Digifant 1: read live data over serial k-line

        digifant 1 live data

My custom extension to read data out of the digifant 1 via serial k-line runs rock solid since 2011. I removed the oem code for fault diagnosis (blink code) and implemented my own protocol to write data to the serial k-line with up to 64k baud. I reach a much higher data rate (output of 32 values up to 100Hz!) as the kwp 1281 group readings from early 90ies. I’m using this to monitor important variables like knock detection while remapping the ecu. Main article: read more

LaunchControl and WOT-Shitfting for Digifant 1 Ecu

webcontact@gummel-informatics.de (Dominik Gummel) — Wed, 07 Nov 2012 00:00:00 +0000

I developed a LaunchControl addon for the Digifant 1 firmware. My LaunchControl cuts the ignition and builds up boost while the car stands still (like the well known WOT-Box oder some free programmable ecus like KMS). For example it’s possible to build up 1.5 bar boost (21 psi) standing at the starting line of the dragstrip (drag slicks are advisable for fwd cars like the corrado). WOT-Shifting is also available: cutting ignition allows to stay on WOT (wide open throttle) and keep the boost while changing the gear. More information

Digifant 1 Ecu with 400kpa map sensor

webcontact@gummel-informatics.de (Dominik Gummel) — Sun, 01 Apr 2012 00:00:00 +0000

I’m able to do Digifant 1 remappings using a 400kpa map sensor. This allows to use the Digifant 1 with 3 bars of boost (44psi)!

Digi-Lag defeated

webcontact@gummel-informatics.de (Dominik Gummel) — Fri, 01 Jul 2011 00:00:00 +0000

VW implemented a delayed reaction on WOT (wide open throttle) which stays in closed loop mode (Lambda 1) for ~ 3 seconds. This causes suboptimal performance on the transition from idle / part time throttle to wot. I eleminated the Digi-Lag in the program code. read more: delayed WOT enrichment a.k.a. Digi-Lag
