TST question.....

[Triton]

I would call them but, it's Sunday ;-)



I'm wondering if the R37 and the CR49 are the same programmers only the 49 give you the gauge readings.



In looking at their site it says the R37 does not adjust rail pressure and does not have adjustable timing advance.



The CR49 says it does but, just not for the newer models yet and a upgrade will be supplied at no extra cost when available.



I already have gauges so I really don't need to spend the extra cash on the CR49 but..... if eventually it will have the adjustable rail pressure and timing and the R37 doesn't... . would it behove me to buy the 49 ?



I'm still learning about these programmers and do plan on a Smarty also. Since I will have a Smarty, will the R37 be all i need ?



I hope that all made sense..... thanks for any help.

You will want to have the R49. The EGT-based defueling is worth the money. It's too easy to get carried away and not monitor your EGT's. When the TST pulls back it reminds you that you're playing a little too hard.



Good way to keep valve seats from dropping and pistons from melting...



The gauge functions and rail pressure are just bonuses, IMO.

Ditto the R49. I will be upgrading soon. The adjustable timing would be nice.

R49 is the best way to go.

It give you all the functionality you need for all your mods...

If you spend the money on the other one now, you`ll be back to get the R49 later. :{ So buy the R49 and save yourself the headache... .

Triton, R49 is already available with adjustable timing and rail pressure control (I have both and I am no one special). They have also released multiple tune control. Their website must not have been updated recently.



IIRC in order to upgrade to adjustable rail pressure/multiple tune/adjustable timing, your PMCR module must be above serial number 5000.

thanks for the info guys ! I guess the question now would be..... since I already have a analog gauge, is it possible to just splice the TST pyro wiring into my existing wiring and have them both work ?

I asked the same question to TST. Their answer was that splicing was not a good idea, the signal would be split and it would give you erroneous egt's. I asked if I could use the probe that I already had installed in the manifold and they said their gauge is set to the probe that is delivered with the kit. I opted to install the additional probe and am now monitoring cylinders 4, 5, & 6 with the TST and 1, 2, & 3 with the analog gauge.

Thanks Avi. I like your idea of just installing there probe too. So, do you have a probe at #3 and one at #6 ?



Are you seeing big differences in the temps between the 2 ?

I have the ATS manifold, I used the predrilled location provided by ATS for the analog gauge and I drilled and tapped just above the conection to the turbo in the neck for the TST probe. The temps do vary, but there is no ryhme or reason. Sometimes one is hotter then the other and then sometimes the other is hotter.

I have both analog and TST pyro sensors installed. Analog sensor is in top of manifold between 3 & 4. TST sensor is about an 1" away toward # 4. My readings are generally the same within +-25*. The TST digital gauge is a little slower to respond to changes on hard acceleration or load, but will sync up with the analog gauge in a second or so.
