First time TBI tuner

**JeepsAndGuns** · 10-06-2013

That bcc comes back as a 5.0. Is that what came stock in that truck? That could explain a few issues, running a 5.7 on a 5.0 tune.

I'd like a copy of that bin when you get one!!! It's a 5.0L Manual...

Even if it were a 5.7L chip, along with 65 lb/hr cop car injectors... it would still not run well with Vortec heads = needs more spark let alone fueling adjustments.

Is the cam stock Vortec?

Mark I have a BJXP bin that came in an eBay PCM buy and it was labelled by the seller 5.0 4L60e 16197427 if you still need a copy how do I upload it. It does appear to be auto bin though from a 94 as the pwm stuff for the 95 models are not enabled. If you want it let me know how to upload it.

Also Docba my vortec 5.0 needs 10° of advance to idle well too. I can adjust the idle stop and the timing to get 0° and 650 rpm but it runs like it wants to die. When I plug in the timing set plug timing jumps to 21° advance and smooths right out. I have read that vortec head need more timing than standard heads appears to be true but I am still learning to play with this stuff. My first conversion and add to it slight engine mods so not sure what stock looks like.

Sure! Even Cal Data says it's a 5.0L Man... but it has been wrong before.

This is the bin (BJXP) that I am using for my conversion with PCM 16197427 $OD. Also will be controlling '95 4L60e trans. Engine data: 5.0, 30 over flat top pistons, 9.5:1 compression, com cam XE262H-10, 1.52:1 roller tip rockers, Edelbrock Performer intake, vortec heads milled for 58cc combustion chambers. Do you think this bin is a good starting point, if not any recommendations??? Note I read this bin directly from the stock prom and verified they matched.

I think it's a good starting point. Set the constants correctly like cylinder volume, injector size, etc., and turn off things you're not using such as EGR. That's a pretty big cam for a 305 TBI. I think you'll be able to get it to work well, but it may be tricky to get a good idle. I'd bump the commanded idle to 800 in park and 750 in drive. The spark and fuel maps will need quite a bit of work everywhere.

I've recently been tuning the L05 and 4l60E in my 1995 K1500. That pcm with $0D mask is awesome. You'll really like what you can do with the 4L60E!

I have run the 305 in my Vette with TBI before when it was in the old C10. It has a Crane 272 H10 cam in it. While it did have lower than stock vacuum at about 700 rpm the vacuum signal was very stable for a 110° lsa cam it worked very well.

The factory PCM was a victim of a bad ground according to the previous owner he replaced it with one that he claims is out of a 95 Chevy van. I need the BURN2 in order to read/obtain the BIN don't I? Also my truck is a factory 4l60 truck, how on earth would it shift with a manual PCM? I hope I didn't hurt it, that trans and the rest of the truck have 380,000 on it, I believe the old slush box to be fragile

**EagleMark** · 10-06-2013

To read the chip in the memcal you would need the Burn 2 along with a header to fit in memcal and in Burn 2
https://www.moates.net/hdr1-memcal-header-p-52.html
and a G1 adapter
https://www.moates.net/g1-memory-ada....html?cPath=64
and a writable new chip
https://www.moates.net/c2-sst-27sf51....html?cPath=26

Your 5.0L Manual bin would not be the first time we have seen a chip labled Manual and it was Auto.

I have a question, the chip says it has a funky erase voltage, but that the BURN1 will be fine. It is my assumption that the BURN2 is reverse compatible and will also erase this chip. Is this an accurate statement?

**EagleMark** · 10-06-2013

That's if you have another programmer, other then Moates Burn 1-2 or AutoProm.

Not sure why? My Gq-4x does the 27Fs512 just fine, but the only reason I have it is to burn stock chips for 1227747 type ECM which is a 2732a.

Problem with factory chips is they have to be put under UV light to erase, not done in a programmer.

I see, thank you for all this info btw

If the factory PCM has been replaced, then theres a possiability the BCC code on the outside of the PCM case does not match whats on the memcal. I would pull the cover off the PCM and see what the BCC is on the memcal itself. The original memcal could have been put into the replacement PCM.

I am very good friends with the previous owner, and am positive that the memcal was not switched. As soon as I get to some WiFi or a friends who has Internet I'll get all this stuff ordered and I'll upgrade to TunerProRT. So we can see what is really goin on with this rig.

**DOCBAWRENCHTURNER** · 10-11-2013

Well, I went to the local DQ to soak up some WiFi and got TunerProRT, also installed driver for my cable. Got home and acquired my first datalog! The first thing I noticed is this truck is idling at 19.7degrees of timing. Also the BLM is between 90 and 125, the integrator is around 120-128. And the 02 sensor sometimes just dies for a couple seconds then fires back up hovering between 700 and 815. I attempted to check the base timing, I unplugged the esc wire, fired it up and base reads 23 degrees. Shouldn't that read 0? Also it won't run and has zero throttle responce below 7 degrees As read on Tuner Pro. I would upload the file, but have no Internet at home. I think I have a problem to fix before I tune this thing. Suggestions? Thoughts, questions? Life advice?

edit: I failed to mention that I had previously set base timing with a timing light. Seems like it should have been right.
