I have been running my race trim PCM in the car for quite some time. I just set up a new PCM and forgot about the RPM limiter. WOW. The car will pull a lot more Rs than the OE rev limiter will allow. I have to shift Way sooner than I have been with the race PCM.

Ryan
If I would have run this stock 99 STS VIN 9 program in my car before any thing else. I would have seen what you were talking about. OMG torque management that just about kills the car at WOT shifts and it slides into gear. First it backs down the timing or shuts down some cylinders. Then it starts a long shift. This is not at the same time rather one after the other. This stock programs sucks in a Fiero and I can see how a Fiero guy would be unhappy.

Ryan and Will I have been working hard on Tunes for Northstars. I have lost more 96 to 99 PCM's than I could have ever imagined. The thing is I am working on 00 to 03 programs. I am using a new download protocol that the older PCM do not like. It may work 10 times and then poof.
Any way.
Check out these numbers.
02 DTS
This is a PM from a customer.
I thought I would put the DTS on the dyno before I got my Corsa cat-back on. My car is stock with the exception of a K&N air filter (on sale at farm and fleet $36 bucks!) they put my car on their Mustang Dyno and here are some numbers - I'll scan the sheets soon but here is what we came up with:

Top Speed: 154

0 - 60: 6.28
(twice in 3rd - got better times when not in drive...)

1/4 mile: 14.53211 @ 93.80144 mph

wieght entered was 4000lbs.


We had a hard time with cooling the engine and getting the intake temp down. He said we could've had better #'s if we ran cooler, but I didn't want to stand around for 1 or 2 hours. He had a huge fan out in front of it too.

All thank to Ryan.

I found a way to enable first gear starts on 96 to 99 PCM's. This is a permanent setting. I have just a couple of codes for stuff not connected.

Can you do anything with the 96 Aurora PCM??

YES.
Don't get your hopes up too much, but YES.
I have an OEM program you would like. I will email you the details.

Thanx AJ,,,You have mail.

What year are you looking at?

'96

I swapped in a set of 3.71 gears. I spent less than 1 hour to do it.
Bad thing is it messed the car up bad. (Hits the rev limiter about 10 times before it will shift)
Good thing is that I have the technology to fix it. New program for the PCM.
If I have any time to do it with all the others that I am doing. I have 4 PCM's to get out this week end.

I finished up the PCM's and knocked out one for me.
I forgot to enable first gear starts. I will do that tomorrow.

First run out. I just got the first gear start back in and the fuel trim enabled. I need to map out the fuel trim yet and make sure I have it correct.

AJxtcman,
Could you help me with programming for an 98 Northstar to run with a manual transmission?
I also have a 95 ECM and harness, I could go that way too.
I am just looking to turn off everything except engine controls and emission controls.

I am still on hold on the 93 to 95 Memcal.
I have never seen a GM dealership without a RS232 card for the Tech I or a Tech I - A. The Tech I - A equals Tech I with a built in RS232 card. Now I am waiting on a new tool.

New candy.
OK old stuff made to look good.

How hard was it to swap in the 3.71? Did you do it in the car? I need to do the same thing but the whole transaxle thing is a little different then what i am used to. What all did you have to replace? I just don't really know what to to buy.

Totty take a look at this thread. It has some information. Every time I do a swap I forget to take more pictures to add.

I have my car running on the LS1 PCM. I have a bug to kick out of it. It sound great at least

someone wants to give me a blower for my car

Can I enlist some help on making an adapter plate?

This will be from a 6.0L 03 to 06 Escalade. low mile/new blower

I have a spare intake for both.

My new PCM venture will support it.

I have only one friend in a machine shop and I don't want to get him in trouble working on a side job.

How about it?

Wait this might be a front mount

I have it and will need to mount it off the front like this

It has 1 bad bearing and I have ordered it.

The Blower Is rebuilt and am working on the mount.

very nice
Few people use centrifugal superchargers, I would imagine that they would be easier to install than a turbo.

It was Free.

I gave FieroWannaBe a test drive the other day. The car used to shift into 3rd about 100. I mentioned that we were cooking along pretty well getting it into 4th from a stop at WOT. Then I realise the gear ratio error. I guess I hit 3rd about 85 mph now and 4th about 140 mph on the test drive. It was cold -6° and I had no heat. 140 in -6° weather. Hmmmm wanna go for a test drive with me?

I fixed the heat yesterday. The Car was a non A/C and when I got it the guy had added A/C, but the hoses were wrong.

I was running the new gear set through the calculator and this is what I came up with. I swapped out the 3.11 gears for some 3.71

This was the shift point with the stock PCM.

RPM--1st Gear--2nd Gear--3rd Gear--4th Gear
6500------54.8-------99.84-------162.3-------238.4

This is the new gear ratio and the trans shift up to 7000, but I would say some place between 6400 and 6700. We ran it to the end of 3rd gear. Going into 3rd is now is 82 to 90 mph and into 4th 134 to 146 mph.

RPM--1st Gear--2nd Gear--3rd Gear
6000------42.4--------77.2-------125.6
6100------43.1--------78.5-------127.7
6200------43.9--------79.8-------129.9
6300------44.6--------81.1-------131.9
6400------45.3--------82.4-------134
6500------46----------83.7-------136
6700------47.4--------86.2-------140
6800------48.1--------87.5-------142
6900------48.8--------88.4-------144.5
7000------49.5--------90.1-------146.5

Bump, for a well done car.

I have been sanding the intake down. I will have it painted soon. I am thinking Yellow. hmmmmmmm

I purchased a Stainless rail today.

We all know that I am installing that blower and this set up will help




plans for the bulb





I sealed up this valve, but now I need to make it a 4 PSI blow off valve

[This message has been edited by AJxtcman (edited 02-07-2008).]

It is in the paint booth. I hope to get it back today

Dude where's my car?

quote Originally posted by AJxtcman: Dude where's my car?

looks like an inside out twinkie

That pic reminds me when I went hunting in my fiero. I just did not have a choice. The samurai diesel was in another city. Nancy had the suburban and it was the last day. So, I chained up my fiero on the rear and took the 87 GT hunting. I drove up the logging road and parked. Bushwacked up to my favorite place and it snowed the entire time I was up in the basin. Came down and found my fiero under 13 inches of snow. I barely, and I mean barely got out and home. I kept high centering on the snow simply by driving the car and compacting the snow. it was wacko. Lesson: don't let your judgement be swayed by desire. Never use a fiero to hunt in out in the woods! LOL!

Now your car is under some real snow. And its cold where you are too!

I am supposed to go to the dyno on Saturday. Hmmmmm
If I get it out it will be a mess by the time I get it to his shop.

The intake is painted and on the car.


Bare intake on the car.
