I've been wondering something about the extended maps. Because they store to L0054 instead of L0057, does that mean it doesn't do air temperature or barometric...
For anyone who is interested, I have been digging into the basic operation of the ECU electronics (1G). I have a partial pinout of the MH6111, a full pinout...
Hi Doe's anyone have installed the GM 3'' MAF on a 1G without the translator, but doing the mods on the chip on MAF compensation ???? The car have a GT30R with...
Correct me if I'm wrong, but you still have to translate the hotwire signal to the karman signal and hence the need for the translator. The ecu doesn't know...
Since my commute to work from my new house is 100mi round trip per day, I've been searching for better fuel mileage. Reading that Bill is able to use a full...
There was a thread on this last year, did anyone have any luck? ... From: "Robert Honea" <rhon@...> To: <dsm-ecu@yahoogroups.com> Sent: Monday, February...
I guess it depends on what your using for a maf. A GM maf locks airtemp and baro down anyway, so you wouldn't get any correction from their changes. Since it's...
I finally benchmarked one injector last weekend using a custom ECU program running on my car. The program just runs a given number of injection cycles with...
I think I remember seeing 1.5ms using MMCD but the value reported is truncated big time so it is difficult to say how low it really went (between 1.5 and...
I work as a GM tech and we have displacement on demand in new v8 vehicles. Thing is, its more than cutting spark and such. According to the training, it...
Christian, Have you thought about running the same test with a stock 450cc injector? Your results don't seem to correlate well to the ECU deadtime values. I...
Yes, that would have been a good idea, if only I thought about it before running out of time and putting my car back together (this is my daily driver). In my...
Drew, Actually, the answer to that question is: it depends. ;) If you look at the code at D57E, the 16-bit airflow is loaded to D, divided by 4 (which ends up...
Yeah, that's where the Miller Cycle would be nice and effective. We have the capability to retard the intake cam quite a bit but that still might not be enough...
the few mafs ive tested all put out a frequency like our mass, but it is a much higher hz output. the maf itself already compensates airt and baro, and the...
There is no such thing as "karmen signal" Sensors output either voltage or frequency. The GM sensor and the DSM sensor both output frequency so that part is...
The biggest problem we ran into is that the output is exponential. If you look in the Files section under 'Projects / Hotwire MAS' you can see some work that...
Did you also considere the added load on the ECU. By my calculations, each pulse received by the ECU consumes about 180 cycles. At high Hz, the ECU already...
Hi Guys, I am on a mission to create the one definition file that I need for tunerpro and cannot seem to get my hands on. The 4 Cylinder 2 Ltr VR-4 Definition....
After going through Christian's disassembly I came upon something that has been missing from our 2G MAS conversion. No one ever mentioned changing the air temp...
This is something i have wondered about too, as since i changed to a 2G mas i have seen different intake temps. Might have to do some back to back tests with...
Christian's notes seem to say that this includes a baro compensation too. These are his exact notes: ; This table is an airflow sensor compensation table (for...
Who are you guys using for a supplier for your EEPROMs? I was just placing an order for some other stuff and was going to get a few 29c256's, but found that...

I was aware that the PLCC32 could be adapted with a few wires and discretes for programming in a common DIP socket but, I wasn't aware that the same adapter...
