Hey Guys!

I'm not sure what to do! I installed a Autometer ultralight analog gauge last week. Everything was working perfect, boost showing just under 15psi with the occasional spike to 16psi, this is at ambient temperatures of around 65 degrees F.

I am running V2 with a dual cone intake, my user settings on the V2 are 92%.

Yesterday and today the temperature climbed into the high 80's and my car started showing sustained boost at 20PSI!!! I almost shit myself. I hooked up the laptop and dropped the settings down the 88%. Car felt slower but was still showing high boost on the gauge. Then I did a couple data logged runs, and the procede software showed max boost of 13.8psi, even as the gauge was showing 20psi...

I have my gauge mounted at the T between the diverter valves.

Is it possible for Procede data log to be wrong??? Or for a brand new analog gauge to show perfect one day and then be so messed up the next day...?

Any help would be much appreciated!! Shiv if you could chime in that would be great too!

Upgrade to v3 (v2-v3 upgrade for $375) for no more boost spikes (and smoother power)...

nice, feed the cash cow! LOL j/k

it's a good bump in power from what i've heard, as long as you don't shred your impellers

[pino335]

You must me getting a kick-back on all V3 upgrades...lol

This isn't a spike in boost this is sustained 20+psi on the gauge..

This is why I have talked about getting a boost gauge if you have v2. You are not alone. I upgraded to V3. V3 is excellent and hits boost targets perfectly.

The thing is, on the data log it's only boosting 13.8. Is it possible for the data log to be wrong ?

I believe so. There was an issue talked about around here that it would not show anything over 15.5 or something like that, so if you were using the data logging you needed to keep lowering the user tq values until you were below 15.

I would not rely on the data logging. Put it to you this way, with v2, I saw 23 PSI at one time and lots of 18 and 18.5 at 94% on a 95 degree day with a VEI digital boost gauge. Shiv made his prefernce known for a mechanical gauge over digital, but I am using the same gauge now with v3 and it's hitting boost targets perfectly so I do not think there is anything wrong with the boost gauge. (I was not measuring spikes at shift points, it was while in one gear).

This was my original post on my experience just after I got the boost gauge installed. http://www.e90post.com/forums/showpo...0&postcount=21

V3 now monitors Intake Air Temps and adjusts accordingly and also has an additional safety routine running to make sure there are no unsafe spikes. V3 has been flawless to date. I'm a happy customer.

Wow i'm surprised to hear that data log will only show a max of 15.5, that is really taking a risk... I hope everyone running V2 knows this!

I'm going to go do a run right now and play with the settings.

[scottp999]

I went out the day after to adjust mine. Took it from 94 setting to 88. Only problem is that the next day it was 20 degrees cooler, so if the temps were the same, who knows how much I would have needed to lower it.

I'll be quiet now. I've talked about this enough and I'm sure I'm not making some people happy.

I think it's good we talk about it, just think if someone's not running a boost gauge on v2 and the temps rise! (presuming that this is the problem)

its not thats its wrong, its just reading it from a different place than the boost gauge. (IC Vs manifold.)

But yes, run several back to back runs with minimal cool down. You are supposed to adjust the settings for a worse case scenario, like ambient temps being raised. Guide yourself off of the boost gauge and not the software. And if i were you, i would calibrate that gauge just in case.

This is one reason that cars with good intercooler upgrades will see less boost than cars with stock intercoolers. This is also the reason that you see less boost in cold ambient conditions than you do in warm conditions. Until you do a run up through the gears, of course. At which point, IAT is substantially higher than ambient temps.

Does boost pressure raise with ambient temperatures. Concrete, if a PROcede V2 user now sets user torque settings for a 15psi tune ( 94% ), will this user see more than 15psi on hot summerdays ?

Or is it the other way round. Colder ambient temps, more boost. This would be logical, because the air is more dense. The question is what does the ECU / PROcede V2.

Thanks,
Eugen

Meaning that it will harder to induce boost pressures over 15psi even ambient temps were to increase significantly. Not something I've mentioned because I don't want people arbitrarily jacking up the numbers and thinking that they wont run any more than 15psi.

Yes. I agree. I just don't want to be the only one talking about it all the time. I do not know how many V2 customers are still around though. All new orders are v3 and there lots of v3 upgrades from V2.

+1 me too!!!!

[pino335]

Well i just did a bunch of back to back runs.


Here are the results with different settings: (AmTemp 77 degrees)


92%

Gauge: 25psi+++
Data log: nothing over 14.1psi


0%

Gauge: 10psi
Data log: 9-11psi with a couple of 15's mixed in randomly...


50%

Gauge: 12-13psi
Data log: 13psi


80%

Gauge:15 with short spikes to 16psi
Data log: 14-15.2psi



So it looks like the gauge is right. I'm shocked at what a different ambiant temp makes. As the temps rise this summer, this should serve as a warning to anyong runnig V2.

*************V3 ORDERED**************

lol

Anyone know how long it'll take??

+1 and anyone running a high-end tune should have installed a boost gauge before the tune. Boost gauge should be performance mod #1 if your buildup includes increasing boost.

[1cleanm6]

dude...

the v2s and stuff scare me.

[slow_335]

Does anybody else think this is a big flaw in V2 and customers should have received a free upgrade which corrected these issues (aka V3)?

question on this, any vacuum source will be from behind the throttle body. Vacuum being produced by the closing of the TB and the engine still rotating sucking in air. If you tapped into the IC lines instead its possible to see boost but not vacuum. IMO its best to take vacuum off sole sources meaning not a lot of vacuum t's. I have seen too many items t-ing off a vacuum source reducing the reliability of the readings.


v3 sounds nice, so whens v4 come out lol just kidding

[lawdude]

Hey LAbeemer, let's see a picture of your motorcycle.

[v2bling]

On my car it stays at 15 psi max all day at WOT.. You will LOVE v3. I have the upgrade version. The boost control is so smooth. Its like stock again with way more power.

Ive used jb2h, so i know both tunes. This tune is way way smoother then jb boost control. But you know that allready haha

I have not had one reduced power since v3 has been on it. Feels weird almost lol Everyone should get that better quality black tape dustin uses. It really gets the connections stable
