I'm not at home at the moment, but I know your car isn't a N-body, fairly certain it is a H. Not sure if I've built a definition for it yet or not.

the PL2303 doesn't work at 8192 baud, which can certainly cause your issues. the only USB to UART bridges I've used that work reliably have been FT232 units, though I have a CP2102(I think?) converter laying around here that I've never tested.

the 6E ADX is very similar to the one that would be correct for your car, there are only a few status bits that are different(going off of memory).

that should do it.

the fact that it's setting code 45 even with a new sensor is odd. I have a pretty good idea of why though. the way the MPFI 60V6 masks calculate idle fueling takes MAP, baro, TPS and IAC into account to make a pseudo alpha-n or MAF value. if any of those values are less than optimal, you get strange...

are you changing all 3 tables or scalars by the same amount?

increase the value for a richer mixture. be aware that fairly small changes here can produce significant results. I believe the resolution is 4mV, I would recommend changing those values in no more than 8mV steps between testings. also be aware that there may be scalars used specifically for idle th...

changing the stoichiometric AFR value will change the fueling amount, but when the O2 sensor comes online, the fuel will be trimmed back to whatever value is determined to be relevant by the O2 sensor rich/lean/mean tables. shifting those values around will change the actual AFR while the ECM is in ...

there may have been more/better definitions released since 2014, but I'm not nearly as up to date on EE than some people on gearhead-efi.

that will be found as P66 V6.adx

yes, I'm just stating that it's a built-in function of the software itself.

Thanks, Robert!, The cars have series 1 engines, so now I should be able to see what is triggering the "Check Engine" lamp. Now all I need to do is make up a proper interface cable, I have some Cisco router/switch console cables W/genuine FTDI FT-232rl chips in them, they are USB to RJ-45...

A221 is accurate if you have a Series I 3800(95 had both series I and series II engines in the H-cars). the BMYU MEMCALs should be for series I engines though. I uploaded this a couple months ago, I don't think I received any feedback about it though. https://www.dropbox.com/s/ywfpagorua8qpwb/A221.a...

XDF or ADX? I'm certain I still have the XDF kicking around, not sure about the ADX.

for just datalogging, you won't need a BIN or XDF, just an ADX file.

i'm not seeing codes 98 or 99 as being valid for your application... digging a little deeper, your truck should be using A217 or A218, depending on which streams you want access to, codes 98 and 99 don't exist in the stream either. I think you've grabbed the wrong ADX. here is a combo of A217 and A2...

having a 7427 is good news for you, they are easily the most accessible units. I believe all of the $0D stuff is directly usable, though they're usually setup for V8 calibrations.

you may have an early OBD2 application, you would need to describe the PCM, take a picture of it or at least grab part numbers off of it to see what exactly you have of the ~3 PCMs that were used on 95 4.3 S-trucks.

okay, somehow I remembered to actually check this thread, I have some info: A097 appears to be the correct stream for a 90 2.5 a-body, the 7748 appears to put out a continuous 160 baud datastream whether anything is connected to the ALDL line or not. it can be put into an 8192 baud mode, but the doc...

hard to find time to get anything significant done during the week, not enough time. if you can post here again or send a PM on sunday, i'll see what I can find.

Need help with my application. 1990 Olds Cutlass Ciera. 2.5l 4cyl Iron Duke. Single TBI. ECU 1227748. I see one listing for the 1227748, but it says it's for a 2.2l. And the bin says TBD. If I am not supplying enough info, please advise. I am new to this. Can you help me? Thank you It seems that th...

that may have some use for you.

the 91 could have a 1227747, 1228062 or 16144288 ECM. ADS/ADX file needed will depend on which ECM is being used. should be hidden under the dash on the passenger side, not sure if it will be in the kick panel or just tucked under/behind the glovebox, been a while since I've been in a squarebody S10...

need to know year, exact engine code and possibly an ECM part number if those two don't narrow it down.

i use the Madtuner flashing program. http://www.madtuner.com/index.php?page=shop.product_details&flypage=shop.flypage&product_id=64&category_id=40&manufacturer_id=0&option=com_virtuemart&Itemid=26 if you want the ability to flash the 94-95 LT1 PCM as well, there is the "...

choose which one you want to monitor/interact with and select that ADX.

if you really wanted to, the streams could be combined to have all data streaming at all times, but that's a bit extreme for most people's needs.

A138 A150 those are two definitons that apply to your truck, 138 is more or less the engine half of the PCM and 150 is the transmission half. you'll find both ADS files here, which you can convert to ADX pretty easily, just have to perform a slight change to the reply settings for the given datastre...

all of the calibration changes can be done by tunerpro with the P66 V6 XDF, though you'll have to choose between a couple software packages to use to upload the calibration to the PCM. madtuner or tunercat both had had packages out for a while and recently steveo on gearhead-efi.com has been releasi...

most of the moderation team from pcmhacking is actually on here as well...

The1 looks to have posted here most recently, so I'd point you towards his direction.

one of the delcohacking.net (now pcmhacking.net) crew could answer that in a second, I'm not too familiar with the Aussie applications though.

should be able to just download the 1F ADS and import it into tunerpro V5 and have it functional.

with that ECM/code, you'll have a road speed constant and an instrument panel pulse divisor. the road speed constant is how to correct the speed the ECM is seeing, the pulse divisor is to correct the 4000 pulse/mile speed signal the ECM generates for the instrument cluster. be aware that you only ha...

what you're seeing is the effect of a 32KB BIN that is accessed in the top portion of a 64KB addressing space. just add/subtract $8000 to your location values(depending on what you're starting from) and that should get you where you need to be.

graph scaling is a function of the ECMs code and not necessarily easy to change. some applications only require changing specific values in the algorithm to get new row/column spacing, but most others require entire sections of algorithm to be replaced.

your truck is actually more OBD2 than 1... the data link connector carries a VPW(class 2) datastream, might be able to give a UART stream, the VCM is OBD2(or OBD2ish, at least). starting in 93, certain 4.3 S/T trucks got some variant of it. the more common one is the 16184738, which seems to have be...

for your application: 2 is one of the serial data wires, looks like class 2 VPW. pin 9 is also a serial data wire, the normal UART setup as used in most 86+ OBD1 cars. 13 is a circuit that runs to the transfer case. 16 is a 12V feed. for an OBD1 application(that just has an OBD2 connector, as some 9...

the issue is that two different sets of hardware are necessary here... the OBD1 stuff just requires a UART to USB bridge, while the OBD2 stuff uses a VPW protocol, with its own hardware requirements. the ELM327 is a common chip for that usage.

if it is the OBD2 unit, you'll need a cable capable of reading the VPW stream it likely pushes out.... I ASSUME it uses a standard OBD2 PID request system the way the full OBD2 implementations do, if so, I would think any basic cable would work. a lot of software options, including the OBD2 plugin f...

that might be the early OBD2 PCM?

I was certain I sent it.... looking back at my PM logs, it appears I did not. I just sent it now, if you have any issues, let me know.

the EGR is tested by the ECM while coming down from speed with little to no throttle. it monitors the MAP sensor, opens the small solenoid and watches for a change in the MAP signal. if the signal change is large enough, it considers that solenoid good and moves on to the next. after testing all 3, ...

i don't mean to dump on anyone's tuning capabilities without reason, but this wouldn't be the first time I've heard about one of Ryan's calibrations for a 60V6 being finicky. the reason the MAT value was red was likely that I setup an "alarm" limit under where you were seeing. it isn't nec...

https://www.dropbox.com/s/ep4wuzdq4bemq54/A1.adx?dl=0 there is my A1 ADX, which has the mode 10 command in it already. pump voltage showing 0 and running, I would look at wiring as well. on a 1227730, should be pin E13 for the fuel pump voltage feed. that can actually cause some problems since some ...

http://i.imgur.com/fIX47XN.png if you have sendable commands in your ADX, you'll see something like that. if not, you'll just have a blank box. happen to know what mask the ADX or calibration is? I imagine it is going to be 88 or A1, both of which have the ability to send a clear codes command. with...

https://www.dropbox.com/s/q10dtjezoecez ... 6.zip?dl=0

this is the ADX I created/use, I don't know what you're running now, but this version shouldn't have any quirks to it.

your MAP sensor needs sorted out before anything else. that and the crank sensor are easily the two most critical sensors on the engine. for the moment, I would block off the EGR port to eliminate the possibility of a vacuum leak or an EGR valve stuck partially open and causing recirculation at all ...

my dropbox/definition.

sorry, that PM slipped my mind after a browser crash, i'll get around to it now.

most likely either A1 or 88, I don't know what Ryan works with for 7730/60V6/fiero applications. if you have a copy of your calibration, you could figure it out without too much trouble. alternatively, you could download and try an 88 and an A1 ADX. I've worked extensively on both of them. i don't t...
