Can You tune an EFI system on a chassis dyno?
Tuning EFI Systems on a Chassis Dyno Sometimes when you are tuning an engine that is already in a vehicle on a chassis dyno, a lot of strange things can happen that you should be aware of. First of all, it is important to keep a perspective on all the things that are happening.
Can a GM small cap HEI control ignition timing?
That is why it cannot control ignition timing using the the GM Small Cap HEI or Ford TFI ignition. It can, however, be used to control the timing on a fixed-advance distributor provided that the rotor phasing is correctly advanced.
Can You Tune Ignition timing on a dyno?
Tuning Ignition Timing Tables Whether you are tuning an engine on an engine dyno or a chassis dyno, you should always make sure that it gets tuned to the proper amount of ignition timing. The best way to do this is to use a steady state holding pattern on the dyno and hold the engine to a specific RPM.
How much horsepower does an ETEC 800 billet head have?
Our Mountain Series PRO-COOL etec 800 billet head is an easy way to crank up some serious horsepower for your Summit or Freeride. Get back a lot of the horsepower you loose when you go up in altitude. Our head is designed to run on premium pump gas above 4000 feet of altitude. Bolt on and easy 6-8 horsepower over stock.
How to synchronize timing advance on Holley EFI?
Adjust the “Inductive Delay” setting to synchronize the timing advance when the engine is revved to higher RPM (momentary 4000 RPM is fine). To change the “Inductive Delay”, the EFI software can’t be in “Online” mode. Turn the engine off, adjust the value, “Save” the change, turn the key on and “Send To ECU”.
When did the E7TE cylinder heads come out?
E7TE cylinder heads came equipped on all 5.0L Foxbody Mustangs between the years of 1987-1993.
Which is the correct firing order for a Holley EFI?
1st cylinder, in firing order, should fire at 0° (or 15° – add whatever your cranking timing is) 2nd cylinder, in firing order, should fire at 270° (or 285° – cranking timing added) 3rd cylinder, in firing order, should fire at 180° (or 195° – cranking timing added)
What are the benefits of aftermarket cylinder heads?
The aftermarket offers astonishing improvements over stock heads, for both f orced induction and naturally aspirated applications. Some well known names are Edelbrock, Trickflow, and of course Ford’s own performance branch, Ford Racing. Benefits from these aftermarket heads are simple – better design, lighter weight, more power!
How does the EFI race tuner control the AFR?
Unlike wide-band sensors which can measure and control over a wide AFR range (10-20), switching sensors can only control within a narrow range (+/- 0.5 AFR). This offset in control is accomplished with the EFI Race Tuner by adjusting the Closed-Loop Bias table. Closed-loop operation is only used when the engine is in a normal operating condition.
What’s the most interesting thing about Efi tuning?
What’s been most interesting about EFI (electronic fuel injection) tuning over the past four decades is how it has evolved from humble electromechanical black boxes, with a Medusa-worthy tangle of vacuum lines, to the modern supercomputer arrays we know today.
Can a screamin’eagle EFI Tuner be used?
Use of this Screamin’ Eagle EFI Tuner system may reduce or void the Limited Warranty Coverage. This Screamin’ Eagle EFI Tuner system allows the engine to reach optimum RPM. It is extremely important that the rider use the tachometer to avoid harmful RPM’s and possible engine damage.

Are there any problems with the raceme tuner?
Problem 1: Depending from what source you have ordered your tuner you possibly have to do an update before you start programming. Only tuners coming directly from us ( racemeofficial.com) have latest updates on it, others from Dealers have been months on its way, laying a long time on their shelves and coming with old software to you.
What to watch out for when tuning an engine?
One thing to watch out for when tuning an engine using a modern fuel injection system is false information from an oxygen sensor when an engine misfires. When an ignition event fails to happen, or the engine “misfires”, the oxygen sensor will want to read a leaner mixture than what really exists.
Which is responsible for idle quality in an EFI?
In other words, the Base Fuel Table is responsible for idle quality, and the self-tuning is responsible for WBO2 compensation. So the idle area of the Base Fuel Table needs to be blended smooth (using the Fuel Graph) to promote a smooth idle, for the same aforementioned reasons.
