What is max egt when tuning on nt pistons

[bkblazen2003]

what engine temp should i not exceed on nt pistons when tuning.

Where is your probe?

 

[bkblazen2003]

no probe. i'm going to tune with datalogger and safc2.
You can lean or richen the mixture and it will effect the egt.
If i know what max temp to run i will know the leanest i can run the car.
I want to tune this way because i'm using the n/t ecu and have no knock sensor so i figure i can atleast make sure to keep the motor around the max operating temp with out causing damage.

BUMP, I have a 90 NT and an autometer egt kit. mine reads a max of 1600, i also will have nitrous, I have not decided where to place the probe yet....

i really need advise on this. Even if you have a turbo ecu let me know what temp are you logging while maintaining zero knock. remember n/t pistons

your guage has a max of 1600 or you car is running at 1600.
but i don't think this will apply to me because my car is turbo with n/t pistons.
i need the temps that someone has already ran at with no problem with about 10 psi.

WTF? You are talking about EGT temps and you don't have a EGT probe.. You are using SAFC which only senses O2 voltage on the exhaust side...

Your probe is supposed to be on the #4 runner for the best temp.

You should fill out the rest of your vehicle profile. But after reading some guides off of 2gnt.com I belive the max EGT temp for N/T's is like 1450. Wouldn't go past 1400 though. Because your turbo'd it could change, but thats what I read. As for not having a knock sensor I wanted to ask you if you check out the ECU pin diagrams for your model year.

My car is a 99 GS, and I found a knock sensor pin when hooking up my SAFC2, I'd double check with mitsubishi's shop hand book.

we have knock sensors, but the safc will not read the signal ours produces. the ecu uses it to adjust timing as necessary tho.

the datalogger reads engine temp so wouldn't need the engine probe.
so if i plug in a knock sensor on the pin the n/t ecu will send knock info to the datalogger

Everyone calm down, all that happened was the assumption that engine temp was EGT, but heres the truth:

Engine temp that a datalogger reads is really telling you the water/coolant temp. You can not tune your car with this data. Your pistons will melt way before you notice any kind of small spike in your Engine Temp. if you notice one at all. i wouldn't let this exceed 255*F.

EGT stands for Exhaust Gas Temp. You have to have an aftermarket EGT kit to see this because our cars do not have one from the factory. This data will tell you indirectly whats going on with your A/F raito and weather you may lean out the engine more or richen her up. 900* C or 1600*F are the max safe temps for most engines our size. Some people will tune to reach 850*C at the top of 4th gear to be safe.

An aftermarket EGT kit will include or require the use of an EGT probe.

For mild setups and mods The EGT/Datalogger combo will work well, but after spending all the money for the EGT, SAFC and logger equipment you could have looked into reprogramming the ECU (not sure with the N/T cars but DSMlink would be perfect for turbo cars)

Also, you may want look into the Wideband o2 sensor systems that are coming out. This will allow you to know your exact A/F ratio and make tuning the car easier.

Got It?
