Is the thermocouple for head temp a sparkplug washer or coolant probe?

Data aquisition is the only way to go. It will show you how far off your set-up is. The one i use has over 20 channels on it. The coolant channel will show guy how hot these motors run.

all of the Digitrons I have looked at us the plug washer for head temp. Saving my pennies to get one with the dual EGT leads so I can also use on my RZ. Glad to see Stewart has one and will learn from him some of the pros & cons such as head temp droping & EG temp going down as a signal it's almost at a melt down stage. Can't wait!! :-D

skip your hvac project and buy a nice data logger.

Does this set-up have a alarm or light that blinds if it goes over preset limit for the sensor reading. I think it would be hard to read the screen in 5th gear.  I wouldn't trust the egt reading melt down protection. Det. sensor would be the better set-up.

Any other members here using similar setup??? If so, can you post your trial & errors, also what you learned from the info collected.

Detonation will cause EGT to drop FAST!

I lost a motor last year and my egt never increased or decreased. But this motor runs at 15% det. all the time for most power. I just part throttle it too long it went. It depends on your compression and timing what you get for egt reading too. I can't post video on here of my data logger runs, but i did email it to doug.

Doug,

When I ordered the system, the folks at Digatron were super helpful and even changed a few things around to help focus the system on land speed instead of kart racing.....ommited the lap counter, etc.

They also offer an thermo sensor that mounts in-line in the coolant system.

Please check your pms Doug....

The eight ( 8 ) lights on the right side of the instrament face are all programable to respond to any preset limits or minimums.

As far as reading the gauge WFO....you know that Stewart builds motors that are smooth enough to ride with one of your grannies tea cups and it's matching saucer on top of the gas tank!  :-D

Do you guys know the response rate for the sensors that you use? Brand?

I am really excited about taking this program to the next level with the Digatron!

Mark,
Checked PMS (nothing new). Did you receive mine with the Tracking Info?

I am Very much looking forward to the implement of this Data Collector (In the Hands of someone like Stewart) so I can learn myself (hopefully) on the Proper way of using this device & info. As stated previously, I am saving my $$ to get one & have tried to read up on this things online & all seem to like the Digatrons best.
Correction on my previous post:
EGT going Down With Head temp going up is the indicator that it is near meltdown (heat taken out of exhaust & put back in the cylinder/at least thats what I have read).

How does the o2 sensor get along with premix?
