    94 Roadmaster Estate .bin

    Hi,
    Recently uploaded the .bin file from my 94 Roadmaster Estate using EEHack. The car is entirely stock with 123000 miles and runs great. I thought it may help someone else so I figured I'd upload it here.

    Please note I have not personally tested it by dropping it back into the car, so use at your own discretion.

    I'm trying to do some light mods to drum up a few extra horses so any tips or tricks would be greatly appreciated.

    Thanks!

    It looks like your read is good.

    Attached is your modified .bin file. I've been able to get away with this aggressive spark table but definitely watch for spark knock due to the roadmaster being fairly heavy. I changed a couple transmission parameters you might like too.

    Mods, if this is not allowed, please let me know.

    Thanks for that! Please forgive the question since I'm pretty new to this. I looked at your spark advance table an it looks like you really bumped up the low RPM advance settings. Do you think it would be safe enough to give it a try on 87 octane or should I run higher test initially?

    Last night a compared a .bin from a 94 Impala SS and used that as a start point for transmission shift points and spark advances. Also did a couple small tweaks like disable the air pump stuff, ect...

    Maybe I'll go a little more aggressive than the impala tables but maybe not quite as far as yours since I haven't had a chance to do much to the car over stock.

    Also your shift points look good, i'll give those a try!!

    Thanks again.

    just for fun i compared your bin (factory cal id 16230221) to the one i have on file and found some differences, i wonder which one is truly original (mine has the air pump disabled, which i think there was a factory service bulletin on)

    that spark table above is way too much timing advance for iron heads in my opinion, it looks like an aluminum head table, but if it runs smooth and doesn't knock, go for it...

    it's not necessarily the healthiest thing to run spark advance right at the limit, either, especially with fuel quality being so variable these days. just log with eehack and run the analyzer after, you will clearly see where the knock is occuring

    i think the most power to be gained is in power enrichment fueling which is insanely rich on a stock b-body, i've seen guys with widebands going richer than 11:1 with the stock calibration. assuming your fuel system is healthy you should be able to pull at least 5% or maybe even 10% across the entire power enrichment table with no issues, i would also install the blm locker patch.

    Good to know for sure. I know my air pump runs but i plan to pull it all out because the tube leading into the header is broken.

    I'm going to start with a spark table closer to a stock. I made one up that bumped up the advance 1-5% starting with the stock and comparing it to other similar bins.

    Just to clarify when you said "pull 5-10%" on the power enrichment table, subtract 5-10% across all the values but which table is that? I am using the EE.xdf in Tuner Pro.

    Probably my most important issue is the comm errors, see below. I am getting these in EEHack, engine running or off (much worse when running) Happens every 3-10 seconds. Afraid to try to download with this going on. I was surprised i actually got a good upload in the first place.

    I am using a new ALDL to USB cable from Red Devil River. Any thoughts? Wiring issue, cable issue or something else dumb I am overlooking?

    these cars are a bit of a pain, do you have 'silence extra modules' checked off in 'advanced' in settings? there may be a module such as an airbag or body control thing that's interfering with ALDL communications. some people pull a bunch of fuses other than PCM IGN and PCM BAT when flashing just for safety. personally i'd interrupt the the data wire from the ECM and run a connector there which you could disconnect and plug into the aldl cable. it's really just DATA and GROUND.

    for power enrichment in EEX, set to view by: category. then you have air fuel metering > power enrichment > PE AFR correction tables. read the notes for those tables as the math is kind of weird. these are multipliers to target AFR. best to subtract from the RPM table i figure

    So how is this used with Tunerpro and a tbi obd1 setup? I looked for the answer to that and have not turned up much. I would not use it on my van, as minimal changes to the original table were easy to do. I can see where it might be useful if you had an engine that needed drastically different shift points. I am mostly just curious what all the fuss is about.

    Bulecat will provide Tables for "Normal" Transmission Shift Points and "Normal" TCC Engage / TCC Release.

    Screen shot below is OBD1 TunerPro. OBD2 tables are "Usually" the same, maybe worded differently.

    OK Thank you for the explanation, for some reason I was thinking it was more complicated than cut and paste.

    Hey guys, things have been going well with the Roadmaster so far. I'm pretty happy with how it shifts and the car seems to have woken up a little.

    I've done a couple things so far such as an intake kit and removed the mechanical clutch fan and did new higher quality plugs and wires, next step is upgrading the exhaust.

    Attached is my .bin as of now. Any ideas to get some more out of it? Or should I leave it be?

    Would like to get some more smoke off the tires you know!

    you've done well, that's a very nice conservative first tune. if it runs well you could definitely leave it as-is

    if you had a wideband or something you could try subtracting a bit more PE fuel, but your targets are pretty good, so if your maf calibration is close, you're within a few percent of ideal AFR, and on the rich side, which is good if you have no wideband.. but in reality, i've always found it richer than anticipated on a wideband.

    you should do some logging and tune up your maf table a bit to compensate for changes in your intake.. take a log of a really nice long drive of varying conditions, at least half an hour, and run it through eehack's analyzer. it'll fix it right up for you, usually in 1 or 2 passes, and i bet its rich at low end, which is further enrichening your power enrichment fuel in that area and hurting your off-the-line power

    install the blm locker patch in EEX too, that way trim issues wont create inconsistencies in power enrichment

    Thanks for the advice! I think you are correct with the new intake I am running rich and I have noticed my off the line power is down. I took a drive to town this morning and logged it.

    I have the blm patch installed. Next steps I think would be to definitely take a look at my MAF table.

    Need more data to figure out exactly where to set them, but it looks like your blm boundaries could use some tweaking. Youre not using a couple cells.

    playing with these helped my tune tremendously for SD and im sure it can help for MAF also.

    Although yours arent as weird as some of the other factory settings ive seen in the camaros
