have you opened the case of your P66 V6 ecm to find you have two flash roms on independent boards?

what's the plan for that?

are you going to buy two of these and try to run them...

that is for software-specific issues (like 'how do i do this' or 'why does it crash if i press this button' or 'why doesn't it do this'), who should be responsible for either answering user questions...

you'll never get a perfect speedometer. too many variables throwing flexible rubber at something. just aim for 'close enough for a cop'. even factory calibrated speedos with brand new OEM tires...

did they ever make one that worked? i doubt it, those things have two boards. you would need two emulators and it would involve a lot of fine soldering

when you say "read and write " do you mean the calibration?
pretty sure the 7427 is not flashable so you will be removing chips and putting them into a programmer
tunerpro rt will definitely...

people get better flow numbers (pre-porting) with the stock ports in the iron heads

they are both good heads. two different strategies.

these under hood ECMs are resistant to flood, fire, heat, and minor nuclear explosions.how you have it mounted should be totally fine.

for crusing air fuel in closed loop just do a bunch of logs in eehack, load em up, open the analyzer, and hit analyze. then scale your maf table.

same as an OBD-I but different data pin

red connector: pins 2 and 18 ground
black connector: pins 15,30,31 power
gray/clear: pin 32 ground
blue connector: pin 1 ground, pin 3 power, and pin 7...

without actually looking at the bin, there could be several reasons for negative numbers in a spark table:

- the XDF is incorrect

- the engine actually is calibrated with spark occurring after...

after almost 3 decades with all that el cheapo GM low gauge wiring, just be glad pressing the trunk button doesn't cause it to burst into flames

another issue may be your wideband calibration. are you actually looking at a gauge and your laptop while driving, or are you logging the wideband AFR somehow? if so, are you sure your calibration...

there is absolutely nothing out there that is truly good to tune your ecm

im working on a flash tool but it will take ages to complete at this rate

even when its ready it wont be a thing you...

in GM language INT is short term
you'd be best off looking at the average of the long term trim

if you're assuming that you need to log and tune in the same program - you're assuming wrong

actually having the log in tunerpro doesn't assist you in tuning in any way. it just happens to be a...

there are tons of free elm dataloggers although i haven't found a great one yet
maybe try pcmhammer's logging tool
i hear its alright

you can edit your ADX in the acquisition menu. making an adx for that awful elm plugin is really not a good project for a tunerpro beginner.

tunerpro is awful at ELM logging.

have you made an ADX file?

and you probably never will, due to how the erase and rewrite of that flash chip works. if you want realtime tuning of the entire bin, you will have to use an emulator, you wont be doing it over the...

well you could probably read the file over the aldl port with my flashhack tool.

i am pretty sure that ECM uses device F4 and is 64KB

oh and as far as power enrichment goes you have some options, but it's the final fueling outcome that matters. you can't be in closed loop during boost though, or you will blow a hole in something...

oh wait, you're still running a 1 bar map?

that wont work, not at all, and definitely not with speed density

are you running some other method of increasing fuel in boost?

assuming you are...

power hungry, eh? you changed a lot of stuff. 70lb injectors are huge, are you really planning on needing that much fuel?
do you use a wideband?
do you have logs?
is it mostly lean surging off...

in my experience a smallblock with good compression, the proper spark advance, a strong spark, and a decent amount of air will mostly start with nearly any amount of fuel you throw at it.

if it's...

the original code is 2B 02. this is a relative address branch, and moves two bytes ahead if status register is minus.

the next two bytes, which is what it's conditionally jumping over, are 86 80...
