This really helped. i had no idea what I was doing until i watched this

[@TurbineResearch]

That’s what it’s all about! Glad the videos helped

[@StefernOKioni]

We can LEAN on the side of caution and make our tune RICH! English fought with science again!!

We really do appreciate it! Your videos are second to none!

[@TurbineResearch]

Thank you ! I’m glad they are helpful

[@ihulk1]

Thank you for your videos I watched the one about warmup enrichment and got it idling perfect. But can't seem to get the after warm-up right and it stalls on its face unless I apply a little pedal and it idles up and afrs are 14.5/14.7 and once I let off the gas at idle it stalls. I have an 02 NB2 1.8 vvt with a speedyefi ecu stock 265cc injectors.

Great tutorial. Makes life a lot easier

[@TeamHenryhand]

Thanks!! You make it look easy. Keep up with the great content. We appreciate it.

[@Suicid3mx3]

thanks dude! comment on every video you watch!

Holy afr tuning batman!! 😳 give me the beans!! Love the video!! Way to good 👍 👌

[@tracnunya7165]

excellent intro to the theory and the software

[@EricEgot]

I've got a 2017 LANCER ES and this helped me look at my FUEL Table much more efficiently!! my stock rom shows from 5000RPM - 7000rpm & 60& - 100% load It goes as rich as 11.0 closer to 100% load.. I changed mine from to all 12.5 and put 85% to 100% load at 12.2 from 6000rpm to 7000rpm I'm not sure how MIVEC works completely but I know it starts within 3500 - 6200rpm

[@giovanniperrone1044]

love your megasquirt videos! keep up the great work 🍻

[@TurbineResearch]

Thank you !

[@MeegNumber2]

So from here. What do you do next? Like I’m the dyno what do you change, how do you know which numbers to change.

[@GRUDGEPERFORMANCE]

You will adjust fuel cells to the correction % the ecu is adjusting, say the cell at 1500rpm on 60.0 is being corrected by +- 2.7% to get to the target afr as shown here, you adjust that fuel cell by that amount until there is no correction, do this to all cells and you will have a very nice fuel tune, then playing with timing on top of this

[@boostv8chevy457]

Hi. yjank you for the video. i like to ask you if you know the funtion of the ambient temp sensor.. One mpre question. I have a LS1 maf. tp put with my 4 cilinder 8psi volvo. i see no one knows about this two questions. i have my volvo siiting for more then a year now. i like to learn atleast the basic tuning and move the car from point A to B

[@Grainsauce]

Love your easy and knowledgeable videos, I have a question in "General settings" the "Incorporate AFRTarget" is that good to leave off while tuning or leave it on, I've heard you should leave it on otherwise if you change afr's you would potentially have to change your VE table also, just wondered if you use or know more on that setting.

Where the links bro not in description

[@memestroll2143]

I have a 89 Fox I just bought. Has been turned in FL. I'm in TN. On3 and many extras. Ran a AFR of 11.0 at one point of high rpm. Thoughts!

[@TurbineResearch]

If you’re turbo 11afr sound fine

[@ozziintheuk-5105]

Excellent!! Please keep making these Megasquirt video's. And if your looking for some subjects to cover, can you explain the purpose of the VE table?

[@TurbineResearch]

Thank you !!! The quick answer for the VE table is that it's used to calculate the required fuel based on the volume of air ingested into the engine as a percentage out of 100. It's the fuel table to map how much fuel to inject at any given load of the engine.

[@alexandruvoda2290]

Nice 👍 Have you thought to do a video on a vvt table ?

[@johnnydanger57]

I have been fighting to get the AFR table to control the AFR ratio correctly. All your videos have been massively helpful! I have done the best I can to give the Megasquirt the correct information from my Innovate MTX-L plus, even going to custom mode with voltage values. I have had the motor dyno tuned, also used tuner studio to set fuel values. I have the "use AFR table" set to on. Still the AFR is not even close to the table, and I literally destroyed 3 pistons from detonation as the Megasquirt is not following the AFR table. I'm not sure what I did wrong. (or the dyno tuner) Advise would be greatly appreciated! (I have contacted Megasquirt, with no reply, and asked on their tech page, but only got vague responses) (1994 Mustang Cobra 363 ON3 turbo)

[@TurbineResearch]

There is a lot that could potentially be wrong with how things are setup. You might need to have someone tune the car that specializes in MegaSquirt products.

[@johnnydanger57]

@TurbineResearch that's actually what I did. The dyno guy said he had been working with megasquirt systems for almost 2 decades. He changed the tune a bunch, but the data log was still not following the afr table. I tried again to find which of your videos showed the full set up on getting the afr table to control the fueling. But you have so many it's hard to find the exact one. Thanks for the reply!

[@h3atn3n]

@@johnnydanger57 did you find out what was causing your issue I'm having the same issue I have a Miata but I have a speedy efi and I change the afr table but it doesn't change I also tried to adjust the duty% and the amount of time the injectors are open by like 2 MS to see if it changed it didn't at all

[@johnnydanger57]

@h3atn3n83 I found out the afr table is pretty much useless as an adjustment table. They are just calling it a reference table, whatever use that is. It's your fuel table that needs to be adjusted to get the correct afr.

[@Elturko1982]

Thanks ❤

[@adik9441]

Great video

[@gtfm50]

So I have a question. Does the mega squirt go by the AFR table or the fuel table. Or is it the mega log viewer compare the AFR table and change the Ve table? Cuz I'm having a strange issue where it was running great at like full throttle it would be more rich but now after the car was sitting for a while if I get on it it gets really lean like around 17 to 19 ish and now I'm afraid to drive it!

[@hmsRoo]

Amazing thanks for making this

[@racerd9669]

Awesome job.

[@s1xer_]

Thanks man

[@Suicid3mx3]

Could I use this table for e85? And not coming vert everything to lamda. I don't really understand lamda

[@TurbineResearch]

Yes you can use this for e85 as long as your wideband is on the gas scale and calibrated in tuner studio

Hello.Do you not know what data to enter when setting up the bmw vanos on the m52tu or m54?

Good work

Very useful, thank you!

[@H-M-78]

Any differences on a 1000cc turbo motorcycle AFR table?

[@TurbineResearch]

You want to use a dyno to be safe but this table will be a good safe starting pint. A turbo 1000 must be nice !

[@H-M-78]

@TurbineResearch I actually have a 1300cc with turbo kit. (Hayabusa gen1) The stock fuel injection is untouched and using extra injectors in the plenum. It's running a little bit too rich so I started try using Tunerstudio recently

[@TurbineResearch]

@@H-M-78 that’s awesome 😎 nothing in my mind is as wild as a turbo hyabusa

[@H-M-78]

@TurbineResearch yes, its pretty fast for streetuse, about 300 hp to the wheel. Only using a spacer too lower the compression and some harder clutch springs, that's all. Question: when using autotune there's a checkbox "update controller" Does "checked" means that the corrections running in real time?

[@TurbineResearch]

@@H-M-78 do you have an instagram or KZbin with videos of the bike ?

[@brendanmccabe8769]

Nice video, good clear explanation but is it really necessary to have that background “music”, It adds nothing and is distracting? You’re not alone of course, it seems like no YT video is complete without.

[@TurbineResearch]

I quit adding music for that reason
