I used a gentleman some time ago and he has since retired.
Who can do tuning now? No I don't want to learn, i want to send my chip out and have it come back 'ready to go'

Is there anyone doing this anymore, or is the 0411 swap the way to go in today's world?

thank you

 

I think efi connection is doing 411 programming. Depends on what your looking to have done I might be able to help if $8d mask.

 

i have a 91 tpi GTA
I need tuned
is anyone tuning the old chips, or is the 0411 conversion the only way to go for now and future usage

 

What have you done to the car that needs retuning?

 

Its 2022, learn to tune if you want to modify a fuel injected vehicle.

 

*an early fuel injected vehicle lol. Or go buy something newer, or install a new commonly supported efi system

sad to say thats really the only options if you cant find someone local. And imo and experience mail order tunes just dont work properly. Really hit or miss.

 

ANY fuel injected vehicle. Easier to be able to tune it than spend $$$$ for someone to half tune it. Seen many high $$$$ dyno tunes that run ok at WOT but have major driveability issues.

 

That's because unless you drive the car around yourself and datalog and get the seat of the pants feel of part throttle driveability, you're not going to get the best calibration you can get. It's all the more important for the older ECM's that don't have the self-learn capability I'd imagine.

 

Any tune shop worth its weight should be dyno tuning and street driving tuning. Thats how we do it. Need the car for a couple days to get cold starts, drivability, etc down. Wot is usually done in couple pulls. It aint hard. The driver manners can be

 

Hmm, go to a 3rd gen site and ask who does tuning on 3rd gen PROMs and get treated like a dipshit.
Thanks fuqrs.

Now, back to the original post, IS there anyone doing actual 3rd gen tuning anymore. OR is it all up to you to get ancient technology and learn to program PROMs like they did back int he 1700s?

 

cam,heads,383, exhaust

 

What cam did you use?

I'm not sure about local guys since I'm not in your area... but if the cam isn't that radical, and you kept the TPI manifold, the tune would probably be very straightforward.

 

try tuned performance here. Thats about it that I know of. You unfortunately are better off learning yourself or looking for someone local

 

keep in mind though, without a WB O2 and ability to datalog, you won't really know what your power enrichment and open loop fueling is really doing with tuning remotely.

that's one of benefits of a local shop that has access to a chassis dyno and the ability to measure actual AFR.

With "mail order tuning" the more information you can feed back to the tuner about how the car is responding, the better the odds. Given the time/money/effort into swapping in a 383, I'd probably at least invest in a WB O2. You can also go so far as to feed that O2 data back into the ECM such that it can be reported out in a datalog via Tunerpro, but that's not a trivial effort to get that set up.

At least seeing the WB O2 sensor in real time and being able to report back to the tuner if you're seeing AFR's in the 12:1 range or 14:1 range or that level of fidelity would definitely be far better than flying blind.

Edit... I just looked at your build thread. Looks like you maintained the TPI, so that's good for the tune simplicity. Just couldn't find info on your cam.

 

I've tuned a couple of EFI Connections 24x 0411 swapped cars. A TPI setup and a Gen II LT1. The ability to log and tune these setups using modern and real time software (HP Tuners) is LIGHT YEARS ahead of how it used to be. I've never done chip tuning myself but I've seen how its done and its a royal PITA. Also, the engines seem to run a lot better.

Buddy of mine has a 88 IROC. 383, AFR heads, 10.5:1 or 11:1 compression, cant remember the cam but it was in the 230 @ .050 range. 6 speed stick car. He had it tuned YEARS ago (chip). The car NEVER ran right. He was about do an LS swap (which I was all for honestly) but I told him to try the EFI Connections 24x swap. He did and the car runs the best its ever had. He did the 383 over 10 years ago. Now he ACTUALLY DRIVES IT! LOl!. Another buddy has a 96 Z28. 383, LE heads, cam, 4L60E, 4.11 gears, stall, blah blah blah. . After several LT1 Edit tunes and tuners, he swapped to an 0411 24x setup. Needless to say, after I tuned it, he loves it.

Make the swap. You wont regret it. Good luck finding someone who still tinkers with chips. That is truly a lost art.

 

I had never heard of the EFI Connections parts before. Looks interesting.

 

I still realtime tune the OBD1s. Works well. I will agree the 24x stuff or even the 0411 van stuff is nice but not needed. My 97 Express with a L31 based 383 runs on a P59 LS controller using the 4x reluctor and factory vortec HVS ignition system like they did in Mexico in the 2005ish GMT800 L31 trucks.

This was the first startup using a tune modified to delete the VATS, added a little timing, a little bump in idle speed and base idle air flow, a Lingenfelter 4" MAF flow calibration and the injector flow modified for the 48 lb/hr spider.

I'm reality, for a 30 year old ECM, the 7730 with 8D has a lot of fidelity on tuning parameters to play around with.

 

yes sir thats what ill be doing.
I have a built engine, and the dampener is too thick to use the EFI/vortec timing cover, so most likely going to use a msd wheel on the damper and the vortec distributor.
ill post up when i get it together..

thanks
