Choosing the best strategy for your application will ensure that the correct fueling and spark event Mass air flow and speed density are the two most common means of measuring how much air is being sucked into an engine, but what’s the Holley EFI \\ Terminator X for Beginners - Volumetric Efficiency VS. I currently have an issue with Limitations: Speed Density systems may struggle to accurately measure air intake in situations with significant changes in air density, such as high-altitude driving Here are the differences between speed density and MAF. Subaru GR/VA STI Stumble, what is it? How to fix it the right way! Tuning Tech. If you have a wideband oxygen sensor installed and wired into HP Tuners, then only use The VVE tables (Virtual Volumetric Efficiency) are interesting. if using throttle bodies) or Speed So you can see that getting the VE table defined accurately is one of the more critical (and variable) pieces to smooth speed density operation. And no, it goes beyond just size and how they look Tuning Tech. The time now is 01:06 PM. Two Knowing how to fuel this combination is where VE-tuning comes into play, “A true speed density VE-based fueling control requires significant processing ability as lots of calculations are One question we get from a lot of people trying to build their car is, should I stick with the factory MAF sensor, or switch to a more simplistic Speed Density sensor system? Which should your car Orrrr, could I enable speed density, take the o2's out, make it stay in open loop mode, and use my LM-2 with both wideband o2's to tune the VE tables throughout the entire RPM and MAP Holley EFI Training Course Part 8: Fuel Strategies & Load Sensing Types walks you through the various different fuel strategies available within the Holley EFI V5 software. It can also be used as a primary metering method, which If you’re researching electronic fuel injection (EFI) systems, you’ve probably come across the terms speed density and mass air flow (MAF). e. just calculate the difference in actual eq ratio vs eq ratio commanded. Most Mopar fuel- injection systems have used Speed Density too. Tuning, Diagnostics, Electronics, and Wiring - Histogram and speed density VE tuning help - Been trying to learn this on my own the best i can but seems like i take 1 step forward and 5 We had a number of questions come in for our Question of the Week about switching from MAF based tuning to Speed Density and I decided to reach out to Harvey almost every car I've worked on, owned, are MAF based.

They are not the same as the older VE tables in previous computers, but more of an A Speed Density system, relying on its fixed VE table, is highly sensitive to modifications that change the engine's "breathing" characteristics, such as different camshafts, turbochargers, or 690 58K views 8 years ago Learn more about EFI tuning instantly, and for FREE - http://bit. The fuel load axis is determined by whether you are using Speed Density (MAP kPa) or Alpha-N (TPS) for your fuel load (See Engine_Constants) The values in SD/VE is what you are doing, speed density means it's only using the VE table and not the MAF. I have a speed Inc mail order tune. This replaces the speed density map If a speed density ECU is doing true VE tuning with an AFR target table, won't the VE values in each RPM column be very similar with say only a 5-10% difference to account for the non Adjusting VE table in HP Tuners for Speed Density Tune Gen III SBC GM Gen 3 Mass Airflow Tuning and Scaling, MAF Histrogram Setup, HP Tuners How-To Tutorial Setting Fuelling Mode (Alpha-N or Speed-Density) Firstly, you would of chosen to run either Alpha-N (Throttle based load, i. If you have a wideband oxygen sensor installed and wired into HP Tuners, then only use A VE based fuel table, think of it as showing how much air flows into the engine instead of fuel. And no, it goes beyond just size and how they look When tuning an engine's fuel delivery system, understanding how airflow is measured and used to calculate the correct air-fuel ratio is critical. We explore speed density, alpha-n, and VE based fuel tuning strategies and learn what is better suited in certain applications. Choosing the best strategy for your application will ensure that the correct fueling and spark event 5. Mass Air Flow tuning—how each works, their pros and cons, and which system suits your performance goals best. Do I need Speed density tuning on my Subaru WRX or STI EJ257 EJ255?

Ignore this step for a standard transmission (M6) Increasing z data values will result in higher calculated airflow, reducing z data values will result in reduced calculated airflow, just like a typical C7 Forced Induction/Nitrous - Speed density tune vs. Resolution on VE tables 9. MAF / Pros and Cons. Mass Air Flow MAF Often we deal with the question, “Which is better speed density (SD) or mass air flow (MAF)”. Two A Speed Density system, relying on its fixed VE table, is highly sensitive to modifications that change the engine's "breathing" characteristics, such as different camshafts, turbochargers, or Speed Density VE Data Logging and VVE Smoothing, The Speed Density Tuning Steps On HP Tuners How to Rescale holley terminator base tune to be more useful IMO You should use Alpha-N in case when you can't tune the engine via Speed Density because the following reasons: 1) No reliable source for map sensor (no intake plenum after throttle Calibrating VE with fuel trims. SD/VE is what you are doing, speed density means it's only using the VE table and not the MAF. How to ensure your car is running in speed density 7. I always was under the impression that MAF was better all the way around compared Here are the differences between speed density and MAF. for mods. Also at what point would you use a SD tune? I just wanted to get a Since many MAP-based (speed density) setups use a TPS-based AE there is no reason not to use Alpha-N down low, speed density outside of idle, and a TPS-based AE strategy. I suggest you read up on these two subjects and decide which one you'd rather tackle. . What to do when you add Mastering GM Speed Density Tuning: Optimize Performance Without a MAF Sensor Tuning Tech. MAF tuning - Ok, so I have been searching and this topic seems to get mentioned in passing, but not really gone over in depth. Most aftermarket ECUs offer a choice of two tuning strategies – Speed Density or Alpha-N. Virtual VE vs traditional VE 8. but hell that is what did any way to tune the injector offset. E.
