| 1227165 ecu with custom code much better than stock ecu. (Page 15/26) |

Cool.
Make sure you get a memcal from a v6 7730 ecu and have a 512K EEPROM burned with your code. This is a backup in case the NVRAM gets corrupted. The test car that is in Missouri got water in the ecu and shorted a connection, corrupting the NVRAM. Luckily I had an extra memcal and flash chip that I could burn and send to the owner. So far working good, it just does not have the flash tuning and self learn abilities.

I have an ostrich as a back up. Going to get some logs for you to look at soon. How are the other projects going?

Slow, especially with paving season. 14 Hr days for most of the week takes it out of you, being in all the weather and the heat/fumes from the road material. Now that paving season is over, hopefully I will have more time to work on the many projects. I am close to having the trip computer finished. I just need to finalize a circuit design and get a couple made. [This message has been edited by chetw77cruiser (edited 09-22-2012).]

Since Four_hundred_86 will not bring my car back, I had to go purchase another car.  Turns out that it is also an 86 SE v6 like the last one, only better. So now that I have another V6 car to work with, I will be getting back to working with the 1227165 ecu swap and get things dialed in better. Along with this I also plan on installing one of the first trip computer/digital instrument clusters into the car and use it as a test bed, so keep your eyes and ears open.
Feels good having a car that isn't needing much work and can be used.
Keep tuning my friends.

This is what I need for my 86 GT. Anything that improves the MPG's is a plus.

What cpu does the 7165 use? If it was only used between 86-89, I doubt it's as fast as the one in the 7730. The language may be compatible and you may be able to adapt the code into a custom '7730 build.
Just curious. They should all use the same family of processors. The Fiero ECM uses a 1Mhz 6800 and the '7730 uses a 4Mhz 6810, I believe.

Ah yes, I think it and the '7730 use the same cpu. 4Mhz. Now it's a question of RAM... I guess my point is that the code can easily be ported to run on a '7730 if a 7165 is hard to find...

The processor may be similar, but the hardware and porting is different. There already is a NVSRAM board for the 7730 but it is only ported for a modified version of $8D code. The board is available in kit and assembled form from moates.net. The $8D code has a fairly steep learning curve, but once mastered, I believe it is the best code for use in the 7730 in non-boosted applications. It is even compatible with the Fiero EGR system. No adapters needed for a digital EGR module.
Oh, the 7165 was also used in the S series pickup with the 2.5 Duke engine prior to the switch to the 2.2. Availability should not be a problem.[This message has been edited by chetw77cruiser (edited 02-01-2013).]

Right but remapping ports is no biggie. I guess the big difference then is that the 7165 has non-volatile RAM where as the '7730 doesn't.
They probably both use the same processor at the same speed. I was wondering because I'm already using a '7730 in one of my cars and I hate downgrades.
