PS:

A huge Thank You to Danny for helping me, being my taxi and letting me use the workshop.

Also thanks to Simon for the spannering and Corn-Dog and the ADE boys for the wiring and welding.

Looks awesome, should be a ball of fun.

Keep us updated

Soooooo how was the drive home????

[Mokesta]

Ms Daisey would have been happy with my driving. I was very good. I need to get this thing mod plated and don't want attention until it is.

It had no trouble going up hills at 2,000 rpm.

Likewise fantastic Mokesta - great to see a couple of extra M45s on the Forum.

great to see a couple of extra M45s on the Forum.

2nded! Have had a few turbo NA/NB experiences but not the supercharged experience yet. Still, i believe it would suit the NA very well, particularly for track use.

The Wats look fantastic. Big fan

Another weekend and a little more progress.

Today I took the intake manifold off (again ) and installed the knock sensor, the oil temp sensor and oil pressure sensor.

Manifold off:


Knock sensor. It is a Bosch unit as used by the Knocksense MS system. These are too large to fit in the standard location above the oil pressure sender. So I fitted it above the alternator. There is an M12x1.5 tapped boss in the block but M12 is too big for the sensor so I made this up out of 10 mm plate. Danny (ORX626) is designing a neater unit that would be finished by now if I hadn't told him the thread was M12 x 1.25 mm Sorry Danny!


This is the spacer between the oil to water heat exchanger and the oil filter. It comes with 4 tapped ports and 2 earthing screws. It is a Speco unit. This has an oil pressure sender and oil temperature sender attached. These will be used by my Ruzic Engineering EM PRO II (engine monitor).


Still room to use standard oil filter.




I ran the wiring for the knock sensor and engine monitor through some insulated auto cable sock. The free wires seen bundled here are branched out of the sock and will be for MAP sensor and coolant temperature.


Then the sock runs to a new hole in the firewall next to an existing grommet. The existing one has been drilled out to fit the Mega Squirt MAP tube through.


The passenger footwell is still a mess of spaggetti. In this shot are the Mega Squirt, the knocksense MS box (lid off), the Innovate LC-1 wideband O2 controller, the LC-1 calibration LED and pushbutton and also my 4-fuse pack for powering all these items.
I also ran the Oxygen sensor through the tunnel, calibrated it and set up the MS to use it.


NOTE to anyone using Mega Squirt. The middle plug on the box is for "other" connections like the knock senor, launch control and the wide-band oxygen sensor. DO NOT read the pin numbers off the plug and wire things up. Instead read the MS Manual which labels the pins 1 to 16 left to right, top to bottom. You, like Me and Danny because he listened to me, will end up with the O2 connected to Pin 14, not 10 like you are supposed to.

Once that little annoyance was corrected, I started to connect the Engine Monitor.

Here is what you get (wiring harness not shown):

One engine monitor box with 4-line LCD display,
2 x 2-colour LED lights, one for 2-stage shift light and the other as a warning light when one of the alarms triggers.
1 x VERY LOUD buzzer to let you know you are just about to blow up your motor.
2 x Push button switches. One used as alarm acknowledge and the other to trigger stuff. It's programmable so it could be lap time marker on the race logger, it could be intercooler water spray or electric water pump override etc.

I got the unit connected but at night it is hard to take good pics. Here is one with flash:


And another without but with everything looking fuzzy due to hand movement: I don't like this one because it gives the impression that the screen is a bit crap. Look at the above photo to see how crisp the lettering really is.



I am going to make-up a temporary mount about here for track days and leave the unit hidden when on the street.


Right now the EM only has oil temp and oil pressure. It will get water temp when I do the coolant re-route and will get all the inputs it takes from the ECU after the car has been on the dyno.

That's all for today!

Looks like an awesome amount of work was done with great results.

Pity they didn't design that data logger as a single din unit.

[Mokesta]

It has been lots of work, so much so that I'm in the smelly stuff with my wife!

"They" (He, just 1 bloke) think the unit should be mounted so the screen can be seen without looking away from the race track. But I agree, the unit is a bit out of place.

[Okibi]

Yeah I can understand that logic, but if you had various audiable/visual alarms in place you shouldn't need to see the screen at all.

[Blue94t]

Sorry for the hijack Mokesta but these EM2 Pro units interest me, however I too prefer the single din approach.
Surely if an alarm is going off, and you know your preset alarm limits well, you would no longer be pushing at race pace. I would expect in most cases as soon as the alarm signals you would be off the racing line and slowing giving you plenty of time to deal with your low oil pressure/high coolant or oil temp/other fault. Even with the large screen to the left it still takes a lot of concentration to read the information displayed, even the dash can be hard to read when you are pushing hard on the track. I love the big warning lights and look forward to seeing how Mokesta integrates them in to the dash. I reckon they could end up looking like Mickey Mouse ears if you stick them on the top of the gauge binnacle
Like Mokesta's my car is a street car that will see a lot of track time when it is finished but I would rather not have a large display tacked on to the top of my dash/heater tombstone. I personally prefer a more integrated look.

Back on topic, Love what you are doing with your car, should be great fun on the street and track when it is finished.

Mountain Runner,
I understand your point about the GPS but I would not put one of them in my MX5. I won't even put one in my 4wd.
I really don't like things tacked on to the interior of my cars, I guess I prefer the simple, functional, uncluttered look.
I can compromise with the warning lights as they may save my engine but the shift light I would trial fit and then decide if I used it enough to warrant leaving it mounted permanently. Even the warning lights would probably end up being scaled down and incorporated more discretely.
I am guessing you are the manufacturer, any chance of a single din unit for us fussy types.
Sorry again for the hijack Mokesta

It's all good guys!.

I am booked into the dyno this Friday with Danny. We're going convoy up to Toowoomba. I can't wait to get the car tuned.

Once it's tuned and I know the MS is working properly, I'll be all over installing the EM and the Race Logger. I really want to set up some potentiometers to measure the rotation of the suspension arms. I'd love to know what the suspension is doing on the track. Also, I want the GPS and 3-axis accelerometer. Track days last 4 hours, the time I can nerd-out analysing how badly I drive could be many more times that!

I have to say though that wiring in the footwell isn't that high on my list of fun things to do on a week night!

With the SC on and some more driving skill (can't buy that unfortunately) I may be fast enough for the slowest group at Time Attack track days.

Mountain Runner
you have a pm.

Keep us filled in on the results Mokesta

[Mokesta]

OK Back on topic.

I spent Friday at T.A.S. in Cold-wet-and-foggy Toowoomba with Danny.

The guys welded a bung in my exhaust for their O2 sensor so they didn't have to take out mine.
Then they replaced my plugs with a set one step cooler. Never saw my other plugs again.
Then they got the car on the dyno. A fresh install of the MegaTune software onto their laptop and they were away.

Not knowing us and citing insurance issues, we were kept well away from the car while it was tuned. I found this a real bummer because 1/2 the point of the MegaSquirt is that I want to be able to play with it myself. Not being alowed near the car while it was being tuned meant I haven't learnt a thing about tuning it.
I would have happily paid for an extra hour of dyno time if the bloke was happy to talk me through the process.

The other annoying thing about being kept in the waiting room was that I wanted to make sure they guys sorted out the little things like idle control, hot start etc. I wanted to know how well my LC-1 O2 sensor correlated with their dyno's O2 sensor. Also, I wanted to set the sensitivity of my knock sensor. Well the car doesn't idle well hot, hunts a bit, doesn't idle at all with the AC on. They just turned off the knock sensor input into the ECU rather than let me show them how to adjust the sensitivity in the KnockSense MS.

The result is that I am very happy with the power tune, cruise tune and all the stuff when the car is going, I am quite disapointed about the rest. I know they have insurance issues, but I have just about every OH&S induction you can get in Qld and it can't be a surprise to them that some people want to learn to do it themselves.

Anyway, enough of the whinging...

Here's the power result. Stock kit, 76mm nose pulley, dodgy convoluted intake hose, not corrected for altitude, tyre pressure about 28 psi.





These numbers put it 10% down on Danny's car. Primarily due to the size of the charge nose pulley and maybe a bit due to his kit having the newer charger exit pipe and engine being a '96 where mine is a '93.

It was a real challenge to drive in stop-start traffic in the rain. The torque and old tyres making it want to spin wheels at 2,500 rpm.

My very next mod is going to be a smaller charger nose pulley!!
