I have the "regular" EBL Flash and it definitely requires a separate "phone" cable to flash.

Mybad, I think you're right, but I imagine you could repin the serial cable to the aldl.

So your ECM isn't actually getting a wideband signal, right? You're using a WBO2 controller to simulate a narrowband signal. So I'm assuming the ECM itself can't read a wideband (i.e. 0-5V) signal?

In regard to being able to flash tune the ecu through the aldl, the 7165 was never designed to do such a thing. What enables it to flash tune is two parts. One is that the EPROM is replaced with a form of non-volatile ram chip. Two is through the use of a highly modified code that allows the nvram to be written to as well as read from. The processor is capable of this if it is programmed correctly.

I can get a signal from a wideband sensor and it does use that information for many functions. I just have the controller feeding the ecu both wideband and narraowband signals at the same time. My controller allows for that. So the ecu can read a wideband signal. This is not necessary, but what the hey. If you wanted to you could have a WBO2 snesor and a NBO2 sensor also installed into another O2 sensor bung in the exhaust. Could be used as a way to doublecheck that either is working correctly.

OK, thanks for clearing that up. In that case, I am definitely interested in this ECM setup. I have lots of questions. Should I send you a PM, or can I post them here?

Go ahead and post them here. Remember from school what the teachers said: Ask the question anyway, because someone else probably has the same question and is to shy to ask. I was usually the shy one.

Basically the same thing. I like the 7165 because it fits in the 7170 tray and uses the same ecm plugs. More of a plug and play operation. I will check to see if the code I use is compatible with this nvram board. What I am making is a little bit cheaper but requires the memcal to be modified.
If anyone wants to try this nvram with the modified 8D code, I have a base tune from my 86 GT with 4 speed. Transfer most of the parameters to the nvram code and thisng should work.

far cheaper than that other one mentioned. All someone needs to do is edit the codemask for the V6 to do the ALDL changes.
Heck I think if someone talked to the guy he might give someone all the info they need to change the typical v6 Codemask to use this device. |

So far within a little over a week of tuning, I have the engine running much better than the stock ecu ever did. The engine pulls better and longer than it did before. Several times I have hit the rev limiter(5500) in no time whereas the stock ecu would strugle to get there. Did I mention that this code has a soft rev limiter that is fully configurable. If anyone wants to take a peek at the code, PM me for information. I should have a few pictures here shortly if I could just find my camera.

Here are some pics.
The first two are of the victim. Nevermind the missing decklid, it is in the garage curing after a fresh painting.
As one can see, the ecu is installed in the stock location in the stock ecm tray. I have the autoprom running the show right now while I am changing code quite frequently.
Just to show that the wideband is functional. I have a different WBO2 controller that will be installed in the ecu case and will use the stock connectors, just need to run a few extra wires. I do have this computer running the cooling fan by the way.
Just for the doubters out there. Your average 2.8 V6 stock, no mods with a 4 speed muncie.
