does alky affect egt readings??

Gnfanatic · 08-16-2004, 11:35 PM

Hey guys , got Razors kit. I am pushed the 70gtq at 26 psi so far with 93 octane and alky, it was a fulkl run. My egt was 1270, which is very rich. I heard alky will make egt readings not accurate?? Is this true. I am worried about that.

thanks]

I think your EGT guage needs a new battery

I compare EGT to one wire sensor O2's and they usually line up. Only if there is KR will the egt be higher. Example is 750's for O2's = 1600 for EGT. 720's for O2's = 1670's

Glad your having fun..

Hery Razor, my egt is good, it is a calibrated fluke meter. I have me-r, so I am going to change the pos to take some fuel out. But I heard that alky mess's up the readings with o2's and egt. I guess not??

thanks man
Ralph

By the way, what do I owe you for that filter?

My buddy has an EGT meter with the same condition.. wont read past 1250.. I swapped my meter in.. bam up to 1600's.. Sometimes things arent like one would think. Put the meter in another car..see what happens?

stevemon · 08-18-2004, 08:26 AM

and I know one that had the EGT set on centigrade, looking for fahrenheit numbers.

Razor · 08-18-2004, 08:01 PM

I hate when that happens.. wonder what 1250 centigrade is

Time for a roast..

Gnfanatic · 08-18-2004, 08:53 PM

I love my fluke, it kicks but. I as jsut running rich, thats all. I will check it out this week. I jsut wamnt to make sure that the alky does not make the egt accurate anymore. I heard this from a friend.

thanks
Ralph

no, it wasnt. I did talk to hi about it though.

The stock o2s have no meaning other than in the crudest sense.

I run my ME-R around 1600 on 93/alky-use the least alky you can to advoid detonation and then start pulling fuel. If you get any detonation before you reach 1550 or so...then wonder about your probe.

Gnfanatic · 08-23-2004, 12:29 PM

Steve, how does your me-r idle?? Mine is a little rough . my iac counts is at 13 hot in park. tps ia at .42. fp is at 41 at idle, vac off. idles a tad rough. what about yours? thankls

Steve Wood · 08-23-2004, 05:19 PM

Mine idles very well. Being open loop, they should idle as well, or better, than anything around.

I think the in gear idle is 800 on mine and 850 in Park with 75# injectors.

Gnfanatic · 08-23-2004, 06:39 PM

Damn Steve, mine runs a tad rough. idles from 825-950, slowly goes up and down. iac is at 14, tps at.40.

hmmm, guess more tuning

thanks
ralph

I got the same injectors as you to

Steve Wood · 08-23-2004, 07:33 PM

Sounds like you have some other problem...vacuum leak, or such.

Does not sound like something that tuning will handle.
