Hey everyone whats up?

I am going to start doing some tuning with a buddy and need to know which bin file to start out as a base map with.

We will be using TunePro RT with an ostrich emulator, lc-1 wideband and a chip burner. I am not sure yet what else will be needed to start tuning. Do you know what will be needed for datalogging with TunerPro RT?

Im not sure of my ecu code yet. I will check that tomorrow, but if need be, i will swap to a 227 or 230.

but anyways, i have loaded up tunerpro RT and the only .bin files are "apyp" and "arap"

i know neither of those is a .bin file for my setup that will work well enough as a basemap, so does anybody know which .bin file will suffice as a good basemap for a 5.7L TPI? My motor is no longer a tpi setup, i removed it and installed a holley stealth ram.

thanks everyone

also, my car is a manual. setup is in my sig

 

I would start with AXCN. Which is a y-body 6-spd BIN. MaskID $8D for the '7730/'7727 ECM.

Then extend the VE table peak into the higher RPM areas. The HSR will be making power to a higher RPM then a TPI setup. This way it won't lean out during the initial tuning.

Don't forget to change the injector flow constant to match the injectors.

Will this bin put the tune "close" to begin with or will it require lots of adjustment to make accurate. Everyone has been saying that the s_aujp would be good but I would need to change a flag setting from auto to manual tranny. I haven't figured out how to do that yet though....

But anyways, how much trouble would you expect starting from scratch with the axcn bin? And also, how would you go about extending the fuel tables accurately?

 

No BIN is going to be close to your setup. The best you can do is to start with the base calibration that best matches your engine. Then tune from there.

This is the main reason I didn't recommend S_AUJP. It is an automatic transmission calibration for an iron headed motor. And there are a lot more differences between a stick & auto trans calibration then a couple of flags.

RBob.

 

awsome man, thanks for the input. Which motor is this bin from?

 

'91 Corvette, L98, TPI, 6-spd

RBob.

 

well I'll be damned! That sounds better than the aujp. And just to verify, it runs on the $8d mask with the axcn bin?

And one last question for now, will the 27sf512 chip (28 pin connector) work on the 730 ECM? I'm assuming so since the ostrich works with the 730 ECM.

 

I found the HSR and the Miniram both required a ton of fuel at tip-in. I believe that is Map~VS~TPS on AE.. Otherwise both setup's get a severe lean pop on acceleration

 

So on the map vs %tps will adjust tip in? I'm sorry but what is ae? I'm new to this.

And I'm assuming you are talking about tuner pro correct when you speak of adjusting the map vs %tps?

 

Yes I use TunerPro RT with an autoprom. I learned the hard way because there was alot of popping after I installed the mini-ram. Learned to adjust the Acceration Enrichment (AE). The car AE uses the Throttle Positiion Sensor to get the initial enrichment 1st to get going then uses the Map. Takes a bit to screw with but once you get the right amount of fuel close, you can adjust from there to fine tune it.

 

got it! i figured thats what AE was but wasnt sure. Im new to GM tuning.

-But, did you have to adjust the whole range of values in the table or was it at a certain %tps that was more prone to "popping" than other %tps positions?

-Im looking at my tuner pro right now and it looks like what you are talking about is "Enrich Accel Delta MAP Enable vs TPS. The %tps is a constant value and the map kpa vacuum pressure is the variable? Its kind of strange that all of the kpa values are the same....

-Also, does anything with PE (power enrichment) need to be adjusted for finer tip-in tuning or is tip-in mainly controlled by the AE (im assuming it is ONLY the map vs %tps adjustments that need to be made, not the other AE adjustments dealing with AE. for instance, the map factor multiplyer vs tps doesnt need to be cahnged to tune the "tip-in" correct?

 

Yes, that is using the $8D MaskId. Note that the y-body calibrations have the oil temperature sensor set up. Just need to disable the malfunction code for it as the f-body's didn't run one. A simple flag to un-check in the calibration (using TunerPro).

The '512 chip will work. Since the $8D mask is half that size will need to either stack the BIN or offset burn it. TunerPro can stack the BIN, your burner can do an offset burn. One or the other, not both are needed.

RBob.

 

i figured some sort of offset would be needed for the burning of the chip.

Thanks for all of your help. I hate to keep asking questions pestering, but this is how i learn....but i do have some more questions

Is the oil temp sensor the only difference between the y and f bodies? I mean, when i open this bin and mask and burn download it to the ecu with the ostrich, will it run without an ses lights? I know i will need to tune it and everything but im asking if it will actually run and idle with no error codes? thats assuming i disable the oil temp sensor in the bin.

 

As far as I recall that shoul dbe the only item to set a SES light. Although depending upon how far out the tune is a MAP HIGH code 33 could pop up. Best to pull over and key-off for 10 seconds then restart is it happens. It usually occurs at idle when it does occur.

If the cam is ratty enough wil need to bump the threshold for the MAP High DTC up a bit.

RBob.

 

I'm having trouble finding the oil temp sensor flag to uncheck in tuner pro RT.

Im guessing its under the flags/swithes sections of tunerpro? Is there a special name for it that im missing or what?

also, i cant find anything about the MAP high DTC threshold. DTC means diagnosti trouble code correct?

Can you point me in the right direction to find these two settings so i can disable the oil sensor and also turn the threshold up on the MAP high DTC is the need arises?

thanks

 

For the oil temperature it is malfunction word 4, bits 1 & 7. Oil temp high & low.

DTC 52 & 62 (diagnostic trouble code is correct).

Just un-check those two bits of malf wd 4.

The MAP high is this one:

L8284: FCB 218 ; DRIVE HI MAP/BARO RATIO THRESH, 0.85
; ARG = RATIO * 256


RBob.

 

thanks alot man....youve been ALOT of help

im sure ill have more questions just to verify i unchecked the correct setting

 

well maybe im a complete idiot rbob, but i cant find those settings you are talking about.

i open tuner pro and i open the acxn bin with the 8d mask. The program shows 3 boxes on the left of the page.......constants/scalers, flags/switches, and tables/functions.

Now, I'm assuming that this malfunction word 4 is somewhere in the flags/switches section, i just cant find anything that says malfunction word 4 or high and low oil temp settings to uncheck/disable.

i just see stuff like "switch 16 (VATS TCC-R 4th-NO VATS OLP) - Bit 7- B7"

so out of that whole list of flags/switches, which is for the oil temp sensor?

is it located somewhere actually in the hex code?

thanks and sorry for this if I'm just an idiot. Im not used to this tuner pro stuff. Im more used to looking at crome for hondas while i watch my buddy tune his car......crome is a little different than tuner pro because you dont really mess with anything dealing with the code of the program.....

but hopefully someone can help me figure out how to disable these stupid sensors

 

my guess is your .xdf file for the $8d does not have the bits he's talking about definded. you will have to enter them yourself at those addresses or find a .xdf that has them.
