📢 Best & Worst Tuning Practices | MASS DEBATE

[@haltech]

It's the debate you've all been asking for! We've invited Andy Wyatt (Adaptronic/Haltech), Adam Neish (Just Engine Management) and of course, Scott (aka Tuning Fork) to talk about tuning fails, DOs and DON'T and offer their hints and tips on how to get your car tuned quickly, efficiently and safely. What was your worst or best tuning experience? Let us know in the comments section!

[@dalaw6600]

Haltech needs to partner with a app company to make a Tuning Simulator where you run different cars on dynos and have to go through tuning it to make it run as good as you can and clean up the fuel maps to get a high score think this would help people who are intrested

[@260k1s]

I'd pay for that

[@chromaticwolf7433]

There is a game called automation that seems to be the best we got. You tune the hardware to make more power or more fuel efficiency ect by adjusting intake size, turbo compressor and or turbine size, boost pressure ect. It is a tone of fun and is decently realistic I would highly recommend checking it out. Ever wondered how much power a 4L 4cyl engine would make with a 100mm turbo. Or how much power a 500cc engine on nitromethane with a 15:1 compression ratio and a turbo bigger than the motor could make before grenading. Maybe you dream of hanging a 2000hp iron block drag motor out the back of a smart car with a 1.8m wheel base just to see if you can make it do a back flip on the street. Well, if you have these thoughts and don't feel like sending you and your own car to space (and your wallet) then this game is perfect for you.

From a experienced retired tuner, a tuner REQUIRES a thorough knowledge of the mechanical side of the engine and whole package. - Most useful tip I have for your viewers is NEVER believe that any work (either electrical, mechanical, or tuning) done before you received the car has been done correctly. - Most often faults in cars brought to the dyno would be in this order: low level fuel in tank, wiring issues, fuel pumps, h.t. leads, old plugs. - As for most interesting problem/fault, in my first year of professionally tuning, I had a race car that tuned up great on the dyno with owner very happy but went bad later when checking the tune on the track. After every lap the engine would run richer and with noticeable lower top speed down the straight. After 5 laps and leaning it out 5 times with no reason or problem observed from a engine management point I had to insist to the owner he had a engine problem. I was a young tuner and he was a retired tuner and engine guy from TWR so it was a very big call to make! I was pleased, and have respect for his integrity, when a week later he came back and told me the external oiling system he had built for the cams wasn’t working as expected and the cam lobes were badly worn down! The moral of that story is that if you are sure with your diagnosis and beliefs don’t be afraid to stick with it, if you don’t have confidence to trust your decisions how can you expect your customers to have trust in you.

[@doubl33Ace]

I tuned a 86 with a 4age 20v for customer a few months back and I noticed we were losing power after about the 5th pull, particularly at midrange to top end. The power just kept dropping on subsequent runs. I went through all the sensors, calibration, timing, trigger, etc and everything seemed to be fine. Inspected sparks and performed engine compression test and all was fine as well. Finally, I noticed a lot of metallic particles out of the tailpipe and around the rear of the car. The car had a catalytic converter and the cat had failed and clogged up the exhaust system which caused major exhaust restriction.

[@thymetodream6084]

In regards to catalytic converters, I've seen the insulation blow out from the first honeycomb pack strait into the face of the second, thus causing the restriction and the rattle can symptoms. Another reason for this failure I've seen, besides old age, is if un-combusted fuel enters the exhaust and ignites. I've come to believe that cats don't like explosions!

[@Kaxlon]

100% agreed with all your points, guys. Every beginner/hobby tuner should make a PDF and print out, or atleast keep that PDF on their laptop or phone. But hey, paper don't run out of battery. ;) My personal demand is a AFR meter and a boost gauge, or I will never touch the car, not even "take it for a spin". Greetings from Sweden! =) /Kim. 1991 GVR4.

[@iwanttobeamole]

Fantastic Video. I'm a "home guy" and have built a number of cars in my own (or mates) garage. The biggest question mark has always been the tune, and tuner. I've never had a check list provided by the tuner or for that matter, any direction at all. This is awesome info and great from the other side of the table to help me make sure I'm presenting the car to the tuner in the best state it can be. Thanks guys! P.S. None of my cars have exploded yet!

[@haltech]

"None of my cars exploded yet!" - Love it:) Keep up the good work!

[@harleydaun3847]

You know Scotty, I did a very similar thing with my brother. Working on his na miata we had just put a standalone in, accidentally got a tiny thread of wire in the wideband controller, shorted the microcontroller out and it died. We were also right at the same time checking our base timing. Set it to 10 degress BTDC. Come back 2 weeks later with a new wideband controller. After 20-30 minutes of driving around being really confused why it is so slow and I can smell so much fuel it hits me. That little ignition gauge I'm looking at on my laptop has been on 10 degrees this whole time. Turned off fixed-timing and it was beautiful. We probably spent a good 15 minutes speculating.. Is a valve stuck? Did the crank pulley slip? Is the ignition coil dying?? Nope, just forgot to turn it off before we finished up last time

[@16vg60mikey]

As an aspiring tuner thanks for sharing the hard earned knowledge!

[@rainvillecreative5410]

Glad they mentioned the difficulty of the FSAE cars, I was on a team that ran a single cylinder turbo KTM450 that was a nightmare. It was a smart choice going single cylinder given how small the intake restriction was, since most the teams that run 4 cylinders seem to have trouble with them getting choked out. However there were more inconsistencies- the intake pressure was very cyclic, and even the engine RPM was varying quite a bit every cycle from the valvetrain and compression.

[@Tony-ib2vm]

Displacement is a waste in fsae, everyone doesn't realize there is no minimum weight. Why carry all that engine, if you cannot use it... Look at the vacuum diagram of a tl1000r. There are jets and a canister upstream of the iaps/map sensor, to smooth the pulses.

[@rainvillecreative5410]

@@Tony-ib2vm Our team was one of the lightest tube frame cars, 373 pounds wet I believe thanks to the motor that weighed about 65 pounds. Big intake plenums can help too with smoothing the pressure out, but still a challenge.

[@sirspamalot4014]

Wish I'd joined one of these teams before they went all electric, doesn't have the same appeal to me anymore. Even though I'm studying electrical engineering, ICE is just more interesting to me.

Having done my apprenticeship in Australia and during the time that commodores and falcons were cheap, I know them like the back of my hand, hand me something euro and it's a headache because I actually need to call on my diagnostic knowledge and years of experience rather than just knowing what's probably wrong like I do when a commodore or falcon rolls into the workshop

[@johnsnow5239]

Great video. So many small things we forget to look at. Brings back memories. My first car was a Datsun 1200GX coupe. Turbo charged the original 1200 engine. Toyota 2e pistons. Custom intake plenum and a 4age throttle body. Stock crank and rods. Made 148kw at the wheels. Was a laugh when everyone thought I was running a 4AGE twincam until I opened the bonnet....

[@hoonaticbloggs5402]

Interesting hearing him mention the bike engines with plenum instead of individuals. I’m a bike tech by trade , but have an ls1 with a big cam and went with an itb set up , because I know how bikes use big overlap with no issues

[@jbm3458]

Really good EP!!! your a good bunch of humble men, with a good passion for cars :) exactly what all industries need

[@ianm432]

2j vvti has got me twice on weird issues. One where the engine had been assembled by another shop with the timing marks with the dots vs notches mixed up put the intake cam way out. It actually ran but sounded like a Bridgeport. The other was an engine assembled by another shop that must have dropped the crank trigger wheel. They would have dropped it, looked at it and it was fine. Fast forward to getting that engine running, first crank it was perfect for 30 seconds and then never again. We even pulled the crank sensor and looked dead on at the crank trigger wheel to count the teeth. Looked fine down the sensor hole. Pulled our hair out for a week, missed an event before pulling the front of the engine apart to find a tooth missing.

[@cartruck1070]

I wish politicians would learn to debate like this. Very informative to understand things correctly and to make your correct choices and steps to each choice. Thanks fellas.

[@turbotrana]

My advice is to always use the lambda sensor bolted in the dump pipe or closest to the engine. Never in the tailpipe. I sometimes even use two wide bands to make sure reading right. EMS had a feature that data logged average lambda at the load point that helped heaps. I never used dynos although would of helped in the 500hp+ region with a good load bearing dyno. I don't recommend street tuning either but can do most low and medium points with it, actually better on the road.

[@ECMUnltd]

This was such a good interview! Quick comment on the section of the engines they like to tune the most. It was immediately apparent that they both like the challenge of tuning the same thing. The only difference is scale. If they compare notes I bet they solve each others problems!! Thanks for this one Tuning Fork! I tuned my brain with this!

[@ECMUnltd]

Side comment. Im fairly certain the reason your pumps need more current is simply the way your attempting to pump (suck) up the water. I can easily say its the fluid dynamics that are the problem. If we study Viktor Schaubergers work on water and fluid dynamics. Fluids dont really have resistance, this goes against alot of common beliefs. If you simply change the area that has suction to something that will allow the water to vortex you will immediately find you wont need any electricity and UP your flow.

[@michaelhowatson8832]

I had a clevo that kept retarding timing every time I backed off over 3500 rpm. Turns out the vacuum advance was letting the inner and outer magnetic ring touch and then the inner ring would retard. New drive pin and shaft bush and never missed a beat since

[@Concept5North]

Andy's T-shirt sums it up really well. If you've ever used Adaptronic vs Haltech - Adaptronic is engine management software for a software engineer, Haltech is engine management software for an engine builder or designer.

Absolutely, the more data we have the better the tune will be. If it's possible to get a wideband sensor per cylinder and exhaust gas temperature per cylinder we can essentially tune the engine per cylinder!
