I'm very new to tuning so please bare with me. I have a '87 vert with a '90 l98 383 stroker. I have an ANHT memcal in the ecm which I assumed was a stock tune but when I burned a chip with a stock ANHT bin it wouldn't even start and it gave me the sys light by the tacho. That completely confused me cause it should be the same as the memcal My BLM reaches and settles at 160 after a 20 minute drive and so I want to tune that to spec and I want to tune whatever I can to get best low end torque performance. Anyone have advise for me?

drive it

Lets start by identifying what you have.
You say it's an 87 with a 90 383. The original 87 was mass air flow, 90 speed density. Or does it have a maf still? Or been converted to a 730 ecm with map?
Just because there's a sticker on memcal doesn't mean it's that stock program-and seriously doubt it would run for poop with a stock program if it's a modded 383.

Sorry I should have been more specific, the sticker on my ecm says 27 on it but I have a map and no maf.

this is congruent,your 90' 383 is a speed density engine with a 727 ECm:your 87 is a map/speed density converted car.

You probably have a custom tuned chip,specially a speed density 383 modded engine doesn't tollerate a stock chip

i don't like to see an engine running super lean at 160 blms.

I'd like to pull my bin from my memcal to look at what's on there but I don't have moates adapter for memcals. I have the apu1 with a G1 adapter. There's no way to pull the bin from the aldl cable right?

tunedport85inject

usually to read the eprom you use an eprom burner,the software you use to burn an eprom has a read option so you can extract the .bin

Christian95

Right, I have the burner but the chip is in a memcal which won't go in my burner

i have an 85 with a different eprom carrier,but i know that your memcal has an eprom inside that you simply can take out

tunedport85inject

is this soldered?

Christian95

Mine looks pretty secured in there. I think it's soldered in

Edit: Just saw your post. I believe mine is soldered

tunedport85inject

are you sure? have it in your hand,from this pic it seems to be press fitted

Christian95

Maybe you're right. I'll take mine out and see. And thanks for the help so far!

tunedport85inject

Christian was the car running fine with the mounted chip ? why do you want burn a new one? do you have a wide band gauge?like an Innovate LC-1,this is very helpfull. you need to know how rich or lean you are changing your fuelling maps.good luck

ps here atutorial for the Willem eprom burner and his software

Christian95

It's running but not to the spec I'd like. I keep getting an EGR code but I have EGR deleted. My main goal is to tidy things up and fine tune my BLM's and other things. I don't have a wideband

Christian95

From what I see on mine and what I'm reading, the legs of the chip are attached to the memcal and I'd have to desolder

do you use Tunerpro RT? make some datalog ,at normal cruise speed and rpm and at WOT and report your BLMs,let see how is running this bad boy...

tunedport85inject

i have an Ostrich 2 from Moates,as you probably know this is an emulation device that works with Tunerpro RT.you need an adapter and you can simply connect it to your ECM and chanhe your .bin parameter on the fly while your driving the car (have an assistant).While you change paramenter you can see how BLMs change, then save the new updated bin and leave the litttle box connected to your ECm.No more need to burn a new chip,since you can use the Ostrich as a solid state memory device, turning your old ECm into a "new" flashable unit.

Christian95

Yes I use tunerpro rt. I have a log from last night I can look at. Do you want me to post the log or just tell you the blm's.
And yes I'm familiar with the ostrich 2. I have the apu1 and I can emulate as well but I'd like to see my current tune before I start changing things.

tunedport85inject

post some BLMs vs rpm and O2 reading,i use the stamp button on my laptop while i'm playing a log and i take screenshot ( control V on microsft Paint and save as Jpeg )that i can post,so you can show all data from tunerpro dash as a pic, example
