Not trying to detract from or hijack, but wanted to ask Fast if the bin files on Moates site are from your engine when you had the Vortec heads and ZZ4 cam in it?
Still waiting on my heads to get out of the machine shop, have been looking over bins and .xdf files on TunerPro, trying to decide which would be the best starting point, and yours seemed like it might be the closest to what I am gonna be running.
I can load a $0D coded chip into my '8625 PCM and it will work, correct?
I never ran the Vortec heads and ZZ4 cam concurrently. I have always been running a custom grind cam with the Vortecs. It is an aggresive hydraulic roller with 216/228 @ .050 and a ton of lift.
The bin file on TGO is with the stock 350 in a Van. Stock heads and stock cam.

Ah, my bad. I never checked out the file on TGO, only looked at the ones on Moates download site. I looked again and had misread it. It said something like "1995 Fullsize Van 350TBI_4L60E" with additional .bins for "Modified" and "Stage1". I forgot your van is an older model. My apologies for the misunderstanding.

Hello guys, I make few datalogs with Fast355 SA table, car runs pretty good , good acceleration with sometimes "thinking in 1400-1800 rpm range" , at this time i think to rise a little SA in 85+KPA load from 1400 to 1800 rpm , edit VE and , and back PE with TPS to normal settings and see how shes run.
This is additional BLM for previous message
Fast i set AE Correction vs. Coolant to 1.00 in trouble area. but shes sneez again when thermostat is opening,after few min of opening thermostat shes ok
Hi there. I drive today with standart TPS treshould and have a problem , she does not want accelerated sharply , during a smooth ride everetyng is ok but when i put pedal more than 50% shes sneez then think and accelerate fluently. also I can not sharply start , I can not skid. BLM is not bad . maby its SA ? but should i rise it or lower ?
And i found some interesting problem , why my can not have timing advance at all ? how it can be? Ignition Control Module is new , ESC is absolutely work , everything grouned , wire harnes is ok. Can in be a problem in bin ? becouse we check everything onder hood
Hello, I have a 1988 camaro rs originally a 305 TBI that has had a 350 TBI swapped into it by the previous owner.
I checked the ecm and prom and its running the factory 1228063 with a 24pin hypertech 305 chip. Unfortunately I managed to break one of the pins off the chip trying to get the plastic holder off of it.
Couple questions I had. I know the 1228063 was only used in the 88 camaro. Is this going to cause me a problem? Should I see if I can get a 1228746? (Will this even work?)
if i can stick with the 1228063 what ecu/xdf and bin should I start out with?
I downloaded the 1228063_rom.zip and 8063.ecu file from moates.net but its a bit confusing.
uhh yeah ive been reading this article up and down for a while and know some of what you're talking about but what does all this do do it make the car faster and if so what gains could i expect out my a bone stock L03 motor out of a 92 camaro rs
Hey guys i have a gm 350 tbi in my jeep wrangler. it seems sluggish lately and throwing an est code. i was hoping to post my info and have you guys check it out im pretty new to the aldl. i understand blm's some 128 + - 3 is good and over 131 is getting lean rite?
ok while i was logging i was throttle happy but hopefully this can give you some idea of where im at!! oh by the way the exhaust is rich smelling and below are the specs pretty much all stock..
engine 1990 gm tbi swirl port stock heads(these are actually good offroad
headman narrow headers like 1 1/2 i think
dual flowmaster super 44 series no cat's
TBI spacer
4.10 gears
art carr 700r4
35" tires
ok i usually use excel im new to forums and files..lol ..i did attach from notepad and that seemed to work. anyone need different format just walk me through it!!

Reason: log files
I looked at wide average. I see BLMs from 124-132. that appears normal to me. 124 is not rich and 132 is not lean. With NB02 feedback car is running at stoich as long as BLM are within the range ECU can work with. There is always room to improve the underlying VE tables. this morning cool temps(60d f) here and I was seeing BLMs over 128. I expected that. This PM on ride home in traffice I will see temps at 80F and most likely BLMs at 126-130.
EST (electronic spark Timing) im not exactly sure of the code #. it was an error flag on win aldl. i did unplug the (est) wire the other day to set timing maybe that set the code?
It just smells rich, seems a little sluggish i hope to be able to send you a log file that you can read later when i get home tonight. And just look at at when u get a chance!
I see EST in your reply. missed that. disconnect the battery for 30 secs. May go away. I assume it is connected. I believe you can check EST function with a timing light.
Are you running a appropriate distributor?
Should not be runnin rich as your BLMs are OK. Maybe your AE needs to be addressed? I will assume you are idleing CL so that should be OK as well.
be all i need besides the chips to tune and hold x amount of tunes on 1 or 2 chips?
Like can i have
#1 stock tune
#2 modified
#3 Race
#4 Valet
#5 and so on
How many different tunes can i hold on 1 chip? this cant be! sounds 2 good to be true
1 @ $85.00 burner
2 @ $5.00 Flash Chip
1 @ $40.00 G2x switch adapt
1 @ $25.00 Remote control
1 @ $00.00 usb cable i already use to log
1 @ $30.00 Software donation

So can i really do all that for $190.. that sounds like a pretty good investment.. please fill me in on the catches??? lol
Im in the process of rebuild w/ mild comp cam and ported heads, im starting to worry it will run like a** without doing some tuning.. engine was out of 6.5k pound truck now in 3.2k pound jeep.. i keep putting tuneing off. plus i need to have this baby ready for an mud bog event in 3 weeks. so does my shopping cart look ok? i know i cant tune and drive like this, but im just trying to start someplace without a load of cash tied up?? please give me your opinions.. should i just use mail order chip rite now? can i start tuning without dataloging first? like will anything save me time later while im waiting on the heads to get returned to me?? thanks for the help!!
Yes, that's all you need. I would not even waste your time witha mail order. After you get all that stuff you just need a little time to do dome datalogging and burning. Follow some instructions at the beginning of this thread and you will be up and running in no time. Trust me, I hae done it.
I have been a member of this site for quite a while and gotten tons of information. I would have never gotten this project of the ground without all the stickys and reading and searching forums. I have a 1227747 in a Chevy Corvair w/Dual TBI and DIS ive been running for about 1 1/2 years. Car runs pretty good and but not the peformance I was expecting. (some say the same as carbs)
I see people post the logs from WinALDL and the brains of the forum look at the logs and adjust the bin. Im wondering what as they/we looking for in the logs? I know If we see a knock at 80/2400 RPM, we might want to set the timing back in the SA table and of course get the Fuel Tables done first.
Im starting a new comptuer (1228746) on the Corvair because of the timing issues. I reason that using the IAT may help control the timing as with an Aircooled engine the temp are all over the place and hard to control. When I was using the 7747, I would get it all good, then on a 85 degree day, the knocks would start, but at 75...was fine.
Im not wanting to steal the holy grail, but was wondering what I look for as I drive this car daily and can make tons of datalogs... but I want to make sure Im getting all I can get out of it without pinging its brains out.
Thanks

Reason: Typo
I would agree KC at 80 map could very well be too much timing. KC on moderate acceleration map< 60 might be mechanical in nature.
as far as air cooled engines you are correct to be cautious of excessive timing and lean on A/F. Are you aware you can increase(enrichen) the A/F so as to run in CL a tad fatter than stoich? I have some experience but very dated on air cooled snowmobile engines. One is often too lean or too rich. burndowns can occur at any throttle position. I wonder if any VW owners retro'd their engines to EFI/TBI? crazy thought on my part !
when you say ping I assume you hear the ping audible as motor is near your ear. One way to check on timing is to add 104 octane available generally locally. I am fortunate that I have 2 stations near me. when I have time and $$ I will fill 50/50 92 and 104 oct and see if I can induce real knock and play with SA tables. right now I am certain what i experience is 100% mechanical.
Q
I am using 1227747 ecu Ver, ASDU . I selected my 42.XDF and loaded up my stock bin. Well im looking to start editing some simple stuff like my Rev Limiter and there is no constant for it? on some other XDF's but not the 42 i seen a cut fuel constant and a resume is this the rev limiter. i would like to know the factory setting and adjust. i actually would like it lower.. Can someone please help me with this? I have a few more q's but i dont want to give anyone a headache!!i think ive read this thread 5 times but still just retaining 30%.. thanks all
Change to these values
Addr: Value:
$D414 $00
$D415 $AA
$D416 $00
$D417 $AB
What we have done is told the ECM to look up another value other than the PROM ID and put it in the ALDL stream in its position. The thread listed above also tells how to put your total timing into the ALDL stream, very handy. Now our Prom ID field in winaldl will give us a raw hex value for our PW, we then have to take whatever value is displayed and multiply it by .01526 and add in the injector bias value which can be found under the constants menu. This is where putting your log file in excel comes in handy. You can set it up to do the simple math for you. Ok so now we can do a log and see what our PW is getting up to. To get your PW as a % just divide the time available by the time used. The generally accepted limit is 80-85%. Since Rbob already did the math we know we’re going static. It will be a good learning experience to go head and log what static injectors look like. You’ll see the O2 peg rich/lean and feel the loss in power at whatever point the injectors go static.
Can i use this on the 7747 ecm so i can show PW and SA??
