AEM 30-0300 Wideband with direct CAN integration W/ VCMScanner. Need beta testers.

[dru21281]

Wideband is ordered!

Just tried to order a 30-0333 and they are on back-order which sucks, expected 2-3 weeks...
If I get the inline 30-0310 or 0300 will either work on HPT if I hook up the 2 CAN bus wires through ODBII or is the 30-0333 the only one that doesnt need the firmware update?

[dr.mike]

The 30-0333 is the one with the OBDII firmware. The others need re-flashing.

Thanks dr.mike! Just sent you a PM.
If anyone has a 30-0333 for sale or knows where I get one by next week please let me know . Sorry to derale the thread

[schpenxel]

I think I got the last one that place on amazon had

Dr Mike look what you started. Tonight I let my kid hold the NGK in the bonfire to get an AFR reading that's how much i like it still. But it was so slow the wires melted before I could get an AFR reading. It was either that or his thumb kept hitting the dial a knob on the back that I never really understood.

[dr.mike]

There is nothing "wrong" with the NGK AFX Powerdex; as long as you understand what its limitations are.
As widebands go, it is one of the better made units.

a knob on the back that I never really understood.

You never used the calibration knob ? Or, is that something else ?

theres only one knob.

first time reading this thread... only 2008 and newer cars?

[dr.mike]

It can be used on pre-2008 cars w/ HPTuners 3. But, it requires the installation of an extra resistor in the wiring, to provide termination, since there is no CAN ECU to provide it.

[schpenxel]

What resistance do I need? And how do I connect it? Just connect it in parallel with the two CAN bus wires?

[schpenxel]

The AEM is back ordered 2 weeks now--just got a message from the person on Amazon that had them for ~$200. So, going to be a little bit before I get mine. AEM is out of stock and making more. Guess they're selling.

[Stuffs]

so for what understand the wb readings will show up in the scanner as is rpm , temp and all info delivered by the PCM , no more cables using the IO input in my MPVI PRO

sorry for being a prick lol , can someone wrap-up the advantages pf the 0333 from the 0300 unit please? i dont have too much knowledge in CAN buses and protocols

[schpenxel]

0300 will not show up in HPT without dr.mike reflashjng the unit to work with his custom firmware. It's designed to work with some kind of aem logger box.

0333 will show up in HPT when connected to obd port. No wires to mpvi pro 5v inputs required

[dr.mike]

Properly, you need a 60ohm resistor. But, anything from about 56ohm to 68ohm should work just fine. ( 56ohm and 68ohm are MUCH easier to find than 60ohm )
Probably, the 68ohm is preferred. Use a 1/2watt size. They may be available at RadioShack ( if they still exist )

This resistor is wired up between the CANH and CANL wires. It is already present on ECUs that have CAN communications. So, it is not needed on the later ECUs.

I have not seen the 30-0333 cables. So, I don't know the easiest way to do it. But, I assume it would be near the connector that plugs into the gauge.

The pins are probably ( almost certainly ) not present on the vehicle's OBDII port.

[schpenxel]

Two 120 ohm resistors in series is another option--120 seems to be a bit (lot) more common than 60

I'll give it a shot whenever mine gets here

[Stuffs]

so now anyone buying the 0333 and not interested in stand alone logs can save $$ and go for the standard mpvi and get almost the same benefits of the wb integration as the pro version does?

[schpenxel]

Yes. The exception being you can't connect any other external sensors if you ever need them. For WB only the standard interface + 0333 will work.

[Stuffs]

1st time i feel like my pro is pointless , i wish ive saved that money difference for a wb

[dr.mike]

On the standard bus, there are two 120ohm resistors in parallel, at opposite ends of the bus. The two parallel resistors work out to 60ohms, equivalent.
Since there is only one "end" to the bus with only on node ( the 30-0333 ), its easier to just use a single 60ohm.

With such a short run, it would probably work either way. I have run short CAN busses with just a single 120ohm resistor; and, not had any troubles.
