Re: For those that "upgraded," ideas on stock boost gauge?
I know the stocker is way slower and doesn't have any numerical increments, I think it might be run through the ECU hence the speed? I'm sure you could wire it up to run directly off a better sensor but then you still don't have numerical increments on the gauge so I don't find it super useful.

Yes, I was very serious. I have a innovate DL32 module that measures signal from sensors. I plugged it into the stock map sensor to monitor boost. I am amazed how fast responding it is compared to my mechanical gauge that has to wait until pressure rises in a tiny little tubing. The pressure sensor is in the engine bay, so there is minimal tubing, hence minimal gauge lag. That is my experience with electric boost gauges. I never meant the slow stock electrical one.

Weird.
Not to argue or anything, but the tubing would pressurize at the same rate as your intake manifold. I would be willing to bet that what you're seeing is more a function of dampening than anything.
I have a mechanical on my Miata and it's ridiculously fast. I can watch it fluctuate on bumps in the road that cause my foot to barely move on the gas pedal. On the same topic, the mechanical in my MX6 is pretty slow. I blame the gauge, not the tubing. The miata has an Autometer made for Flyin' Miata. The MX6 has a Prosport.
I may be old school, but i subscribe to the thought of "unless you live in CA, there's no reason to have an electronic gauge.*"
*for display purposes only. If you've got some fancy electronic feeding both a display and an EMS, then that's fine. Clean way to install.

Re: For those that "upgraded," ideas on stock boost gauge?
My mechanical gauge might be slower than most. It's a Autometer Liquid 2 5/8''. Maybe the liquid in it and the bigger inertia of the needle (compared to 2 1/16'' gauges) make it kind of numb.
The gauge takes it's input directly at the map sensor signal, so it is not driven by the ECU.

Re: For those that "upgraded," ideas on stock boost gauge?
slow motor/control circuit then. I wonder if there's an easy way to make the stocker at least respond faster.

Re: For those that "upgraded," ideas on stock boost gauge?
in short no. Just like the gas gauge and the temp gauge its slow due to the type of gauge. Notice when your car is filled from empty takes forever? That's due to the current that brings the gauge up vs the others that are demanded to a spot like a stepper motor or mechanical boost gauge. Its the same desighn if you ever take it apart and look. I had to when going to jdm cluster then back cause I could not find wire pin outs on the gauges. There is room for a gauge in there and the pim wire is very fast if you bypass it like the prior posts, the map sensor/boost cut sensor needs to respond to manifold pressure asap when you boost spike past the ecu's max psi 12/17.6 psi(or whatever yours maybe)
Ill see if I can pull it apart soon and show you. I have a gts, gt4 and alltrac speedo in storage waiting for me to do this.

Re: For those that "upgraded," ideas on stock boost gauge?
Had a thought today, the gm gauges respond faster to change....maybe look into their gauge...I won't tho.

I just remembered something, when I was stuck at 6-7psi the stocker would read full boost in 1 & 2, but only 3/4 range at 7psi in 3/4/5 (which makes sense because 3/4/5 should be at 11). If it's hooked up direct, how can it tell?

Here is what i did in my 165. I didnt want to have one anywhere else.

You can fit some smaller gauges in there with some modifications, or if your using AEM ems, you can use the serial gauges to read outputs off the EMS directly
So cool
Wow I didn't know about them. That is cool. I think that is def the route I'll be going. A big plus of the AEM ems there if you ask me.

Re: For those that "upgraded," ideas on stock boost gauge?
Get a gts cluster, gut the side with the voltmeter. Install it into the trac gauges... It fits. It works. It's simple.

Re: For those that "upgraded," ideas on stock boost gauge?
This guage won`t fit on our cluster, it will overlap on the fuel and temp guage.

Right now im working on a multi function LCD screen that will replace the boost guage, basicly a small rectangular green on black lcd run by an Arduino BT board that im programming for boost/vac , water temp , oil pressure , oil temp. I`ll be able to switch the functions with a small switch that im adding to the center console. I want it to look as oem as possible.
Oh, and since im using a BT board, bluetooth will be operative so anybody with an android phone (sorry I don`t code apps for iOS) will be able to monitor on their phone and change some parameters. Keep in mind in currently in pre-alpha test, I barely finished proggramming the board and very loosely fitted the screen to the cluster. But I should be able to get V1.0 ready this summer

I believe there's a company that does something similar using the clock location.
