I have my BHAS box back, along with a memcal: 5884 BHRD 1193354
Is that memcal going to do anything for me?
My box is on its way, along with some sort of a blue memcal in it. I just drove 250 miles, 13mpg...when I used to get 17, hmmmm.
Chat amongst yourself til I find out what I am getting. ;)
I figured that. Trying to get my old box back now.
I might have access to a blow motor Suburban, but its a 95-96. Would that work? Not TBI though.
I take it my BHRD isnt going to work? Must I get my BHAS back and then try to find any random memcal for you to burn to? Appreciate your help!
Stock engine, according to engine builder. I've questioned them multiple times and they said it is stock. That was my original PCM, which I traded out for this current one, as a test. No...
Understood.
Now, I need to find a different memcal. What are my options? This is just for testing purposes only, at this point.
As far as indexing the cam, I did not, it came to me as a long block. "Assuming" the builder would have done that.
Too many different terms, I am getting mixed up. The "box" was given to me to...
The ecm was a donor that I tried. The memcal is the one that has always been in there: 1263167
Heres pix. Mind you, the box was changed as a test.
Hopefully the number you want is there. I googled those numbers but come up with nothing....hmmmm.

I've carb cleaned everything looking for leaks. It doesnt per se "need" it, it just likes it better, its more free. Like any small block Chevy I have ever dealt with.
It is. I've checked it for leaks too. What are you thinking? Remember, its still only for those 30-40 seconds. ;)
Something killing spark to one hole, temporarily? New wires, new plugs dont help.
Sure, you give it throttle and it cleans it up, 1500-2000 rpm probably.
That is correct.
In the meanwhile:...
The more I think on this, the more I am thinking prom. If I can find one to try, anyone that will run a 350. I dont even care about drivability. Just something to try.....
I think my new workout is going to be climbing up on the thing and stretching for the distributor!
I tried, all it did was make things worse, either way. Where its at is actually the sweet spot...
On older things I would set timing by ear mainly, or by vacuum. I know, you cant do that on this but its tempting. I'll disconnect the o2 and see what I get. Should I disconnect the timing wire...
If it was the cam, why would it only last for 20-30 seconds? If I could somehow edit the first minute of running time, I'd have it licked. Maybe I should create a vac leak to test.
I never...

I talked to the builder at length, it is a copy of the GM cam. He said there was nothing changed or special.
It doesnt, but it is the OEM one.
I should have said "when you see the numbers change, thats when it happens". :) Actually, it varies on ambient temperature but you are right, I was giving you a rough number.
Developed a...
Sure thing: 93 Suburban, 5.7, 4L60-E, 4WD, 3:73's I dont have ecm or broadcast code. Its still a daily driver at this point in time. Yes, thats how long it took for the thing to start running...
Greetings,
Your mission, should you choose to accept it, but I warn you, it will be tiring.
Hoping to find someone who can read GM TBI logs and know what they mean. Long story VERY short: '93...
