought that once set up right those hall sensor and similar trigger wheels ar better and more accurate...

You are flirting with disaster. Stop being lazy and make the hall sensor or pay someone to do it . The only system they have that will work with nissan systems is the D system which is designed for cars with distributors. Haltec and microtech standalones can be triggered by nissan/mitsubishi/hitachi's crank angle sensors. SDS cannot as it is triggered by true earth magnets. Ryan, take my advice and just get a bracket made. It ain't cheap, but it's worth every $ you spend.

Meh. When my new programmer shows up I'm going to build a test system. It'll either work or it won't, the circuit design is plenty fast for 20,000+ RPM operation, assuming the inputs are clean enough (unlikely).

The program is simple and has been tested (simulator) but onceI can program the real thing I'm going to make a prototype and test it manually, then ship it to him to guineapig.

I'm all about the overkill engineering. Worst case scenario it ****s up and he's stranded.

The Hall sensor connection to the SDS is just an on/off of a 5V return from the SDS to itself, so I just have to switch that with a large enough degree window. if it misses at high RPM I just reprogram for a higher degree output window, right now its set for +-3 degrees.

In theory this could be used on basically all 4cyl nissans, and with some slight modification to the code on 6 cyl's as well (at least VGs, and probably RBs, don't have FSMs for them to check the signalling).

I've already spoken to Barry at Racetech about it and he was more than helpful in providing me with as much information as he could and seemed very intrested in knowing whether we were successful or not. The worst case scenario on my part would be that one of the coils misses the off signal and doesn't shut off as it should. I could theoretically burn up the coil circutry, but as long as I properly fuse the coil packs (7.5A) as I'm supposed to do anyway, I certainly won't hurt anything. As Sehn said the SDS ECU is simply looking for a return on a 5V output that it's sending to the Hall sensors. As far as the ECU is concerned, it doesn't care what is on the other end making it get the voltage back, as long as it gets that signal.

Maybe if Dee could hook me up with some pictures of how this bracket looks it would help. I don't see how you can get that bracket infront of the alternator on a RWD CA18DET and still have it set behind the Crank Pully...

w00t! I just got it back. It's like 9am on Friday. They mailed it back to me the day after they got it. They have to have THE BEST customer service I've ever encountered. I mean, I didn't even really buy the product from them. Anyway, I'm impressed.

As for the car and installing it, I plan on getting started next week. I'm contemplating hooking the car up normally and getting it all tuned and everything and THEN trying out the thing that Sehn is working on for me. We'll see how modivated I get. Plus it'll take me a couple of weeks to get the few hundred it's gonna cost me a to have the bracket made and the magnets mounted. Oh well, gotta pay to play, right?

That bracket is pretty simple, but a prototype would help even more for degrees of angle and final sensor positioning. Remind me during the weekend to get you some pics of my hall sensor bracket. Mine is currently off the engine because the engine is sitting at a machine shop waiting for yet a 3rd crank since the last one I had was bent and had a warped nose where the flywheel sits.

Thanks Dee, I'll shoot you an email.
