Has anyone here ever successfully used TP to read data streams from a 93~95 4.6L Northstar motor? Specifically a 1993? These ECUs seem to require two-way communication between the ECU and the scanning device to get a data stream working so thus far I've only been able to use an expensive Genisys 5 u...

So I made a usb to aldl odb1 cable and would like to use tunerpro to read and burn new chips for my car.

Where can I find the proper definition file (XDF) and diagnostic files (ADS) for my 1993 LT1 Camaro? Is there also anywhere I can find bin files to play with?

from what I remember, the 7429 was able to be used in place of the other ECMs used up until its introduction, it essentially had some hardware fixes and got a new part number because of it. the turning over but not firing is odd... what happens if you plug it in while the engine is already running?...

I'm currently using a 16180517 ECU with BHMU bin on the 93 4.6L. Would a 16197429 ECU work on a 93 with the BHMU code? Everything I attach to the ALDL port including a hand held scanner that is suppose to work seems to short out the data line because every time I have something connected to it the c...

Unfortunately the only guys I've found that have cracked the N* ECU is Westers Garage people. If there is a way to read the ALDL data stream with a laptop I haven't found it yet. I'll be testing a hand held scanner this week to read the data stream.

L and M seem to act as redundant circuits for each other, likely due to how dependant all of the modules in the car are with each other. it does need to be "activated" in that the always being transmitted datastream needs to be disabled via commands from a laptop(or tech1 or xxx), then se...

hmm..... hard to tell what exactly is going on there. anyways, here is what GM did for what looks like all possible options on the 93-95 northstars(except for the allante): http://imgur.com/3MAiMkB,d6wkJMW it would seem that you can have a broken wire anywhere in there and everything will still wor...

do you happen to know the exact year/model of the car your harness was pulled from? the L and M pins are used as kind of a ring network(i believe that's the correct term)... it varies a bit depending on the engine/year/model, even if it is a domestic market vs export car. He used a aftermarket harn...

i don't have a 93-95 northstar car to play with..... i've built prototype definitions and had people test them. any ALDL cable that works with 8192 baud datastreams should work. i looked into the connector issue, the B pin only appears to be used on the 4.9 cars to force it into set-timing mode. gr...

with a northstar PCM, you should only need A and M.... i'm not aware of the B pin even being populated on them. So how have you hooked up to this to get ALDL data in tunerpro? What cable etc did you use? Should be as simple as hooking to M for data and A for ground and turning on the ignition to st...

i'll gladly send them under the warning that they're very incomplete and only useful for a 95 calibration. Oh ok, ya they won't work for me then with a 93 calibration. Question, I made my own ALDL cable from the link below and hook the green and white wires to the "M pin" (Tan) on the ALD...

https://www.dropbox.com/s/8iv6n45gpcrzhyf/A210%20test.adx?dl=0 try that ADX, it isn't what i would call finished(reorganization and labeling needs done), but it should work well enough to see if things are going to play well together. any ALDL cable that works with other GM stuff that operates at 8...

tunerpro will do it, as long as you have an ADX that will work with it. i've built at least one for the northstar applications, but have no way of testing it. I used the northstar.ADS on the website and converted it to a ADX in Tunerpro. As far as cables to use will the normal USB to ALDL cables fl...

Westers definitely has access to some stuff, couldn't say how much. i've poured through my own disassembly for many, many hours and while i've likely found all of the tables in both sides and given them rough labels, i've only put definitive labels on maybe 5-10% of them since the rest are rather u...

http://northstar.7p.com/ that is one 7730 route, though it is setup for a 5 speed fiero. i'm not necessarily a fan of where the calibration ended up at, but it can/does work. i don't know about the 96-99 northstar PCM.... i know it is a somewhat related version of the 93-95 version in that it still...

it will need to be present for the second processor to function. without it, the primary processor won't be too happy when it doesn't receive any communications from the secondary. however..... that is a large jump in operation to go from a 4T80 to a 700R4.... the transmission side isn't going to b...

the northstar PCM is one of 3(i think) series of dual-processor PCMs, the other two are the 94-95(and slightly modified 96-97) LT1 and the 93-95 3100/3.4RWD PCMs. having two processors, they also have two PROMs. generally, everything is split more or less into an engine side and a transmission side...

I was able to get the superseded stock bin file for BCRL which is BHMU and the BHMU trans bin (second chip). I'm new to this second chip thing, can you tell me what the heck the second chip is for?? I'd really like to be able to mod the files but the no XDF issue again. :( PM me if you get a chance ...

i'm showing BCRL as being the E-body(eldorado), HO Northstar calibration. i don't have that exact one, but i do have a BBSX, which is superceded by BHMU. BCRL is also superceded by BHMU, so there is a good chance it will at least be close to what you need. Hi! thanks for the reply. That could work!...

Looking for a bin and any other definition files etc to use TP with a 93 4.6L Northstar motor ECU 16183556 (service# 16180517) BCRL on the box but someone installed an aftermarket chip with the wrong broadcast code. (for a totally different motor)
