My manual just shows the general area where the connector is but not the sensor itself. Thankyou. Norm

Have you tried the steps for verifying your pc serial port starting on #22? http://www.megasquirt.info/v22manual/mass.htm. Also is your serial cable straight thru as specified? Good luck. Norm

What can I use to trigger the MS on my 86 3.0 v6 turbo? My manual indicates that there is a crank angle sensor but I don't know where it is. Or is it possible to trigger it from the distributer? I would really appreciate any help. Norm

It's surprising the engine would start right up if the pump isn't turning on until you actually crank it over. Seems like the fuel pressure would have bled off while it was sitting, at least mine always does. I would put a fuel pressure gauge in the line so I could see if it is actually pumping before cranking it over. That would also let you check fuel pressure under boost to make sure it is rising 1-1 with the boost to see if that is where your power is going over 3k. I suppose you could have had fuel or exhaust restrictions on your NA that wouldn't have been a problem until you installed the turbo. Norm

It's the pits when you only get a couple runs but at least you were out there. The 60' wasn't that bad and like you said if you hadn't let off you would have probably made it into the 14's. I would expect the mph to be in the 90+ range on a stockish 350 with a good transmission. Hope your tranny rebuild goes well. Norm

It doesn't matter who had the idea first. Just as long as I can steal it and take all the credit myself when I brag to my friends about how smart I am. Unfortunately I may have to put my big intercooler, Megasquirt and the Holset on my turbo 2.3 Ford for now since we are using the 280zxt for daily transportation. Eventually I'll get to the Z. Norm

Thanks for the advice guys. A member of a newly formed local zcar club http://www.roguevalleyz.com has a na 300zx that he is parting out so I can pull everthing I need to put on my car. I have removed the my intake plenum and started cleaning things up. Getting the harnesses out will be quite a challenge. It also burned a small section of the harness that runs thru the core support so that will have to be replaced. It is interesting to see which things did and didn't get burned. The fan and shroud burned but the radiator hoses didn't. In addition to flushing the crankcase I will also need to flush the coolant passages. I will also replace the timing belt. I suppose if I should decide to sell this car some time it would be best to stick with stock electronics. Norm

I've been waiting to see how your combo works out. It looks like you have a great combo that should make awesome power. I especially like your choice of turbos since I too have been running an HY-35 on my 2.3 Mustang. Plus that NPR ought to flow very well. Congrats on getting it running and please keep us posted! PS. I just assembled my MS and will eventually follow in your footsteps. Norm

I am no expert, I recently assembled my 1st MS 2.2 board but I have several years in electronics. First thing I would verify that the com port is communicating with the MS. If you go to the assembly instructions http://www.megasquirt.info/v22manual/mass.htm#guide you will find instructions for jumpering pin 2 and 3 on the db9 serial connector that connects to the MS and testing the connection with Hyperterminal. If that works I would verify that I had 12 volts to pin 26 on the MS db 37 connector when the ignition switch is on. Of course I would check the ground connections to the MS and relays. BTW I think you want power to the pin 86 on both relays both in the start and run position but not in the accessory position. Good luck. Norm

Another question about the 300zxt. Is the transmission and cruise controlled by the factory ecu? Thankyou. Norm

I don't think the fire was hot enough to damage the engine itself since the paint wasn't burned on the valve covers etc. Mostly plastic and rubber. I planned to follow the sticky for the L28 engine for the MS install but I don't know if there are things I would need to do specifically for the 300zx. Once again I want to thank you for your insight since I couldn't find much info on a 300zx MS install doing a search. Norm

I bought an 86 300zxt that had an engine fire. Some of the engine harness is ruined as well as some hoses etc. My first thought was to replace all the parts from a donor car to get the car running. Now I am wondering if it would be wiser to get a MSnSpark or to get the car running first with stock electronics. I'm not sure how much of the factory harness would be used anyway. I have an electronics background but have never installed a standalone ignition system. Car supposedly ran fine before the fire (leaky injectors) and has 91k miles, hasn't been started since 1992. I appreciate any suggestions. Norm

As you know, the actuator spring pulls the rod in so you use a stiff coil spring to help pull it out so it doesn't require as much boost to push the actuator open. Mine had an adjustable rod so I unscrewed the coupler and tapped longer threads onto the diaphram end of the rod to screw on an adjusting nut. The spring then goes onto the shaft against the diaphram housing, then a washer and adjusting nut. I found by using a really stiff spring I could run the boost at 15 psi or less until I was able to ad more fuel. Since then I have been able to run 25+ psi with without detonation partially due to water/alky. Everyone that has used one on the 2.3 Ford has found that 15 psi with the Holset has as much power as the stock t3 at 20+ psi. I was told it was due to the cooler/densor air charge due to improved efficiency. Surprisingly I noticed only 1 or 2 hundred difference in spoolup rpm. Norm.

Hope you don't mind a Newbie here chiming in. I as well as several Turbo Ford people are running Holsets including Hy-35 and Hx-35s. I was able to use the stock Hy-35 actuator by putting a stiff spring with an adjusting nut on the actuator shaft to lower the internal spring rate. As far as a compressor map I found this link for an Hx-35 posted on Turboford.org. and is nearly the same for the Hy-35, the main difference being the exhaust/turbine housing.
