Default UTEC "Tuna" + EGT

I received my tuna today, and noticed that the analog inputs on the back, are 4-pin inputs. The EGT gauge/probe kit I have, has an 8-pin connector (of which it appears 5 wires actually run into it). The EGT kit is made by Auto Meter (part 6144). My question is, is it possible to modify the existing kit to interface with the tuna, or do I need a specific brand of EGT to interface with it?

Thanks

I'm pretty sure the UTEC does nothing with EGT signal. Sounds like your struggling--better cut your losses and sell it to me for $350

The Tuna (TXS Tuner) does have accessory inputs for devices like EGT...he is not talking about the back of the UTEC.

Talked to Phil, then Mark at TXS. He says that as of right now, an off-the-shelf EGT will not interface with the tuner, due to the difference in voltage and (obviously) the mis-matched pinout. They are working on creating an adaptor that will do some "line conditioning" (his words), so that EGTs will interface properly. From what I gather, it looks like the solution here is the only viable one for now. Time to make a trip to Radio Shack. Oh yeah, Mark also said that the 4-pin connector is simply a standard 4-pin molex (nothing special).

I have been looking for this 'standard' connector, but without luck. There are probably more than 1000 connectors called Molex connectors, since Molex is a large manufactor of connectors.

Those are not the right part. Have you even looked at the back of a 'Tuner'?

You linked to pages that have the 'Molex' connector used in power supplies, as well as the larger 'molex' 4 pin square connector. As I said, the term 'molex' refers to a LARGE number of connectors.

Radio Shack sells 2-pin molex connectors (.093"), but they are too large. I belieive the correct connector is the .062", but I am awaiting confirmtation from TurboXS.

If you talk to them, maybe ask them what part # they use and where they order from? I'll probably end up doing the same before long.

I don't have my Tuna with me, so someone else who has theirs handy can confirm. Here are the datasheets for the .093 and .062 molex connectors:

http://www.action-electronics.com/pdf/mo093.pdf
http://www.action-electronics.com/pdf/mo062.pdf

The smaller (.062) 2 pin connectors are .340 x .190"
while the larger (.093) 2 pin connectors are .540 x .250"

I believe the connectors sold at Radio Shack are the .540 x .250" ones, but will have to verifiy when I get home. If it turns out that the .340 x .190 ones are correct, I will order 50 and distribute them if you need one..

Also this page has the 'Mini-fit' Molex, which are even smaller I think..
