It's not super clear why this happens. I have a firmware patch for the 30-0334 that seems to solve the issue. for those who jave tried it. But, it is, technically, a violation of the OBDII stanfard.
Yes. A common problem when trying to set up the analog inputs into the scanner is the Analog- wire not being connected to the scanner ground. When it is not, the output voltage will be wrong. And,...
Did you run the Analog- line to a ground pin on the V2 scanner ? Not having a goof ground on the Analog- pin of the gauge is the #1 cause of analog issues with the x-series widebands.
Yes. The gauge is the part that needs the re-flash.
The gauges are not matched to the sensors. Each sensor comes with its own calibration. I was just thinking that having 2 gauges, 2 power...
Wouldn't you still need the sensor cable/harness ?
They will have to send the gauge in to me for re-flash. There is no good way to do it, in the field.
PM for shipping info, if needed.

I have a re-flash mod for the 30-0334 that has fixed some freeze issues w/ V8.
The analog output from the 30-0334 is preferred over the serial. In either case, you would need to add the associated pins to the connector.
The serial output of the 30-0334, as shipped, is...

Are the keep-alive messages logged ? The ones to 0x0101
If one is not received at least every 5 seconds, the stream will timeout. If they are sent exactly every 5 seconds, there may be a race...
IIRC, The 30-0333 does not support EFILive. Just "Brand H". The 30-0334 was designed to work with EFILive in both single and dual configurations.
I wouldn't worry, too much, about the Seebeck effect, in this application. Plus, you will have the law of intermediate metals on your side :)
So, I am a BIT biased, in favor of the CAN/OBDII method of wideband connection, where possible :)
But, the 30-0300 analog output is VERY good.
The 30-0300 analog output is fast AND, it has active ground offset compensation ( The LC-2 is "single-ended" ). So, it is MUCH preferred over the serial output. Which is, as mentioned, only 10Hz and...
Keeping the power cable runs short is generally a good idea. But, the newer AEM devices do not suffer the same ill effects of power rail fluctuations as the LC-1. Same, technically, goes for the...
Yes. The 30-0300 makes the most sense, in that case. Or, the 30-0310, if you don't want the gauge. In either case, you get the fast response time, and, the corrected analog 0-5v signal.
almost:
30-0300 is the original part. Its CANBus interface is used for AEMNet communication. It has wires on the harness for 0-5v and serial data. It has CAN wires. But they are NOT programmed...
The 30-0300 is the one with all of the non-CAN functions available on the wiring harness. The old 30-0333 is the same as the 30-0334, but without the updates for EFILive. (i.e. mostly, for "brand H"...
IIRC the 411 PCM is J1850 protocol, not CAN protocol. So, the direct OBDII interface connection will not work; unless the scanner can read 2 different protocols at once. Maybe this is possible ? ...
Mostly the response speed. So that the WB data matches the RPM/MAP data. But, that only really applies if you use the analog or CAN data. The serial on the x-series defaults to 10Hz.
The serial...
Hi All.
AEM has finally introduced the new 30-0334 version of their OBDII enabled wideband ( Formerly, the 30-0333 ) that supports single and dual widebands in FlashScan V2. This is based on...
Pretty sure it will work. I think they only say 2008+ because it is guaranteed to be CAN.
Yes. That extra bit of functionality is responsible for the delay in getting EFILive support up and running. The dual-wideband code came right at the end of the qualification of the original 30-0334...
Good news. AEM has finally released the 30-0334 replacement for the 30-0333. This is the equivalent to the most recent re-FLASHed units that I have been doing. They support dual widebands with...
