I'm currently playing with tunercat, checking out all the settings etc. Ive also had my scanner (craig moates software) for several months so I'm all familiar with that part. Now I just need to order my pocket programmer (eeprom etc) and get started

I Asked about my cam over on the general tech board and got mixed opinions. I decided it would be better to ask the people who have actually tuned cars with larger cams.
Here is the cam in question..

Adv dur 282 intake/288 exhaust
Dur @.50 in. 230 intake/236 exhaust
lift .510in/.520out
Lobe separation 110 degrees

Here is my current car setup:
ZZ4 crate motor (this currently has stock zz4 heads which I believe are just stock 91ish alum. corvette heads. They will hopefully be ported or replaced within the next year) , LT1 Intake, 3.70 rear, probuilt stage 3 700r4, 2800 vigilante TC, TES headers, dynomax 3" catback , nitto DR, 125 shot n2o

The main answer I seemed to get from the gen tech board is that it is a good cam, but it's not going to be worth it because I'll never get it tuned correctly/idle decent.

A few people said that it shouldnt be much of a problem to get it to run more than decently if you do the prom burning yourself. Obviously, I'm almost there...

But my main concern would be, me going from never tuned a stock car to trying to make a cammed car run/idle well. Do you think I could do it?

I had pretty much given up on the original cam and decided to go with the comp 224/230 .503/.510 (1.5) 110 cam.
So, now I'm back at step 1 and can't decide on which cam.


I'll be using the 89 maf setup ($6E) if possible.

 

You'll have some problems working out the 89 ecm to run that mich cam. You'd say yourself alot of grief with making the changes to use a 90-92 ecm and go SD instead of MAF.

 

I have a 230/245 cam. I'm ok at tuning and I can dial in things pretty well with a 730 ... but I am no expert. It can be done and it can work very well. But, as Grumpy pointed out, ... Speed density will make life a LOT easier. I am running Speed Density.

..now you have me thinking about speed density before I waste any money on maf.

Why is it easier to tune? Are you assuming I'll be maxing out the maf?

 

Big Cams can wreak havoc on a MAF system (Reverse Airflow, low air speeds at low RPM, etc). Speed Density doesn't rely on airflow to calculate the amount of fuel. It relies on MAP.

I have a few questions ,
im trying to get into prom burning and need to - my TPIS stage 6 is far from optimal i know.
ok here it goes - i currently have an auto x-ray scanner and know it is not the best for prom tuning ,but will it do for now? or do i absolutely have to get a laptop?
my current set up is MAF and its not maxing out but it is hitting high 240's gps - i know the SD system is the favored ,but
will i see benifits from going to SD? is it any easier or harder to tune? (i see this question was answered above) and last for now ,i hear alot about WB O2'S do i need a laptop to use one ,or will it work w/my scanner -
and do i even need one or just use a g-tech?

I also would like to know if someone could explain the intergrator
function to me ,i know about my BLM counts but am unsure of what the intergrator does.

all replys appreciated.
