Who makes the 24V coding plugs?

[nando]

I can see how this works for MS better than nothing, but the rate of consumption is dynamic to atmosphere, driving conditions air temp etc. I always understood the OBC having gathered and calculated all relavent data and produces a constantly dynamic MPG AVG,range and avg MPH, etc. The OBC gets this info from the cluster with exception to outside temp, anyone who has ever retrofitted a 16 button knows this. If you put in a static adjustment your range won't recalculate the approximate distance to empty, It would read a set calculation of how much gas is in the tank / the sum of the equation your board dumps out.

What? no it's not. The only thing that matters is injector pulsewidth, and the size of the injector. Fuel flow is linear with respect to pulsewidth. Since you know exactly how much fuel mass flows through an injector at a given puslewidth, MPG is basically pulsewidth/MPH. Air density and other bullshit doesn't make any difference. You don't have a clue what you're talking about.

the only thing the coding plug tells the OBC is cylinder count and injector size. the reason your OBC/econometer goes to hell with a swap (or standalone) is because you've changed injector size. nothing else makes any difference.

Therefore your 3 gallons of gas you have will get you further than what the OBC says because your economy is optimal at speed, or vice versa if you are stop light to light. Or you set it in the middle and deal with the, meh it's close enough.

Wrong. All that matters is the mass of fuel you used (known because of linear injector flow rates) and the distance you've traveled.

Needs more dev , I'm done with this bullshit. Free muthafuckin planet I can give this guy solid feedback and he can handle it without all the little cheerleader bitches. For me, it can be off now, it doesn't seem like throwing dough is going to get my OBC any closer and I just have more splices in my car. Fuck it.

it's quite clear you don't have a clue. it's actually hilarious to listen to you bitch when you don't even understand the basics of how instantaneous MPG works..

Sooooo....how about that group buy?

I'm interested, just not sure if I need the standalone or standard. OBDII S52

Even if I could do it through the coding plug, it still wouldn't work that well. Your injected fuel is based on your injector flow rate from their size and your specific fuel pressure. Are they dirty or clean? Is your FPR calibrated to exactly 3.5bar?

My board has adjustability so you can calibrate it to match your EXACT fuel consumption. No coding plug would consistently get you to +/- .2 MPG.

So if you are running MSII with wasted spark, will this still work since you have 3 seperate coils?

Coils don't matter, all you need is an injector signal. I had mine wired directly to your ms board, the input hooked to the INJ1 header and the output to the regular fuel rate output pin.

No E36 uses a coding plug, what you're asking for does not exist

Go pull a cluster off any 92-95 e36 on the back is a white coding plug in the back, on the OBD2 clusters there is a provision in the mold but the access plug is tabbed an no socket.. How can what I'm asking for not exist if that's the way BMW handle this issue with engine configs?


I buy blueberries too, but I wouldn't pay $6 for a pack of them out, I'd go get a can for $.99. Smart peeps don't buy out of season Mexican fruit.

The point of this thread was to find out who the COMPANY is that makes the coding plug fix. I know I saw a banner on the bottom of R3V about 3 months ago and it had a .gif with an OBC flashing dashes on the display for this.

Hoveringuy don't let me get you down I doubt you are. I feel like you could dish out a little better product and merit the price you are asking.

Good product idea, good member to the community. I just hope you aren't trying to make over 50% profit on these $16 of Taiwan chip and PCB.

Huh? The coding plug tells the cluster what motor the car has in it. The cluster feeds that info to the obc. It takes the gauge level and calculates it into range etc. What I am talking about is a modified coding plug that is programmed with the correct algorithm for the 3.2L 24V. Slips right into the orig code plug casing or has a plug with ribbon cable what ev. Most clusters in BMW's have coding plugs in them. I am curious about just snatching one from a 95 M3 cluster since OBD2 stopped doing coding plugs and this would be the closest parameters to my engine. On my Z3 I had to swap clusters to correct the tach and the OBC corrected itself..... and it's days of displaying avg mpg 32 were gone.

You have shown, on many levels, that you have no idea what you're talking about. The coding plug deals with tach operation. That is, number of cylinders and tach scale. It has nothing to do with the displacement of the engine, which means jack shit when calculating instantaneous gas mileage (for reference, that would be the injector size and duty cycle, as well as base fuel pressure).

I am not going to go into your ridiculous pricing expectations except to say that when you have done the work yourself on a single similar product, then you can speak. You have brought great shame to your famiry.

I think the public needs to here this.

Way to go bro...

Here's the E30's diagram.

I went to the grocery store yesterday and a pint of blueberries was $6.00. Everyone knows you can pick those yourself for FREE!

I love this, will use it.

Steve's board gets spliced in the circuit below (or one similar depending on your application) The DME is the dotted box at the bottom.


E30s use a coding plug in the OBC and the cluster, if you pull up the ETM for say, an 87, on page 6210-5 it shows the layout of the fuel rate circuit.

It goes to the cluster on pin 11 where it is spliced directly (unmodified by the cluster coding plug) to the OBC output, pin 25, where it's up to the OBC's code plug to correct the signal depending on engine configuration.
