LT1 Tuning 93 OBD1 Tutorial

[@wileygeorge2770]

Very good descriptions of processes and your 16 years experience shows sir. Thanks!

[@Noeysuarez]

Thank you, I appreciate your comment!!

[@cski68]

Great advice in here for beginners like me. Just bought an Ostrich 2.0 for my 88 Callaway Corvette and have never tuned before. The O2 trick will be the first thing I try this weekend. Data logged with TP RT and my BLM's were pinged at 160 and a really stinky idle. Hopping I can solve that with the Ostrich and TunerPro.

[@Noeysuarez]

Thank you for the support!! If you can't figure it out let me know and I'll see if I can help you get it going!

[@maldo72]

good stuff .. ... you should also do some dyno tune of car vids when you can

[@Noeysuarez]

That's a good idea!

[@marcuselias4243]

Thanks for the video! Please keep them coming, I'm new to tuning and have plenty to learn. What is the main difference between tunerpro and tunerpro rt?

[@Noeysuarez]

Thank you for your comment, I will be posting more videos! The difference between the two is that the RT has the ability to do real time tuning

[@danielbryson2928]

i have a 95 lt1 obd1 z28 and i have all the cables to rip and write tunes and tuner pro rt for the actual tuning but im having super trouble dial it in my afr is all over the place i just broke the new engine in with the first 50 miles now im about to run it for 500 miles i would like to learn how to tune myself or r u willing to help tune my bin ill pay of course ...ive found your videos the best on my car so i trust your skills and knowlage

Hey man great video. I know this is an old video but I have a 96 lt1 Camaro putting a cc503 cam and headers. Not familiar with tuning what is the best tuning option for a 96

[@GuessWho785]

Thank you so much for making this video man. I am new to tuning, haven’t got my feet wet yet so to speak. I learned a lot from your video. I have a couple questions: 1- how do you know what your air fuel ratio is, how do I find it? 2- When changing cell values for VE or spark is it possible to highlight the whole table and make changes all at once? Or does not every cell need changed? 3- when changing the VE table what values are too rich and too lean? 4- last question, when changing spark if I wanted to bump up the timing how would I go about that? cell by cell one at a time until spark knock and then retard it by 2 degrees until it stops? Thank you very much sir. I hope to hear from you.

[@Noeysuarez]

Hey sorry I'm just now getting back to you, to know your AFR you'll have to have a wideband o2 sensor installed in your car, you can definitely highlight the whole table to make changes, the answer to your 3rd question is, anything above 15 AFR is lean, and assuming your car is naturally aspirated, anything below 12 is too rich. Just highlight the cells that you want to change the timing on, I'm assuming you're wanting to do the WOT add until you see knock and then back it up like you said 2 to 4 degrees.

[@joeg2727]

Thank you so much for doin this. Subscribed. When you forced open loop, did you leave open loop % to change tables stock? Then just adjust everything in the VE tables? Thanks so much!

[@Noeysuarez]

Yes leave the open loop percentage alone unless you run out of fuel in the VE table, if that happens all you have to do is change the percentage in open loop and that'll give you more room

[@Noeysuarez]

You're welcome, I'm so glad I can help out!

[@joeg2727]

@@Noeysuarez Just wanted to say thanks again, finally getting my tune working better.

[@Noeysuarez]

@@joeg2727 no problem! If you get stuck with anything please let me know

[@jasonkepic1132]

So much to learn and I'm very grateful for your time explaining all of this. I have a stock 93 Vette and I'm curious how much hp gain can be expected by just tuning and also what bolt ons are the most complimentary to tuning? Again thank you

[@Noeysuarez]

Very sorry for the late response, I like doing 1.6 roller rockers and then tuning the air fuel mixture, once that's done, I begin to add timing to the tables 2 degrees at a time until i see knock, and back it off 3 degrees.

Hey Brother....very good tutorial......If you don't mind me asking what tuner software do you think is better? Tunercats or TunerPro? I watched one of your other videos and you were using Tunercats...it looked a little more complicated to me.

[@Noeysuarez]

Tunercat seems to be more user friendly in my opinion

[@horacejohnson7193]

I'm using tuner cats and I was wondering when messing with fueling do you have to mess with the coolant temp % change?

[@Noeysuarez]

If you leave your tune in open loop, you can change that table to help you achieve the afr you want depending on coolant temp

[@PrDeathProof85]

Need more tuner cat videos

[@Noeysuarez]

Really? No one really had asked me for more videos so I haven't made any, but I'll start making more

[@mikemendez9117]

I have a 1994 Camaro with a 383 stroker engine and I just installed a 150 shot of nitrous. But every time I use it the engine starts knocking past first gear. I’m going to buy a tuner and try to tune it myself. Can you tell me where to start and what numbers to change once I get it. Thanks.

[@Noeysuarez]

Yes that's no problem

[@Noeysuarez]

Did you ever figure it out?

[@eliudsilva125]

Buen día disculpa tengo un Corvette 92 y compré el brums 2 de moates le quiero mover alas tablas de gasolina pero en el tunerpro no me sale la tabla de gasolina me podrás ayudar

[@Noeysuarez]

Si claro, tal vez no tienes el xdf correcto, la mesa de gasolina de llama "MAIN VE TABLE" si no lo encuentras, necesitas otra

[@mubashircheentavida]

Going to watch your first video after this one but how should I get started on this one: I'm swapping a t56 into an 94 impala SS. 1. Get the bin from the PCM via eehack or find a stock bin for the car 2. Edit the bin for the t56 settings 3. Load it up again into the PCM LOL does those series of steps sound right to you? I'd like to get another PCM but not sure if a different vin number will mess things up if I connect it to the car.

[@Noeysuarez]

You can edit your existing file to make it a t56, but if you don't know what all you have to change then yes, you'll need a stock t56 file, you can always change the VIN number to yours on any computer

How do you go about idle tuning? I just got my cam installed it seems to die when it’s warm and I push the clutch in just coasting. I have not turned closed loop off would that do it?

What size cam? Look at your idle tables and set them to 750 or 800, also your closed throttle timing, go up another 6 degrees, that should get you going

When you change the injector flow rate do you need to change the injector offset???
