Tunning a 1993 LT1?

[Speed Density]

Dunno if its been said here before but at ls1tech.com people will smack you down for asking. At this point i know all us 93' guys can do is mailorders. So how would you "fine" tune a 93'. Would Logging then sending it to the chipper help? I just dont see as many possibilitys to tunnin 93' compared to 94'+.

[pcmforless]

yeah, datalogging is a nice help if you have access. The dataloging cables are avaiable for arond $40 bucks now and the software is free for 20 trials.

[smoknta]

There is no difference in tuning a 93 and 94 for mail orders. The 93's you get sent a chip. The 94+ you have to send your entire PCM out to the tuner.

[Speed Density]

So alvin when i come to you for my chip, i should send what logging files with the order sheet? idle, wot, dyno, cruise?

[smoknta]

Most of the time you will tell him what you have done to your car and he will send you a base tune. Then from there you can datalog and send him the files and he can tweak the tune from there. I would suggest paying the little extra and getting unlimited reburns.

[z28suka]

you can pay extra and get unlimited reburns?

[James Montigny]

Where would one order one of those cables and that software?

We do $75 "untill the setup is right" Then another $25 when you change the setup.

I'm thinking about doing something small per reburn but haven't made up my mind.. Something like 10 bucks a pop.. The idea woudl be to keep myself motivated when people ask for changes and need retunes..

so does that apply to my car as well? probably not :(

[TransAm93dude]

Ok. I'm new on the fourm but i'v been on njfboa for awhile now. I have a 93 T/A with 150k on it. I have edelbrock shorties, stock y pipe, a gutted cat, 3 in. cat back(unsure of make b/c it was on the car when i bought it.) Some ppl. tell me it might be a mufflex. I also did the throttle body by pass kit,
hypertech 160* thermostat, 3.73 posi, cool air intake, i had to do head gaskets so after checking out the heads my boss had them shaved. I also put in a hurst short throw shifter. Is it worth doing a tune or sending out for a chip? OoO. Suposedly the guy I bought the car from installed a "stage II hypertech comp chip" hopw do i check to see if he really did? Also, My speedo read 10 mph faster than im going, how do i fix that?

[James Montigny]

3.73 gears on a car that had 3.23s stock will cause you to be ~10mph (16%) over at 65mph. On a 93, you can either use an SLP calibration box or have
the gear driving the VSS changed to reflect the new gear ratio. You cannot
change the speedo in the PCM.

Having said that a mail order tune would be a nice upgrade for you.
You can have one done for $150 or so and pick up a few hp.

How much did he shave those heads?

[TransAm93dude]

The thing is its off 10 mph at every speed. Well, its either 8 or 10 mph off. Either way its always the same amount off. I looked it up my car came with 3.42s stock

Not on a 93.

[z28suka]

not even the 6 speeds had 3:42's in 93?

[Fastbird]

Nope. 3.23's or 2.73's.

M28 6 Speeds got the 2.73's. M29 6 Speeds got the 3.23's.

Rumor has it that a few late production run 93's got 3.42's, but it's unconfirmed still.

[James Montigny]

Check your RPO codes :)

Thats wat my car was a late 93. Plus its black, leather int., t tops 6 spd. , i ran the numbers... my car came with 3.42s, but the grs, i blew up were 3.08s. Kinda weird. Any7how it still read 10 mph faster even when the car had the 3.08s in it

[James Montigny]

When the car is sitting at idle, what does the speedo say?
I'm starting to wonder if it's a bent needle or offset gauge faces.

[TransAm93dude]

It rests on the needle thingy blow zero. I replaced the speedo cluster with another 93 T/A cluster and it does the same as the other one. I have stock tires and rims and it does it.

Mine is late production, they feel like 3.42's but we haven't dug into them yet. I'd be surprised if they weren't.

[Fastbird]

It's the gearing in the tranny. Having driven my black car (almost a year ago now) and then driving the purple car with the 3.23's back to back, the black car felt 100% better than the purple car with the 95 T56 and 3.23's.

Welcome back Gearhed......haven't see ya here in a while.

OT: you have been down almost a year?! missed that, sorry to hear it. (sent a pm as to where i've been)

I can't compare the two since the 93' is M6 the 97' is an auto w/stall. I'm still partial to the T56 and probably always will be.

Yeah, it's actually not been 100% for over three years now. Next spring is the reawakening though......:D

[Jeremy]

you can fine tune anything if you know what your doing. I started my tuning skills out on hondas and now am toying wit the f bodies. i have the chip burner and all to do my tuning and flashing

I have read many times that '93 Trans Am's were not available with leather and I have never personally seen one as well w/leather. Has your car been reupholstered from the corduoroy style fabric to leather? 3.08 gears were not stock in your year TA. 2.73 or 3.23 is what came in a '93 unless you have a factory error or something that was done by a drunken installer on a Friday evening at quitting time.:)

[James Montigny]

Importkiller's Yellow 93 TA was leather.
Slightly different setup (specifically the headrest) than my 93 Hawk.

[smoknta]

My 93 came stock with leather. Its not in there anymore, but the seats are sitting in the garage and the back seats are in the attic.

what color?

[93TransAm]

If that is the case then it must be this Pontiac literature I have that made the mistake. It has all the options for a 1993 Trans Am including interior colors, exterior colors with the base, Formula and Trans Am models. Leather is not a listed option. It is the sales literature that was actually in the dealership. Mine came from Jim Mcquade Pontiac Buick when I visited the dealer to try out a Buick Grand National he had on his lot in Spring 1993. I have read on other forums the same, that leather was not an option and I myself personally have never seen a '93 with leather. If it did come with leather then I guess it must be a slip up by Pontiac to print incorrect literature without proof reading it first. Who would have thunk it? :secret:

[smoknta]

Tanish grey, I'm not sure what the actually color was called.

[93_355bird]

My drivers seat is tan leather and has a big tear in it, you lookin to get rod of them?

[smoknta]

Mine has a big tear in it also. But the others are in good shape. I will get rid of them though.
