KillerBee ('92 with '00 engine Coldside, Megasquirt, WI)

[fourwhls]

I finally got the bee to the dyno today. After overcoming some serious headaches, we finally got a descent tune on the car. I still think we left a little on the plate, but I am happy with the results.

A little breakdown of the car....
1992 Sunburst Yellow A package (2050lbs before FFS)
2000 1.8 Engine
440cc RC Engineering Injectors
Megasquirt PNP
AEM Water Injection

I set the cam gear back to 0 deg before the dyno. I'd like to head back and play with them and see if I can get the torque up a little.

We tuned it to 11.8 on 93 octane. It was much happier into the 12s, but being that it will get abused on the track, we took the conservative route. I stopped the pulls at 7100ish rpms. I have the rev limit set for 7500 and have been known to bounce of it in the past. So running the current plot into the 7500 range should have put me in the 225-230 range.

The first plot is the final run today. The 2nd plot is an overlay of my last trip to this dyno along with today's plot. Just a little change. :D

Nice. 121 stock was not bad either.

Should be another car with the MS coming on line soon.

[Toby Weir-Jones]

Pulleys, boost, etc?

Which exhaust manifold is on the car?

twj

[fourwhls]

115/65
201 kpa (14.4 psi)
Custom airbox with K&N (another thread with details is out there)
Racing Beat 4-1 header
very little exhaust...Header to small resonator and exits before the rear end. (yes it's LOUD)

How did you hook up the MS PNP ?I thought that the pnp was limited to 94-97 or something like that ??

Where is your WI nozzle located ??

[fourwhls]

There's two versions of the MSPNP right now. 90-93 and 94-95. I don't think they have a 96-97 yet.

The WI nozzle is located where the 5th injector would normally be located. It appears to be working really well right there. At 14 psi, my intake temps were 106*F.

I was wondering how the 2000 engine played into this ??

I am still running 1.6 wiring, so I used a MS for a 90-93. Although, I am running the 2000 TPS and IAC, 94-97 alternator, and numerous other parts from different year cars.

Needless to say, I created a nightmare. Life would have been so much easier if I would have just stuck with a similar chassis and engine. I made this install much harder than it should have been.

Wow, great power and that is a really nice torque "curve"!! :biggrin:

[gludlow]

Looks great! I bet it's a blast to drive. And I love the colors :)

[Gord96BRG]

That is a very impressive result!

Any chance you could post the table for your timing advance numbers? I need to re-tune my Link now that I have the WI running, and I think I'm currently leaving lots on the table with my current timing map...

Gord,
Here's a screenshot of my timing map. Please only use it as a reference. I know it still needs some work. My full throttle cells are on the money, but the rest need some tweaking.

[Gord96BRG]

Thanks! I'll have to dig out my laptop and check my timing charts... and check my kPa values for the table!

What is the kPa scale referenced to? I'm guessing that the bottom row is your high boost row, but then the scale is backwards to MAP?

[fourwhls]

Actually the 3rd row down (184kpa) is my top row being that I saw a max boost of 204kpa.

I don't know how you will translate those values into the LINK, but I'm sure you'll figure it out.

[Gord96BRG]

Ah, OK, that makes sense. I still haven't looked at my table, but IIRC the Link only has 4 rows in vacuum, then 3 rows in boost (and I haven't used the highest row yet). Your timing at high vacuum (bottom two or three rows) looks to be using quite a bit more timing from 2K up than the Link defaults.

I'll post back once I've had a chance to compare.

[JTod]

Looks like the attachments went away - maybe when the forums blew up? Anyway to get them back? I would like to see these charts as I am contemplating something similar. Anyone remember what the numbers were? Thnx

The server that I had the pictures hosted on is having issues.

I have attached the dyno with before and after results.

[Tom @ Fast Forward]

Attachments are still there for me?

The pictures are missing in the first post but they are links to an external website not under our control.

[V8KILR]

Nice. How do you adjust cam gears and how do they work?

Thanks for reposting! Great results!!!

Are you using the Megasquirt to control your W/I?

Not yet...I am using an AEM progressive kit. As soon as somebody comes up with a REASONABLY priced high speed valve that will work with the MS, I will try controlling the WI with MS.
