Also keep in mind that if you use an external transistor it will cause an inversion of the SPARK signal, so pay attention to whether or not you need to select "invert spark output" in MSnS.

I may be missing your question, are you asking about the transistor that fires the coil? If you have a version2.2 board use the transistor on the car to fire the coil, or a GM HEI module (transistor). I just hooked up my Talon 4G63 and I used the stock Talon tranistor to fire the coil (actually two transistors and 2 coils, distributorless). If you have a version 3 board you can fire the coil directly from megasquirt and not use the transistor on the car, because version 3 has the built in VB921 transistor.

What version of MSnS_Extra code are you running so you know if someone elses code will be able to load into your system?

I finished ordering my parts for EDIS8 on the 454 BBC. I got an EDIS8 module and two of the Ford 4 post coils. I already have the trigger wheel. Hopefully it will be plug and play with the info that you guys have tested and found.

I got the TC7117 from jameco, around $3. I also ordered the supporting parts from them. Download the data sheet and build according to the typical application on page 3, but make sure to substitute the correct values for 2 volt full scale operation. I turned on the decimal point to allow it to read AFR correctly and set AFRs from LC-1 to be 1v = 10AFR and 2v = 20AFR It uses 7 segment LEDs and they wire directly to the A/D with no other components. The circuit will then readout 10.00 for 1 volt and maxes out at 19.99 for 1.999 volts. It has a potentiometer to calibrate, I calibrated by using my multi-meter to read the input voltage. It requires quite a bit of wiring on the breadboard and will be fairly busy on a perf board. I am going to look at proto-typing boards that may have most of the 7 segment buses already there. Cost of all parts to build the circuit was less than $10 for me. The issue right now is that it requires -5volts so I need another regulator for the standalone gauge My breadboarding setup has -5v so it works in there. Just something fun to play around with. Figure 5.1 in the datasheet shows how to build the -5volt regulator circuit

I get questions all the time, by PM, phone, work email, instant messenger and 90% of the time the answer was in the sticky. I think its the "I don't need the manual" thing. But if you ask I will point out where it is in the sticky, becasue sometimes its hard to find one piece. The sticky is very old and really needs to be updated with MSnS_Extra information and v3.0 board specifics. I haven't built a v3.0 board yet, I keep using v2.2.

It can be done, the instructions from Tony D. are copied into the sticky guide, but it is easier to use the 83 type dizzy, even if you have to swap to the 83 it is still easier. But either one can be made to work.

Source MSnS with the 4 slot trigger, the green black wire from the 280zxt dizzy is from the 6 slot wheel, not the umpteen slot wheel . So you want to use the wire from the 4 slot wheel output on the KA24 dizzy. It was easy to tell if you got the wrong one because your cranking rpm in megatune will be crazy high if you have the 1 degree output.

BTW, the circuit is built and works as advertised. As soon as my car is running again I will test it connected to the LC-1. Then I can build an enclosure like pictured above (LD02 style).

I want a display that looks nice in the dash like the LD02 I don't want a cheap multimeter setting on the dash, fine for testing purposes, but not my choice for long term in dash gauge. I am not knocking that solution, that is great to get started and set up the car, I am just looking for a "cheap" nice looking solution.

If the dizzy has an optical wheel in it like the 280zxt and one of the decoder rings has 4 holes then it will definitely work, don't worry if no one else admits to using it. Just pop it open and verify the decoder wheel. Or post pictures of the inside. That will give you the trigger for megasquirt and work OK with spark output since it was already made for ECU control (locked advance).

I forgot to mention, but you have to reprogram your innovate unit to match the setting you use in megatune either 1-2v or 0-5v

If you have configured your ini file to use 1-2v for 10-20AFR you may want to change to 0-5v for 10-20AFR. I have seen that recomended several times on msefi.com. Just gives better resolution for the analog to digital conversion. I have seen complaints over there that the megatune AFR gauge reads different than the innovate gauge.

This may not answer your question completely, but megasquirt with MSnS_extra code controls fuel and spark. Any engine benefits from better control of fuel and spark. The engine can be tuned to perform the same regardless of which system you swap to ie- megasquirt, SDS, haltech, Z31 ecu, etc The selection of the system will come down to other arguments: price, support, reliability (doesn't seem to be an issue with any system nowadays), features, installation. Price and features were my main concerns, but yours may vary. MSnS_Extra code is the best bang for the buck when you look at the features available(if you need the features). MSnS_Extra has many features that only benefit turbo installs. Probably the single biggest thing to be aware of with megasquirt is that it is a speed density system so there is no mass air flow meter. This can be a problem if you run a very large camshaft because megasquirt works from manifold pressure which varies wildly with a big camshaft at lower rpms. The next thing is that megasquirt only supports batch firing of the injectors, so research that and make sure it is not a hangup for you. BTW, the megasquirt may exist because it is tough to install and there are a lot of questions to answer, or because it is pretty good??????

So who do I support and buy from then that you consider a little guy? I still think you should start your own oil company, I'll support you.

No, its not. To make it that simple you have to boycott all oil companies and not use any oil whatsoever, then it becomes that simple. Then you could negotiate your price. Otherwise you are a pimple on an alephants *** and all you do is cause them to change their business plan a little.

no problem, I am always amazed when I look at the manual, it is continually updated, those guys do a good job with documentation.

Megasquirt manual has all the part number info

The brakes are nice. I put about 40 rounds through my remington 300 ultra mag and then had a high quality brake put on it. First time out I put 3 rounds at 100 yards touching each other, no more anticipation. It was no pleasure to shoot without a brake. BTW, the 300 RUM is a nice round, but I still like my old hand me down 308 Model 788 remington.

some update info, it is apparently still in the works: http://www.thesporezone.co.uk/

The big question I guess, do you have an exhaust manifold to bolt the turbo up? Also what are you doing for the oil drain back from the turbo into the oil pan? Is your turbo water cooled also, or just oil cooled? Looks like you are just down to plumbing up the turbo and the intercooler. What kind of intercooler do you have?

Not surprising, a couple years back what got me started on the turbo swap was a call to datsun only junk yard that I had frequented for a year and the guy said he was going out of business, luckily I called when I did because it only gave me a week to pick throught the parts, then everything went to scrap. He had around 20-30 z cars and several engines, trannies, etc. It was sad, but I didn't have the money to stock up. He claimed the job was too stressful and I think he actually enjoyed junking the cars just to get back at the customers he didn't like???

I think of that paradox episode where the people plug the jack into their head to enter the VR game and nobody wants to come back out and be in the real world. Maybe it will consume enough people that the traffic on the interstate will lighten up.

The crank angle sensor is inside the dizzy on an 82 or 83 turbo dizzy, so if you pick one of those up you will not need any external crank angle sensor. I am not familiar with the NA 280zx dizzy. It might be easy to use it with megasquirt.

My first inclination would be that something happened during the alarm system install that caused the megasquirt memory to become corrupted. The easiest thing to try is to reflash your code and settings back on the unit. I have heard of many instances like this, but I have never had to re-flash my code.
