renegade intake? for cross fires

And the ve learns are going much better with the heated O2 sensor, i set the computer to idle closed loop and let it idle while learning, i now have a very stable idle.
I also did a few learn cycles keeping the engine in the 1-3500rpm range and there is a bit of a difference when launching now, much better!

The new o2 also fixed an anoying pulse i had at low rpm cruising.

The new computer also has the ability to control the fan temputure on/off cycle.
So I'm going to run a new wire for that control soon.
 
Im glad to hear things are improving, and yes please keep adding updated posts,
so we can benefit from what you learn, as you get it tuned and working correctly
and change components and find and correct,the little faults all new engine combos require sorting out
 
Real world results with my crossfire... sharing an actual comparisons with pre/post mod data.

HLH Broadcast code SA table...

If someone wants to use 82 or 84 heads, this is the SA table to use. The 1985 Vette used the same heads as the 82s & 84s.

However, no one seems to have saved the SA table specifically for the 82 or 84 because the ECMs were so archaic. So, the choice has been start from scratch on an SA table or use a TBI truck SA table as a base. The truck table is for a heavier vehicle- to get it to work would require lots og trial and error to add as much spark back in as the 85 table has.

There is NO added spark for PE mode on this table. If you are using EBL, you can add some through the PE SA adder. I have about 35* total after 3k between the main table and the PE SA adder.

FYI, use the 4,800rpm row for any RPM higher if you find that you need an extended table value.

I can,t seem to open that last linked table posted above
 
Ah...I was foiled again by technology!! The file is in the latest version of MS Excel. I used Office 2014.

I'll upload a CSV and/or earlier version of Excel later tonight.
 
Here is an image... Shows the spark across rpm and KPAs.

An Excel version allows for easy copy/paste into a BIN.

Mine's okay at this point.

At some point in the past, it had a rebuild a suspect. And... I can access first gear with the shifter.
 
Thanks for the details.

I recently picked up a wide band o2 sensor and have slowly been working my program.

So far using it i found i'm almost out of fueling with the 80lb injectors and stock regulator spring.

I made some pretty big improvements yesterday related to 4k+ rpm and accelerating but still more to do, plus i need to find and order a stronger regulator spring or swith to a vacuum ref fuel pressure regulator.

Amd the transmission rebuild has been holding up great, i think its finally broken in pretty well and as a result i can down shift a little easier with out so much tire chirp. :)

I really love how fast it shifts, i love driving the car manually shifting, instant response to where the stick is.
 
and thanks for posting the excel document with the SA table, I had one I had been testing with some success, this one looks very interesting.
 
little update, I managed to crack my transmission pump rotor :D

Car had some excellent power with the new timing table, it was also very smooth in the high RPM.
For the SA extended I worked the table so it flowed with the other SA table, it seemed to work out very well, however I want to play with it a bit more as it came out a bit bumpy...

When the pump rotor failed I was driving in traffic with the engine in the 3800rpm range while doing a ve learn, I hit the pedal and took it to right around 5k+, manually shifted to 2nd and then nothing.
I managed to coast off of the road and called a tow truck, nice part is the transmission pressure gauge made it so there was no doubt in my mind what happened.
Minutes before the pump gave out I heard some rattling noise at the light, and then I noticed the pressure gauge was vibrating up and down very fast.

I was not to far away from home so the price was not to bad, first time I have ever used a tow service (flat bed).
I feel really dumb now for not just calling a tow truck when I overheated the engine now...

anyways it was a fun little adventure and I now have a billet pump rotor on order! :cool:
I really wish I had upgraded when I had the trans apart the last time around. :rolleyes:
 
I'm sorry to hear of the problem, but suggest, you look into the possibility that there,s an up-graded and stronger , heavy duty aftermarket replacement, and point out that when parts fail there's always metallic trash in the trans fluid that mandates the trans is cleaned and flushed out internally, and related clearances be checked.
you'll generally find it cheaper to rebuild the current transmission, but at some point you might consider upgrading to a 4L80E or similar over drive thats considerably stronger, than a stock 700r4
