I think you might want to reconsider your target AFR table. You have it set up so that your AFR is changing based on RPM only rather than MAP. MAP goes up, AFR should get richer. The top few rows should be your WOT AFR, then a few rows of part throttle, then the remaining your cruise and idle AFR. That's generally speaking. Basically, your AFR should be more Y axis based than X axis based. I don't think you want 12.8:1 at cruise or 14.7:1 at WOT from a dig.

[@QuigzDrifts]

Great video you really explained a lot. Question for you, on your target AFR table, on the wide open throttle at lower RPM why do you have it set to 14.7 instead of 12.5? Even though the RPM is lower wouldn't you still want 12.5 at wide open throttle?

[@KarKamp]

I like watching your stuff an have been for awhile now you kinda helped me with some of the HP Tuners stuff I know but I'm surprised that you are going to Holley.. An I'm curious if it's on your truck because you seem like one of those die hard HP Tuners guys.. Just curious as to why the switch now rather then before.. I thought a tuner was open to using all types of systems.. Keep up the work an I'll keep watching.

[@GoatRopeGarage]

Nope, truck is still factory ecu

[@rodneyharris5606]

Thank you

[@frankrey7676]

I have a term x max on a sbc with a 8-71 blower. The self learn has not met the advertised ease if use. Probably my setup though. I am getting better results just looking at the logs and adjusting the map.

[@GoatRopeGarage]

That has been my experience. I’m not a fan of the Holley self learning. The wideband controllers aren’t very good.

[@Wrensspeedshop]

Had a question about different types of setups. I recently purchased the Terminator X system but have yet to install everything. It’s going in my 99’ TRANS AM. I went ahead and purchased a splitter CAN cable so that rather than only being able to plug in the 3.5” screen to the car/system, I’m able to plug my laptop into one of the leads as well as the 3.5” screen into the other lead. By doing so I’m able to have both plugged into the terminator system at the same time. Have you done this or know anybody that has? If so, do you still have to go through the process of making any tune corrections then uploading them from your computer to the terminator system via the SD card, Or are you able to utilize the direct connection using that splitter cable? I hope that question makes sense. Appreciate the video and all of the information in there. For a beginner like myself, little things like the fuel tables and how to set it up will make a huge difference. Keep the videos coming!

[@Ls1ears]

Maybe you'll see this comment but I've been watching your channel for awhile. I'm currently trying to learn hp tuners, I have the mpvi2 in a 99 trans am. Ls1 nitrous car with a th350 trans, nothing just wild but I've been debating on swapping to the holley terminator x setup for the simplicity of the tuning and ability to control the nitrous and all that which you cant do with hp. What's your opinions on this?

[@unclebishoppeskitchen5838]

If I use one of these on my build will I still pass emission inspection?

[@thomasjohnson1142]

That’s cool I was wondering if it was self learning if it would make corrections on it own so I like the fact if you want to run a little rich you don’t have to apply the changes it makes if I was understanding that correctly?

[@GoatRopeGarage]

You want it to run a bit rich you can host change the commanded table and it will dial it in to that afr

[@thomasjohnson1142]

Goat Rope Garage oh yeah gotcha I remember you saying you can adjust the curve to whatever afr you want cool that makes it a lot easier than oem lol

I’m looking at getting HP tuners and need recommendations on what to buy. Do I need the pro? Going to be using it on my 2000 Camaro. Right now it has SD tune but possibly looking to go back to MAF. it’s a N/A build street/ sometimes road race fun car. And which AEM wideband to go with? Thanks for the help.

[@GoatRopeGarage]

If you use the 30-0300 wideband you don't need the pro, you can use the serial option to get the information into the scanner. It's the most cost effective way.

Log a few decel cycles and lean out that area. Take a note were the engine is at when its on decel. Usually is the mid rpm low map area of the table. Accel/decel and the such are good, but you shouldnt “rely” on them. Your ve needs to be dialed in very close

I have not bought the terminator yet, still on hp tuners... BUT, I did download it just to check it out and I really like it a lot. I wanted to ask though, is there a way to add and subtract fuel from the ve table without manually entering in the numbers and filling row and columns? I like how on hp tuners I can press the +, or - button to add and subtract, and how it is set up to add a certain % of fuel.

Right click and choose offset, you can do it as whole numbers or percentage

[@snail5341]

what determines which afr do you use per cell. Meaning Im pretty sure that I want 14.7 at idle but what about different loads and different rpm's. I guess the simple question is do you have a afr map that you suggest? procharged sbc roughly 700-800 hp on 93

[@GoatRopeGarage]

There is an AFR table that determines that, I touched on it briefly on this video, can command anything you want

[@snail5341]

Goat Rope Garage I understand that. I’m asking what afr do I want? 14.7 idle? 13.0 idle? 10.8 wot at 150 kpa 5500 rpm? I just don’t know what is best Plus I don’t want to blow up my stuff

[@rolandbeliveau8379]

snail5341 under boost, 11.8-11.3 is generally safe depending on what your temps are looking like, 12.5 usually is about the max you want under max “NA” load(max load before boost) and 14.7-14.0 for cruise depending on temps and random conditions. You can actually go kinda lean on idle to save fuel if you want, as the car is under almost no load at idle. You’ll want to blend the cells between these conditions as aggressively as you need to “ramp” the fuel in depending on what you’re asking the car to do.

[@GoatRopeGarage]

Bingo!

Roland Beliveau thanks. That helps a lot

Goat Rope Garage and delete them with hpt lol

[@LS1FREEK]

Why are you not going richer AFR at lower rpm and high intake pressures? Say at 1000-3200 rpm and say 90kpa on up you should have 12.5 afr as well

[@GoatRopeGarage]

Nah, no reason to be that rich that low

[@LS1FREEK]

Also I would turn your decel cutoff off until your base fuel map has been learned, then turn close loop off at 0 throttle as well to keep the ecm from trying to learn when injectors are actually turned off

[@GoatRopeGarage]

@@LS1FREEK closed loop is disabled at 0% throttle, so dfco isn't being taken into account

[@LS1FREEK]

Being a tuner for 14 years, I can tell you from experience (60ft at the track, and butt dyno lol) running a richer AFR like 11.8 or even 11.5, and pretty high timing (around 32, but that depends on combo of course) below 3400 rpm will make more power on most LS based engines. Stock gen 3 GM tunes usually have them leaned up a bit down there for better overall fuel economy, but time and again, most every customer of mine claims better launches when I setup more PE AFR down low (stock converters of course).

[@GoatRopeGarage]
