Many thanks for your candid response Steve.

Could someone tell me please how to mount my 36-1 trigger wheel? How many degrees or tooth before TDC and wich parameters to insert in Tuner Studio?

the general standard is x number of teeth or degrees ahead of the sensor when at TDC

so for a 6 cylinder motor - 6 teeth ahead of the sensor

these two pages might help

I am installing frankencis with ms in my 964 turbo

Were did you guys mount the ms unit, photos?
Were did you mount the beetle temp sensor?

My plan is to fabricate spacers to move the engine wiring console away from the body, about the width the of the Microsquirt. Then I'll mount the unit behind for a stealth install.

There are no beetles in my car, only mice. Very, very scared mice.

I fabricated a bracket that mounts on the RHS side of the intake manifold using a boss that originally held some emissions tomfoolery. The bracket holds a plate with a 6 position ATC fuse block and MAP sensor on one side and the MS on the other. This allows me to power the MS and all related devices (injectors, WBo2 controller and sensor, MS...) with separate ATC style fuses. I power the fuse block from the unused of the 3 position fuse block at the rear LHS of the engine compartment. This is actually fed via a relay switched by CDI power from the delayed relay for reasons I've described in previous posts.

When I get time I'm dropping the engine for cams, clutch, and possibly some other goodies (P's and C's?). When I do that I'm installing crank and cam position sensors and using the MS to control ignition as well, and removing the dizzy and CDI box. When I do that I will likely relocate everything to where the CDI is now.

What Engine temp are you using?
And were is it located?

I drilled and tapped where the oil temp based thermo valve screws into the crankcase breather cover and use a closed element sensor there. I also have an open element IAT sensor in the neck of the intercooler just about the throttle body.

neither of these are used in any calculations for anything including WUE or ASE. I still have the stock WUR in place for that.

However, when I drop the engine I'll install the TK CHT kit for future use.

FYI -- you do not have to remove the engine to install our CHT kit, it can be done in the car without too much difficulty. Remove
* scavenge pump
* air injection pulley housing
* engine sheetmetal at cylinder #3
Cut a slot on the sheetmetal for the sensor plate, install the plate in the cooling fins, reassemble.

Thanks Chris, but I don't have any pressing need for it, and I have a long list of things to do when the motor is out (which I will call you about first lol).

Speaking of CHT, what is a safe range for CHT on these things? Or whats the yellow and red zone? On the plane I try and stay below 400*f (Lycoming says 500*f is ok) but occasionally see up to 420 for a few mins. Knowing the CHT is fine, but if you don't know whats ok and what isn't, does it really help much?

Give me some inspiration pics of your installations of the MS box and more 😃

Steve et al

I'm building a testing device to run the lambda valve and eWUR injector at user selectable duty cycles to measure the fuel delivery at various points.

What is a reasonable frequency to use as a base for the PWM control of the lambda valve? Regular fuel injector?

I was going to use 50Hz, 20ms period for both.

50Hz should be fine,

FrankenCIS operates the Frequency Valve at 100Hz, I believe the original Bosch system also ran at approximately the same frequency.

You will have around 1ms of injector dead time to contend with so if your proposed test system can handle it, increasing the frequency to 100Hz still gives you around 9ms of control range per cycle. More little pulses per second will give a smoother pressure at the fuel head.

My problem is getting below 10ms period because I can only count in milliseconds and my code loop approaches a milli to run, more when I'm operating the buttons to adjust the duty cycle. I'm taking a very simplistic approach, min duty cycle of zero, max of 90, adjust in 5% increments on each one independently. I don't think I can get anything useful below a 20ms period. I'm already seeing slight instabilities on the oscilloscope.

I think what I have is probably not the way you'd really run an injector in real life, but s/b good enough for rough numbers.

50HZ should be fine for a representation of duty cycle to fuel head flow, the curve might be off a bit compared to 100HZ, but min and max will match.

If all you are interested in is the fuel head flow range, another option for flow testing would be a little brass needle valve instead of the frequency valve
as long as it flows more than the injector you could work out the max point and then do your stepped graduations back down to fully closed

Wow thats alot of reading, alot of which I do not understand whatsoever. So with some of the tuning trouble shooting I think this set up maybe way over my head.

It's pretty simple. Buy a Microsquirt and DKUbus harness and WB O2. Buy the adjustable WUR if pre lambda, don't if not. Wire it all up. Tune. Drive.

Everything else (spark control, e-CIS) is optional.

OK Kenikh, that doens't sound as bad. I already have the WB02 sensor and Adjustable WUR.

I'd like to replace my 20 yr old Electromotive TEC1 ignition that is on my car. Would I Microsquirt take care of that? Could I keep my existing TEC1 coils?

Funny enough, I'm replacing a Tec3 with mine and plan on using the Electromotive coils as well. They can be used with an inline igniter - the Tecs have igniters on the motherboard, and the MS does not. Very common. Lots of shrink wrapped solutions for this issue on diyautotune.com.
