You can see AFR changes at the full 2ms. But, they do not get all the way to the actual target value until, at least 6ms. Good enough to pick out per-cylinder variations, on a scope.
There is no good way to do the flash operation, without the test/programming fixture.
This is great that you have done this I have the 30-0310 and would like to get the patch once you have it, I think this will let the new MPVI2+ work standalone with Bluetooth as it currently will not work with analog and that would be great as I would not need the laptop anymore for tuning.
Let me know when you get it.
Thanks for the great effort and work you did for this.

Yes. I can still update 30-0310s for OBDII.
My message box was full, earlier. Made some room.

Hey - what's the difference between this firmware versus the 30-0334? I don't need the gauge as have a Motec C127 dash thats using the OBDII data and some extra sensors to drive it, and if the 30-0310 can be setup to "talk OBDII can" onto the same bus that means the dash can see it, the MPIV3 can see it, and it's a nice tidy package.
Thanks for offering this!
It is, mostly the same firmware as the 30-0334. But. it has no user interface/display. So, if you want more than 1 wideband, you need to order them preprogrammed as #1, #2, etc.
I have a 30-2310 and I have found most the info I needed. I believe I have the analog displaying correctly in the scanner but Id like to compare it to serial before I trust it. I have found this thread on accident before realizing what your doing here. Is it possible for you to rewrite this one as well for CAN instead of serial or do change the analog to lambda for better resolution?!
Are you reprogramming with a UART device if so I haven't interfaced one in ages, Just wondering.

So I currently have the AEM single AFR X=Series OBDII passthru version. My question is, is this using CAN bus? Is it possible to run dual AEM AFR gauges and record them separately in HP tuners using CAN Bus? I know this can be done with the analog inputs with the Pro-feature, but CAN BUS is the question. 2nd CAN bus question....... I'm installing a Stratomaster Blaze TC-6 gauge that has a CAN bus output. It's a 3.125" aircraft gauge that can record and display anywhere from 1 to 12 EGT or CHT probes. Is it possible to record 8 EGT temps into HP tuners via the CAN bus? I already installed all the header bungs 4 yrs ago as a safety, but didn't complete it. After a 2018 and 2023 single piston meltdown at the Texas Mile, I'm going forward with it as a safety. The programmed in MAX value can set off a normally closed ground - which I can use to kill my 250 nitrous shot while still pulling the timing and save the engine in the event of one injector (or anything high temp causing) going out. The gauge can be used as a standalone MAX value & alarming system....... but being able to datalog along side of 4 moveable AFR sensors would be priceless for the Mile Runs. If there's a better CAN Bus thread to post this in, let me know. Thanks!
Bump this thread as I'm still looking for options to flash the 30-0310. I reached out to AEM but they are unwilling to do it. If anyone is willing to unload their flashed one I have a new (unflashed) in box for trade.
AEM isn't going to flash a gauge with custom firmware written by somebody who isn't AEM. You need to talk to dr.mike.
is it possible to do the same thing but for EGTs? i am working on tuning my Cummins powered truck and EGTs are important in that process. i run an Edge CTS3 monitor normally, but there is no way to import that data into to HP Tuners. at least that I'm aware of. so when I'm data logging, i have no info from my Edge as it is unplugged. I'm looking to add in an AEM EGT gauge since it appears to have the same data stuff as my AEM wideband that Dr.Mike flashed for HP Tuners to read that for my LS stuff. the gauge I'm looking at is the AEM X-SERIES EGT GAUGE KIT Part #30-0305.
I am currently recovering from yet another eye surgery. This one seems to have better results. I hope to be back up and running by the end of the month.
The 30-0305 outputs the same AEMNet data format as the 30-0300. But, I do not THINK that HPTuners read/interprets the temperature data packets. I have not played with the 30-02224. I ASSUME it uses the same data format. Need to check the instructions, for that.
There is, currently, no OBDII firmware package for the 30-0305. In theory, there could be a patch that performs the same functional changes.
But, the demand does not seem to be out there for it, yet.
And, I have no idea what firmware the 30-2224 uses. I do not think it is based on the X-series platform.
In the meantime, I am handling a bit of a curve-ball. Someone just sent me a CHEAP Chinese knock-off of the AEM 30-0300. You may have seen them, on EBay, Amazon, Or AliExpress. While they LOOK legit. They are absolute garbage, functionally. Slow, inaccurate, and noisy. I will probably do a post on them, later. Or, maybe post my initial findings, now. Just so people know.
It is a bit scary that they reproduced the plastic parts, exactly ( including a couple of mistakes that AEM made ). So, just changing the face-plate to AEM makes them physically indistinguishable, until you turn it on. So, I expect full-on counterfeits to pop up ( if they haven't, already ), on ebay, amazon, et al. Be forewarned.
