Who has a EGT gauge or the ability to view it????? And tell me why it is important to you please.

 

i have two pod and one of the holes will have http://www.overboost.com/obs/product...40&sc_name=EGT

easy way to view if running lean or not
i lke the above gauge cause it has built in wearning light.
i will also buy fuel pressure in the same line of gauge.

 

I have way too many gauges for another one. But I could link an option on the blitz since I am double on a few.

 

Gary,

You are in need of SERIOUS!!!!!!! help. Unless you cease and desist from all modding immeadiately I will be forced to gather a team and initiate a full blown intervention.

if you put anymore instumentation / data logging equipment in that car its going to take a team of NASA propulsion engineers to monitor all the info.

that why i got two pod it starts to look cluster f*cked. anyway hp datas logs. serouisly, fuel the most important then.........what

 

With the advent of cheap and accurate AFR meters, There is no use for EGT anymore in a 4 cycle engine. 2 strokes are a different story. Even at GM they only use them now on development engines to measure variation from cylinder to cylinder and catalysts temps.

Save the temp reading for something more important
This would be my ranking pics on a FI car for displayed items.

Boost
Fuel pressure
Air Fuel ratio
Inlet temperatures

I agree. Although high EGTs are a guarantee for knock (sufficient condition but not only condition), keeping EGTs within some prescribed range is no guarantee for knock-free running. For example putting too much ignition timing lowers EGTs but increases the chances of pre-ignition or knock.

Good knock retard monitoring all one needs for the overall say. Then reading plugs if you suspect one cylinder is running lean from a bad injector. If you're building a top-speed Nevada shootout or road racing car AND using cat-convertors, then EGT tuning on a bench is recommended to set timing, A/F ratio, and possibly boost to catalyst-friendly temps. For example, if one is running so much boost that little ignition advance is used, then it's likely EGTs will be way way high; the EGT will allow you to lower boost/increase timing until STEADY STATE EGTs to be in a safe range.

An A/F gauge reading narrow band sensors to me is mainly good for checking to see if the pipes preceding the MAF has blown off/clamps worked loose after an exuberent run. A fuel pressure gauge is extremely important to monitor degradation of fuel pump output from BOTH alternator degradation and fuel pump degradation. Boost/vacuum is not that useful if you're confident about the belt friction on SC models and on turbo cars however it is an important gauge to monitor boost creep or exhaust leaks. Inlet temps are good to get off of a scanner and good for monitoring charge air temp drops with any IC and/or turbo upgrades.

 

Wide band AFR.
AEM,LM1,Zeitronix all make excellant wife band AFR, very accurate and fast.

Also look at the FJO Electronics AFR meter.... it has a large central digital readout and a series of colored LEDs around the perimeter that sample 200/sec.

 

Thanks Phil..............got them all covered.............with gauges and data

 

EGT is useless. Just get a nice WB O2 setup. By the time your EGT's are too high its usually too late. They are really just as useless as narrow band O2 a/f gauges.
