Hi Folks,

This is a plug for two products I have been developing - a " Hi Definition Ignition " and a Tuning Scope I call the " Hand Held Dyno "

So, tell us some more. Will you make’em? Any thoughts on price yet?

Hi Mike,

Yes I plan to make them. Price will be revealed when I launch which is still a ways off.

I have two products that can be purchased separately, or as a single integrated unit.

First product os the "Hand Held Dyno". When I first tested it (tells you the Air Fuel Ratio, Exhaust Gas Temp & Manifold Vacuum)- on my Montjuich it informed me that the front cylinder 200 degrees Celsius colder than the rear cylinder

Watch how it works and the notes troubleshooting the problem. Video here: >> Hand Held Dyno Finds a problem <<


2nd product is the Hi Definition Ignition which is a Multi-tooth trigger wheel like on all modern cars. It will have an option for 3D ignition mapping also. Video here: >> Hi-Definition Ignition First Strart <<

Let me know if you cannot see the Videos on Facebook - I can upload them to Youtube if required.

Hi...
I recall the difference in temperature issue. Did you ever find out what was causing it?

I will try again: looks like the front is too rich — much lower air-to-fuel ratio compared to the “perfect” 14.5:1 rear. Leaner will make it run hotter. And “Lean is mean”.

Could be jetting. What size main jets are you using?

I use 165/front and 175/rear main jets on my F1 with NCRs and 41mm Dellortos

Did I win anything?

Mike. I am about to pass out from holding my breath!

What is the answer?

MikeV,

That is a fair interpretation of the of the results... but the main issue is that the rear cylinder was running @ 600 degrees Celsius and the front at only 400. (Standing in the shed)

Question 1. Which cylinder is running at a normal temperature? Front @ 400 C, or Rear @ 600 C?

Question 2. What could cause the difference in temperature?

Tip, it has nothing to do with the rear being out of the wind or being above the front cylinder.

When you watch the video you will also notice that the AFR for the rear remains steady while the front is all over the place.

I don’t have Facebook, what’s the answer?
Waiting with baited breath!

600C? Sounds like red hot to me!

I remain curious about the main jets.

Huit meant “bated”, but he got cofused with fishing. Canada. Eh?

I am in....but I can barely read a ruler......
I say the rear cylinder is too lean and hot and the front is close, but the off idle transition to the mid range is rich.


On the AFR....in the real world dont you need to be south of perfection??
