You don't have to de-solder the oled to seperate the boards, they will fold out once the board is de-soldered. There are a few points to de-solder, however if you have some soder wick it shouldn't be too hard.

IF you look at this post: http://legacygt.com/forums/showpost.php?p=2826293&postcount=142 You will see the board stack up. To change that LED you would need to remove the overlay and de-solder the interface board from the main board. I dont think you will be able to swap that led without separating the board stack. The red led datasheet is at: http://catalog.osram-os.com/media/_en/Graphics/00042116_0.pdf The white led datasheet is at: http://www.mouser.com/catalog/specsheets/Lite-On-LTW-170TK.pdf

Maybe, however the top end of the sensor will always be 125. I believe they give a rating to the sensor encapsulation of 105 due to the heat activate adhesive.

tangcla, A couple of thoughts on possibilities: It could be related to a loose connection, including at the extender, most likely. The afr line could be touching another line with voltage on it somehow, this would cause the sensor to rail. It could be a software bug for Celsius conversion? I dont think so. Is it doing this jump while driving or idle? The ambient aux temp sensor is good to 125 C the material it's encapsulated in is rated to 105 C. (221F)

Perfect! Thanks for getting back to us on that update rate. Glad you are liking the gauge. No. It is fixed for the temp sensor. The temp sensor is actually updating every few seconds or when the variation exceeds a specified minimum increment of change. The idea is to add some hysteresis and stability to the readout. You will also notice that if you encounter large temp change fast, it will keep up, however the thermal response of the temp sensor is somewhat slow due to the thermal resistance of the temp sensor encapsulation. Hope that helps!

I gotta get my hands on a 10-11 vent, so probably with the next few months. I'm not sure if it will fit in the center console vent, so it will probably have to be the drivers side vent again. Out of curiosity...Is anyone actually using the parking lights sense line? Or is everyone pretty much using ambient light detector?

PM sent

All the software is in the display unit, the part which resides in the vent.

thefultonhow, I was looking into this 'jumpy pressure' reading some more, I changed the adjustment on update rate speeds for the oil pressure aux readout. I tested it on the bench. Looks like more averaging was needed to make the three settings for fast,med,slow updates have a good range. If you want to send your gauge in, I can re flash it for you at your convenience.

Couple of examples of different averaging: [ame=http://www.youtube.com/watch?v=QSo8NcIczd8&feature=related]YouTube - Dodge Challenger R/T Digital Oil Pressure Gauge[/ame] [ame=http://www.youtube.com/watch?v=Di9qnNHwtW4&feature=related]YouTube - Auto Meter Cobalt Digital Oil Pressure Gauge in a Jaguar XJ6[/ame] look how long the delay is once the tach jumps up [ame=http://www.youtube.com/watch?v=iYb8jClJMDI]YouTube - AEM Oil Pressure and AEM UEGO Gauges[/ame] Less averaging

Yes 1.04 is needed, plus the 1.04 sending unit, which has the new aux input plug receptacle. There is a 20 charge to update the sending unit for previous beta testers. The firmware update is free for beta testers. To do oil pressure you also need a gaugetek aux adapter harness (30 bucks) and the prosport sender and prosport harness. (sold by prosport) http://www.gtboostgauge.com/VBG1 Aux Oil pressure wiring instructions.pdf I think we really just want to average it more at the slowest readout. That way the numbers will be the average of all the transients, pretty much what the sluggish analog gauges are doing. How big are the swings in fast update mode? So do you think we should tweak the average on pressure? It may be needed. I don't know the answer regarding the BPV, what I do know is the VBG1 is really good at catching transients of boost due to it's fast sampling rate. It will show up as spikes in the profile plot as well if it is a spike. I would assume the if it's not related to boost tap location then it could be a real pressure transient. Remember that when the VBG captures peak, it is a raw unfiltered peak, meaning it will catch almost anything. Hope that helps.

1.04 is out, and has been out. thefultonhow, I was doing some looking on you tube and it looks like some of the digital gauges average the oil pressure more than others. Basically what I take away from it is that oil pressure is rather jumpy. That means we are going to see variation in the digital readout unless I add more filtering. I agree, the average for the slowest update setting should be larger if your saying it looks jumpy. Less accurate? Not really, but because it is an average however, time is involved. So it depends on how you judge accuracy, at an absolute point in time, or over some time frame. No, most likely the transients of the pressure are dropping below the alarm threshold. The beta testing for 1.04 is closed. Yes the gauge accepts one input: AFR via LC-1 Ambient Air temp (sold by gaugetek) Oil pressure via prosport oil sender (PSSMOPS) (adapter harness to be sold by gaugetek)

nope, it was requested after 1.04 was finalized

This could be implemented in the 'swipe down' (blackout) feature: one swipe = OLEDs off (bar graph LEDs on) swipe again = ALL off swipe again = ALL on

I should have a few back in stock by Monday. thefultonhow, the slowest data update rate takes a 10x sliding average of the oil pressure. The display is always updated at approx 10 Hz. The update rate is pretty much a software filter, I implemented it when I was tired of watching vac numbers jump by so fast. There's accuracy and then there is useful accuracy. It's possible the highest level of filtering for oil pressure is not high enough for some users, to be honest I dont monitor oil pressure in my car so I was relying on beta testers as a feedback point to what works. Since I dont display decimals for oil pressure in the units of PSI. I'm thinking you mean it fluctuates between 76 and 77 when it's right on the edge (between 76.4 and 76.6). There is a bit of Hysteresis built in however the value may be too small, or should be larger when the slowest 'update data rate' selection is selected. Do you see a difference between the slowest and the fastest selection? you should, and if so I bet the fluctuation is larger, is it? I can make changes to the filtering for oil pressure if we think it could be improved. Other oil pressure beta testers, what do you think?

I have done some testing. The 4 conductor should work fine as an extension. The 3 conductor is electrically compatible but is not recommended, because the contact locations could be non-ideal and cause intermittent connections. I will ship all the new temp sensors with 10ft 3 conductor 2.5 mm plugs. I will also carry a 6ft extension for the temp sensor as an option.

I got one on order this morning, I will keep you posted. Thanks for the feedback.

I looked at my records, looks like you have version 1.02. Back then buttton re-calibration was done a little differently, so I'm not surprised you might get lock-up under extream conditions of humidity/temp swings. In version 1.03a I think all of that was fixed so even if it locks up. it will un-lock it self. within 20 secs or so. The vent is a harsh place for this thing, but it's just part of the challenge to make it look good and work. Firmware upgrades for beta testers. Sure, whenever your ready, PM me, send it back, and I will get you the latest loaded up. If you want a new sending unit (for aux sensor temp or oil press) that will be extra, but if you just want the display unit re-programed...free for beta testers. I ran my temp sensor through the firewall here. I guess that is not an option for manual transmissions. How much longer do you think you need it to be? I standard 4 conductor 2.5 mm audio extender should work, the 4 conductor versions are harder to find, I will need to order a 3 conductor and check compatibility, it think it will work fine because of the pinout of the sensor. If the 3 conductor works my only other concern is where that extension connection resides. My guess is your going to say the fender, if so, it could be a bad place for a connection unless you seal it up well.

Correct! Did the gauge say "wait" in the vac screen? It probably did, you have to wait for the boost profile to complete before loading. meaning if you stab the throttle, then request peak immediately, the gauge is waiting for the 5 or 10 second profile to complete. Currently there is no option to shut this off other than disabling the aux input. Out of curiosity what does the oil pressure plot look like during boost? Steady? Someone mentioned fast and jumpy oil pressure readout, did that slow down with the digital update configuration setting? me too! I blame it on testing though.

Yes I plan on selling the sensors separately as well, they can be found under the 'sensor' section of the http://gtboostgauge.com/shop/ site.

Thanks for the feedback thefultonhow. How much longer was the pressure harness than needed? I had no idea how long to make that. The gauge will also re-activate if the any of the alarms trigger. So if you set a low pressure alarm, the gauge should always notify you. The oled timeout can be disabled however it is recommended for oled preservation. Changing the display rate in the options menu should help filter the vac and oil pressure readout if you think it's updating to quickly.

Version 1.04 beta is shipping to a few beta testers.

Maybe, but it's too late for version 1.04. That one is locked down for changes. Oh just so you guys know, the menu configurations have changed a little bit for the latest version of SW. V1.04 - see the new manual for details: http://www.gtboostgauge.com/VBG1%20-%20Manual%20for%20V1.04.pdf

a few more videos of version 1.04 beta. Trying to wrap this version up and get it off to some beta testers. Complete version feature post to come. [ame=http://www.youtube.com/watch?v=0yvNljJUmWw]YouTube - BOOST DEMO - VBG1 - VERSION 1.04 with NEW Pivot display and alarms.[/ame] [ame=http://www.youtube.com/watch?v=IOsJa6f6DC8]YouTube - ALARM DEMO - VBG1 - VERSION 1.04 with NEW Pivot display and alarms.[/ame]

Ver 1.04 will now have alarms on aux. (pressure or temp). Also implemented new alarm on volts. Also new alarm menu to quickly adjust alarm parameters. more later...
