Hey everyone. Trying to make this to the point. I've done advanced HP Tuners tuning on my Gen6 LTG 2T. But this 93 style system has me a little searching for clues, I've been around the suggested tuner resources mentioned on here, but in fairness, each year of the LT1 has too many variables to wrap my head around for getting to step 1 for my 93, built late in 92 btw.

Have a new 2 me 93 Coupe AT with 50K miles. In very good shape. Coming from a M6, first gear on this 4l60 goes from zero to infinity and I am thinking some remapping and tuning will help with some of that mid range straight line performance. Maybe look into a diff re-gear.

I've poked around the ECU in the engine bay and I think I see the trap door where mentioned chips and mounting adapter would live on the bottom of it. Is this the place? I would like to work with someone who can walk me through the exact steps for MY 1993 Lt1 AT Coupe. If a chip could be good for helping "premium" gas which is really 93 E10 now, if AT shift points may be improved, etc. Just getting it optimal would be good.

I would be very grateful to be pointed in the right direction and not have to chase down the right tuner at 5 shops who may do the 93 LT1 or not. Who exactly can do this specific car? I just need to go through the motions and then I will be able to understand and probably get my own burner kit and take it from there after some basic orientation.

Thank you very much.
George

 

I have a 93 also.

Removable chips are outdated.

you need a moates ostrich with a piggyback socket for the chip.

you can then plug a usb cable into it and tune on your computer yourself using tunercat (to tune via that usb socket on the moates)

and you want datacat (to datalog via the aldl port). You will also need a special cable to datalog - many are junk out there.

i recommend buying tunercat and datacat- the software is well supported for those who tune

the definition files for the speed density 92-93 are referred to as $da2. You will need that definition file loaded into tunercat to read your tune in tunercat

tuning speed density is simple. When datalogging you can see the changes you have made to the tune and how the affect fuel trim histogram tables and knock retard activity.

 

93 tranny is non-electronic so you can't change the shift points by the computer.

 

What fredk said--you'll need an old school shift kit to adjust the shifts on your 4I60. Trans Go comes highly recommended around here, but it's not as easy an install as the B&M.

Thanks guys.. My new 2 me FSM books should be showing up this week. Will self educate as much as possible. I found a fresh tank of 93 really improved launch and saw ASR flash there for a moment. I bought Moates entire suite of tuner chip things. Hopefully in the future I can offer any techniques and how 2s for others. There probably not a hell of a lot to improve but it will be good to know I can optimize to what ever comes along. I just noticed my tires are 02 and 04, so gotta work the budget for this survivor's neglected maintenance issues.

 

I blew out a tire dated '99' in 2009 during a downshift and hard accel - after I installed supercharger.

It was a goodyear eagle f1 tire.

The sidewalls detached from the tread. Luckily I got it pulled over and wasnt yet going superfast.

What was annoying was it was a golf course and C5's owners were showing up for their tee times (and laughing at my situation)

 

LOL Right? you cant take anything for granted on a stored vette. My steering is doing the death wobble. like wft. I never looked up date codes on a tire before I looked and noticed suspicious fissures near the rim. then it was an easy goggle XX02 and XX04 on these Good Years. Too bad they have a lot of tread left I have a set of staggered Conti's and B8's in the check out que at tire rack. Will spy around for deals for black Friday. I know this started out as a Chip tuning thread, but conversation is fine with me, Thanks for responding. They should have made more specific forum threads like user build pages and specific engine series.

 

dont trust a goodyear tire

 

This, this, all of this. I have an Ostrich myself and can confirm, it's the way to go for any chip-based ECU/ECM that doesn't have nice aftermarket support (or that you don't want to pony up big bucks for said support to get). Though personally I wouldn't leave it in there the whole time. I know they say you can and it'll work, but once I get the tuning done, I prefer to burn a chip and slap that in so I can seal up the ECM (and reuse the Ostrich on another car!).

But yeah, the post here pretty much nails everything you need to know. If you want to get some specific help, I highly suggest you join the forum "Gearhead-EFI," there's a section devoted to GM EFI tuning with lots of really smart awesome people willing to help.

 

ive had mine in there 11 years / no issues

tthough i have a backup chip(in my glovebox, and tools to replace it) in case it fails somehow

 

Thanks for that. I just need to take the verbal text info and turn it into actual hand motions to really understand it. Moates has a section dedicated to the 92-93 so once I get the computer drivers sorted and logging working, then pick up a wideband and practice for a while. Its how I started with my 18 turbo LTG. loaded bigger turbo, Meth water injection, flex fuel adapter, pipes the whole bolt up thing and HP Tuners logging 400 HP on a turbo 4 cylinder running 13.2 @106 in the quarter mile. These 2T camaros will out run Gen 5s easily and Gen 6s with the modern LT1 who can't seem to launch. This chips thing with $masks and bin files and all that is all new to me. I'm a computer guy so I will eventually figure it out. Its probably a good reliable system from what I am reading and I have all winter to learn up with help from the community. I have been reading a lot on here so your pointers are very much appreciated.
