So I just finished installing a Podi oil pressure/boost electric stepper gauge, and I have a couple questions. 1) Does the boost gauge always wait like 3-5 seconds after ignition to "dial"? 2) the package included numerous "extra" pieces. Do I install the air filter, or is that for other applications?
Where do you have the gauge wired to for power?
The filter is designed to be installed on your boost line, before the sender, to keep the sender clean. Any other extra parts you don't know about?
Thanks for your support [up]

I have both the oil pressure and boost on fuse taps. The oil pressure fires up right away. But the boost has that small delay.
I will install the air filter. In term of "extra" parts, I got a T barb fitting (I assume for 1.8s), and an extra set of hose (maybe 5 feet in addition to the 2 foot piece I used).

Yes, mine takes a couple seconds to spin up, not really an issue though

The gauges should sweep together and if the boost 'lags' a bit then it is possible that it is waiting for a signal from the boost sender which is not powering up at the same time. You can try connecting the sender +12V to the same spot used to power the gauges and see if that fixes this issue.

The air filter is used to prevent any debris from getting into the boost sender, it is optional and not required for proper operation.
The 7' of vacuum line supplied is a standard item in out boost gauge kits in order to make sure there is enough to complete installation.

So after driving yesterday (the first time with the unit installed), it worked flawlessly. When I shut the car down, I notcied the the depower is also staggered. I will take some video of it today and post here.
I actually DO have the sender and both gauges ignition coils going to the same power source, so it cant be a delayed power I will reinspect and confirm all the wiring again.
Again, im not overly bothered, as the boost gauge appears to works fine. I just didnt know if this was problematic or would indicate a problem in the future.

Well, funnily enough, this morning, both dials pegged on startup simultaneously. However, they still do depower staggered. And if I flip the ignition on, then off, and then on again (quickly), the delayed stratup on the boost reoccurs. Is this normal? As I mentioned, Im not overly worried, as they function fine, and I cant think of WHY I'd need to turn the ignition on and off like that, but Im just trying to understand why it does it, make sure its not a problem, and understand it better. Thanks.
Oh, and Winston, I have one more question about the oil pressure gauge. Not that it matters now, as Ive already plumbed it through the firewall, but the power is intended to go in the cabin or engine bay? I put it in the cabin to be safe, but I wasnt sure.
Thus far, Im thrilled with the unit. My only recommendations/feedback would be for 1) a longer lead on the boost gauge wire (to go to power, and to the sender), 2) a torx tool to get the steering column top off (bought to that didnt reach before I just drilled the facade wider on the lower shround), and 3) some better directions included with the unit.

Digital gauges usually lag, the stepper gauges are kinda like a hit or miss I guess depending on your power source. I know some people's that lag and some that don't. I dont think its an issue as long as it works fine after a second.

Cycling the power that quickly is not good for any electronics and can cause strange issues.
In regards to the boost gauge the unit does have a shut down sequence and if this sequence is interrupted it can cause a needle offset when the gauge is powered back up.
So is what you are seeing normal? That is hard for me to say as I have not gone out of my way to blow up a gauge by cycling the power that fast many, many times. I have done rapid power cycling to test gauge installations in the past and know things can happen as I have reset programming in wideband AFR controllers and electronic boost controllers as a result.

The sender can be wired up in the engine bay or in the cabin, the choice is up to the customer.

Your suggestions have been noted.

a torx screw driver for the steering is a good idea, its a really small bit and hard to find at hardware stores

Yes, it seems to be operating as expected now. I only "cycled" the power because of the unusual startup sequence, and as I mentioned, have no reason to think I'll ever do it in real life.
Thanks again and I love your product!!
