multi gauges

[LETZRIDE]

Anyone use any of these? I've been trying to conact innovate, but I am not having any luck.

I want to pick up 2 TC-4 amplifiers and run 6 EGT's...one in each header piece coming from the cylinder. I'm trying to figure out if I can cycle through the 4 egt's pure each amplifier with just one XD-16 gauge from them...anyone use these or have experience?, not sure if I can get away with only 1 gauge, to read all 6, or if the gauge will only read 4 at a time and therefore I need 2 gauges?...or maybe it can't read the same perameter on multi channels?

Re: multi gauges

innovate makes a multi gauge (xd-16) in which you can view several parameters on one gauge (I.e afr, egt's, different temp etc, all at the push of a button...you can cycle through them)

They have an amplifier (tc-4) which allows 4 egts to be plugged into it and monitored through there PC program logworks.

I want to run 1 in each cylinder, so I need 2 of these amplifiers along with 6 egt probes. I want to be able to monitor these while in the car and driving, even when I don't have the laptop with me....but I don't want to look like an airplane with 6 gauges plus my afr and fuel pressure gauge sitting everywhere in the car.

Now, I know the multigauge is compatible with the tc-4 amplifier, but I want to know if it would display all 4 of the egt's from that amplifier (and maybe even all 6 egts, because the two amplifiers will be daisy chained together)

I believe they say you can view up to 32 parameters, but what I am unsure of is if you can view the same type of parameters. I.e can I view egt1, egt2, egt3, etc...or can I only view 1 egt, then the other parameters are like afr etc

not sure if that makes sense lol?

Re: multi gauges

I have a rough idea of what you're talking about, but why don't you use one gauge and amplifier per left or right bank?

Re: multi gauges

been doing alot of reading on individual cylinder tuning...I would actually ideally like to run 6 widebands, but it's wayy too expensive...EGT's I can use and still get the job done...although I still have a bit of reading to do on them, they are fairly straight forward though.

Consider this...most people (shops included) are tuning cars as if the engine is a whole...everyones tuning as if each cylinder gets the same amount of air...it doesn't, no engine does. When you command lets say a 12.0 afr cylinder 1 might be getting 13 afr, cylinder 2 might be getting 11afr, and so on and so forth for the other cylinders...the average comes out to be 12.0 afr which your wideband in the collector tubes reads.

Because you have some cylinders that are rich, and some that are lean, and some that are correct (maybe), you are not getting the optimal power/efficiency out of the car.

now consider this...pull 3-5 hp out of each cylinder by tuning it individually and getting it as close to your desired afr as possible and guess what? on a v6 your going to get a 18-30 hp increase. 3-5 hp out of each cylinder is not ridiculous or wishful thinking by any means either...and we can tune each cylinder with hp tuners skewing function...we just can't control individual spark per cylinder, which would be nice and allow us to unlock even more power.

Now running just 2 egt's left and right is better then just tuning the engine as a whole...you are still getting the average of 3 cylinders each side. But why not get the most out of the setup...plus I want to be able to monitor everything for the ITB setup if it ever gets finished...

Re: multi gauges

If this is the case, then you're going to make more work for yourself than you want. Get a F.A.S.T. system, repin the harnass to comply with it.

Re: multi gauges

F.A.S.T is a standalone no? don't want to go standalone unless I can get rid of hp tuners, and I can't do that unless I can find something that controls the transmission as well (that isn't 800$)

Even if I did ditch hp tuners and went standalone...I would still need the sensors, and the amplifier to convert it to 0-5v readings...

I don't want it to sound as easy as Im going to say it now, but you can essentially use both, the FAST for the timing, fuel, and tuning, and the modified GM PCM for the trans. The issue would be separating one function of the PCM to the function of the FAST. You would have to group which sensors do what function to control what action, and separate them to the FAST system.

I have never seen it done on these cars yet, but common electrical knowledge would dictate it could be done. Not an easy task though.

I was looking into the fast stuff, but man, its over a couple grand in parts, and yes, I could keep the factory pcm to control the gauges and the transmission and just use hp tuners to tune the transmission parameters...BUT, if I go standalone I would like to recooperate some of the costs by ditching hp tuners.

^^ and everything you just said was what was making me think about the whole 4.3L pcm working with our cars in conjunction with ours. I still don't understand how if we added an extra obd II port so that you could talk to the 4.3L pcm seperatly, why it couldn't run the cars engine parameters. I see it being the exact same thing, only instead of using a standalone ecu, you are using a 4.3L ecu.
