info about the processor chip in your ez68

https://pdf1.alldatasheet.com/datasheet-pdf/view/66066/INTEL/8751H.html

The 8751H is an EPROM version of the 8051AH.
It has 4 Kbytes of electrically programmable ROM which can be erased with ultraviolet light.
Is fully compatible with the 8051AH but incorporates one additional feature: a program Memory Security bit that can be used to protect the EPROM against unauthorized readout.
The 8751H-8 is identical to the 8751H but only operates up to 8 MHz.

Fourth revision has been approved and sent to fabrication.

Thx

Thank you. I know nothing about the factory part. I do remember this engine project when I worked at Andial. However, those units were delivered from Germany and we had nothing to do with their inception.

Any time you add aftermarket parts you run into plug and wiring issues. In this case we had no other way. It solved a problem and worked well. The customer was happy as his car sat for over 1 year while a solution was found. We solved the problem in days and he was very grateful.

Remember anyone saying "math might save your life" ?

I guarantee it wasn't an engineer.

defining accurate pin placement for the connectors involves this :-

What has happened here, http://forums.pelicanparts.com/911-930-turbo-super-charging-forum/820323-digital-wur-plus-frankencis.html lately?

FrankenCIS is still going strong out there in the real world, not much activity on the Pelican thread though.

What we are doing for the Mercedes folks with the EZL, will pretty much become the new version for them.
No Microsquirt and direct control (optionally) for the KE-Jetronic on top of the EZL ignition.

What's the link to the product description and availability?

Surely, you'll be adding knock-control thru the multi-connector, right?

The EZL is still under development, but the primary requirements in order of importance are :-

1. Plug and play - no wiring changes
2. Looks OEM
3. Ignition tuning

As a 965 owner, I so excited to see what you come up with. I just used my last spare

Please PM once you have working' unit available.

Many people on Reenlist 964 turbo owners that use these units are mostly on that site. It would be good for the 965 Ez69 owners to see what you have developed. You will have great success there.

Please start a thread there. You will have plenty of customers there.

Shall do,

The Hardware is running on the bench and the firmware core is functionally complete.

The design and implementation is closely following OEM features and requirements with a few modern tweaks to enhance reliability and protection.

Case and connectors are not yet finalised. As we back-and-forth with suppliers, specs have been refined to match manufacturing realities.
So we are frequently deciding on little details, and then rinse-repeat.

Also, everyone, please hang on to your dead ones as we might also be able to do an exchange program for the EZ69 case.

The schedule has us well placed for in-house vehicle testing of two different prototypes by early April, so maybe mid-year for one or more hand-built units to escape the lab.



poor little naked one on my desk now :)

Thank you for the update. This is so exciting. We appreciate you hard work! Are you going to start a thread on the Pelican 911 turbo and Reenlist 964 Turbo forum?

Thanks,

As for a dedicated thread, here or elsewhere, I want to make sure we actually have a viable solution first.

Hi, I hope you had a few productive few weeks, any updates?

Hi,

Nothing definitive, physical aspects of case and connectors are the current focus.
As expected, bespoke parts are required for 95% of the module.

Still on track for physical on engine beta testing mid to late April (Mercedes)

WOW. I had no idea this was happening. Holding onto spare cases for sure.

You might also be able to use MBZ cases from dead units as they are so plentiful. Perhaps there are differences on the vac hose sensor though, maybe that's also being replaced...

GENIUS WORK pls carry on!

the crazy continues...

CNC finished upper housing from a formed blank of PA12-F nylon allows the 3d features such as the manifold pressure port and programming connector, the CNC steps then work with the required 0.5mm wall thicknesses between the main connector pin voids and keyways.
