Re: New owner checking in
ok submarine...I just got back form the woods and can respond w/o hit and miss (my laptop died sat just as I was loading the RV)
Ok, first, lets talk about the car. LOVE IT.
circumstances changed and I was able to drive the car from here to home and back (its complicated) and I threw 600 miles on it plus since purchase.
The dipstick is down perhaps1/6th qt. since I dont know how many miles were on it when I got it since oil change (OLM said 88%) its safe to assume I dont have the oil-suck problem at this time.
Next, the multi zone climate control...it appears the rotary in the upper left controls the base temp for the car, and the passenger and the rear occupants simply modify higher or lower from that? (it does not appear to be like our 2016 RAV where her dial says one thing, mine says another...)
Next, the radio is not bose - at least it does not have the word bose anywhere. pressing a few buttons it cycled thru FM1, FM2, AM, XM1 XM2.
aha. so its built in XM, now I have a starmate with forever subscription so Im still swapping the radio, but my hope is that the antenna on the roof I assumed for the OnS is plug compatible with the XM plug? anyone ever have one of these out? Im assuming the antenna is S-band capable?
LAstly (for now) the shoulder belt retractor, is supposed to be raised/lowered - how? the seat back tilt button does not go up or down on either front seat. how to trigger any movement?
now back to the ecm stuff...like I said if anyone is serious, start a new thread or send me the stuff via my registration email. If these 'tuners' - whom I do not know nor ever talked to, are just uploading tables to a system without knowing what is being done, well, with all due respect, that's just flying blind. I *really really really* need to see the source code. relax, it is absolutely not encrypted on those years. (I proved this over the weekend by poking thru the tables with a scan tool made in 1996. IT would not know encryption if you dropped it on it.
why do I need the source code? well what if gm reads a number from a table that determines spark timing. what if the number gm programmed and certified with was ALWAYS 1-9. What if the tuner added a 10? what if the software reads the number and does a validity check cuz the gm programmers have the ability to know what THEIR values were.
So to make it simple, this is not OBD1, or 1.5. Without the code, you will not be successful, you will only be lucky. I am not going to take apart my car. I am not going to buy another ECM and read it. USe a COTS reader and download the program from that ecm you have and send it to me and I can try and dis-assemble it. Most likely send to a pal who spends every day programming seimens PLCs for raytheon (yes, sometimes we launch them at enemy aircraft)
You inadvertently answered a few questions for me in your last post - re the VIN. remember I wanted to know if the ECM was VIN aware, that means it probably (I am guessing here, but these are ways it will be done - trust me) the SPID is uploaded during build and there are real time modifications to the OS based on values found OR the first few (up to 10) digits of the VIN are used at during assembly/compile time to generate personalized software for that car to be loaded at flash time.
Since this started with the speed limiter, this is referenced in one place only - to shut off the injectors when exceeded. It used to be a byte (FF = 255 = really friggin fast) it may not even be present in this ECM, if what the other poster said was true, that those 3 5 digit VIN prefixes referenced the model, and if those models came with S, T, H etc tires in order, then the speed value can be set at start up by reading the vin, or referenced from the SPID if in fact there is an RPO for the tire speed (was there in that year? I dont know and am not going to look)
At any rate, get me what I asked for and I will lend a hand.
but let me ask this, the 1999 that does work, does it have the same sensors? (I dont know and Im not going to look) if so, you have your blueprint, if you cannot alter the program in the 2000 because you have no listing, there is no rule that says you cannot REPLACE that program with your own. Any tech2 user can do that. In fact, I check recalls and lowly gm techs replaced data and software a number of times for recalls during the referenced years (2000-2004), replace it with the 1999 and add the data you want. Since the MOU for R2R is still in effect and you can download the tables from GM and use the tool of your choice, we know its a simple matter.
and lastly, everyone and their brother are making EFI systems now. You dont have to use a GM ECM. You DO have to conform to the tier/bin emission the car was certified with. if you get another ecm and load in a program you think works - go for it. But I want to touch on this, I have not heard the whole story and dont know why all attempts are marked as fails, failed in what way? The ecm has one and only one way to know that it did not properly control emissions - the compared values of the upstream and downstream O2S's. And nothing else. No tailpipe sniffers, no magic fairys, no beams from space. if you set a trouble code which required the ecm to go into a self defensive mode...well, you are back to doing what I said to do above...replace the program with yours.
So there ya have it, start a new thread and get me the data and background I need. We will go from there.
