Porken's modified EPROM - EZK - S
Posted: Sat Jun 06, 2026 11:34 am
I posted this on the other 928 Forum about my experience with Ken's EZK modified chip (there are nearly 300 posts about it there). He developed this 'learning' chip about 3 years ago. Link: https://rennlist.com/forums/928-forum/1 ... -chip.html

It's been quite a while since anyone has commented on Porken's EZK - S product, and I recently had mine installed (automatic GTS). It was done by Rich A., as he was also refreshing my LH unit. I've now driven the car about 70 miles since the refreshed LH and the EZK-S were installed. I'm VERY HAPPY with the results. I've done the recommended 5K+ to below 2K and 4K+ to below 2K runs for the chip to 'learn'. The car just seems to have more torque at low/mid range, and a noticeable transition in acceleration torque when crossing 4K on full throttle. The engine and auto trans just seem perfectly mated for either gentle driving or for aggressive driving on our twisting roads. At idle of 625 rpm (per tach), the engine is very quiet, and absolutely no vibration if trans is in neutral or park.
I'll echo a previous poster about the EZK - S EPROM, as it's true for me as well:: "Best Money I ever spent on this car"
Thank you Ken - job well done.:
