Good morning everyone,

I am looking for information on EBL Flash Tune capabilities. My IROC 5.7 TPI is running the stock injectors (high impedance) and EBL Flash w/ port mod. I have 4 brand new Tomco rotary disk D1680BA low impedance injectors that flow 380cc that I would like to use, (found 4 more for 70 bucks), on my 406 FIRST TPI w/ 195cc AFR Competition heads build.

Can EBL handle low impedance injectors? Any benefits to why or why not?

All information would be appreciated. I am still learning about the EBL and I don't want to annoy Rob for everything. Thank you!

To properly drive 8 low impedance port injectors need the 4-Injector Upgrade. This will allow you to run four low impedance port injectors on each driver (wired in parallel).

There is more info on driving injectors here:

The EBL Flash ECM can handle low impedance port injectors. But in stock form only 2 in parallel on each driver.

P.S. been having email server issues at this time.

 

This 4 injector upgrade...where do I get it...or better yet, how? Is it a software purchase? Hardware purchase?

Thanks!

 

It is a hardware upgrade. Ship the EBL Flash ECM to us for the install. See the EBL Flash product page for ordering it:

Typically we turn these around in a business day.

I see, ok thank you.

Just to clarify, are the low impedance better to use over the high impedance?
I came across 4 more new Tomco low impedance injectors just like the 4 I have had for years. They are new for 70 dollars on ebay. The 4 injector upgrade is 75.00 bringing the cost to $145.00 to invest. I could also buy 8 new 36 pound injectors for just over $300.00 BUT...are they better than low impedance injectors? I am not so sure about the benefits of either with EBL or even my street engine. What do you suggest Rob?

Thank you again!

 

Here is another possibility. They cost more than the low impedance method I wanted to go but cheaper than the Lucas 36 lbs high impedance.

My 406 will be running the FIRST intake and AFR 195 Eliminator heads with a Hyd. Flat Tappet 219 cam @ 112 LSA. Lift will be close to .500".

As much as I want to send my EBL back for the 4 injector upgrade, I found myself wanting to save the trouble and just keep using high impedance injectors. The EBL is working...the less I touch the better!

Low impedance injectors open more quickly then high impedance injectors. This provides more headroom in the duty cycle at high RPM. Not really required on a TPI inducted engine.

More important for a good tune is having the injector compensation values.

Thanks Rob,

I will go ahead and buy a set of 36 lb high impedance injectors from racetronix. The Tomcos can go in my Ford turbocoupe if/when the brown tops go bad.
