Still here. We get new members all the time. Not much forum chat though. It has always gone in spurts. Recently, George and I have been working on the MAF...
Hi Alexis. Yes – it is a 8052 based system. The tables are not the problem. I do have a somehow a kind of understanding of the code. Idle speed is balanced...
In M3.1 or ML4.1 There is a table with RPM (eng T) and another table for the idle valve position, probably for the initial value used by the PI controller. The...
Alexis: I have several 944S BIN's in the file section of the forum. I too am very interested in all the maps. I have a MCS chip emulator so I can easily tune...
It is documented in our files section how to calculate the AFM flow for a given signal: for(i=0; i < 256; i++) { unsigned b7_5 = i >> 5; unsigned b4_0 = i &...
There is no math. I just translated the 8051 assembler code into a C code. There is certainly a function which links flap position to the air flow in the...
MAF would be in kg/h. There is a Bosch component catalog that you can find on the web, it contains a few curves for MAF. Unfortunately the graph is very small...
... Yes. With the density (kg/m3) of the air you get the volume. I do have the curves I need. I developed some AFM to MAF conversions for some cars with the...

George and I have been working on the VAF to MAF conversion for a while. We are using a map for this. I put both the factory Porsche 944S VAF and a 2001...

Just to visualise my phantasies, I added a screen dump to the file section.The green line was the self-measured AFM-curve, the red one the result of the AFM...
Very much agreed! That was my goal as well. We were progressing in steps. ... From: T_Voigt To: BoschDME@yahoogroups.com Sent: Wednesday, June 25, 2008 7:21...
I just got some examples of the DS89C450 in my hands. These 8051/52 clones are impressivly fast. Around 10 times faster than a standard 8051 at the same clock...

The schematic is similar to the ones in the file section, but they are not the same. Jim and I traced some routes with a meter and we could not find a ...
Mine is a 944S so it is different than regular 944 and different from 951 (944 turbo) also. ... From: George To: BoschDME@yahoogroups.com Sent: Sunday, July...
