Ignition issue with PCV-PTI

Installed my brand new PCV-PTI tonight in preparation for a custom turbo kit idea I have brewing in my mind. Super stoked to have fuel by boost, and timing control. I also installed a set of forged drop in Pistons from RK-Tek today.

However...

After I hooked everything up, primed the fuel system, and pulled the sled over a few times, there was plenty of fuel, plenty of compression, but no spark.

I rechecked my connections at the coils. Everything was hooked up correctly.

Green and white to PTO

Blue and white to the Mag

Dummy plugs to white wires...

So I unplugged the PCV coil harness from the coils, and plugged the stock harness back in. Pulled the sled over, and it lit off first pull.

So figured I screwed something up plugging the PCV ignition harness in the first go round (I didn't), and plugged everything back in step by step IAW the installation instructions.

Again...

No spark...

What gives? Am I missing something? Did I get a bum box?

The fuel side of the box is working just fine, I can dial in the A/F ratios I want, but the box does not light off the coils. : (

WTF MATE!?!

He has a PM in his inbox.

Thanks!

I'll take a look!

The pins are all there.

The indicator light comes on.

The power commander works to control fuel. However there is no spark if the PCV is plugged into the coils/harness.

As soon as I hook the stock coils back up it pulls over first pull.

On the bright side, my fuel map is dialed now. Sled pulls like a champ.

Very easy to tune. I used the Autotune feature, and then manually smoothed, and integrated the trims into the fuel map from there. I have been tuning fuel injection systems for around 13 years.

I don't have an Android device. That would have been nice though. I ride then make adjustments at the house based on the trims from the Autotune. I have some big powder fields within a mile of home.

If you wanted bigger injectors, you could run some higher flowing shorty EV1 connector injectors in place of the stock injectors, and pull fuel as appropriate based on percentage of stock sized injectors/new sized injectors with the PCV.

Since you can pull -100% fuel, you could in theory run a 100% larger injector with very little affect on how the sled runs. In theory of course. You can run into minimum injector pulse issues which can result in a poor idle if a large injector can not open long enough to inject the required amount of fuel to maintain stock idle speed.

If you needed secondary injectors, there are a variety of companies that make piggy back injector drivers for universal applications fairly inexpensively.

First and foremost, a big thank you for the response.

I've been pulling my hair out all weekend.

I downloaded the firmware update from the power commander website. The first thing I do is download and update firmware before I install a new fuel controller on any of my projects.

I'd love to get my hands on the most up to date firmware and give it a go.

A very big thank you.

I got the email with the update. Thanks for the fast support gentlemen.

I'll report back with my findings.

Updated the firmware to 0.1.14.2


Lit right off second pull! Thanks a million gents.


Now that I have fuel and timing under control time to order the parts so I can start welding up my turbo kit..


Wooo!!

Big two thumbs up for for all the guys at Dynojet for helping me resolve this issue within one business day.

I really appreciate your proactive approach. Your customer service is unparalleled in the aftermarket fuel injection industry. I am used to waiting days, and even weeks to get an issue resolved.

I have dealt with many companies who just kind of blow you off, and product reps who do not know their products very well and tell you "We've never experienced this issue before, tell us what happens when you figure it out, and how you fixed it."

Which can lead to days, or weeks on end of troubleshooting wires only to find out you do in fact have bad coil driver, injector driver, or a supplied connector was pinned incorrectly from the manufacturer, or... or... or... or.

Additionally I appreciate the quality of the wiring harness you guys produce. OEM connectors, properly sized heat shrink, I can't tell if it's expanded, braided, or the high temp fiberglass loom, either way it's very nicely done.

I have received many harnesses from companies that cheap out on the split loom junk and a bit of electrical tape to keep it in place. I am not a fan of split loom, it looks like junk and becomes brittle and falls apart in a matter of months, and I end up spending $50 and several hours of my time to depin the connectors, and properly loom a harness that could have been loomed properly from the get go with minimal effort. You and 034EFI are the only ones I am aware of producing wiring harnesses like these for an off the shelf product in the sub $2000 range for plug and play engine management systems.

If you guys need a Power Commander Rep, Installer, or Product tester in the Fairbanks AK area let me know. I wouldn't be able to do it full time, as I love my day job, but I'd be happy to rep a product as high quality as yours with professional backing to accompany it.

You have made tuning too easy... Plug... Ride... View Trims... Integrate into maps as appropriate... Smooth... wash rinse repeat, and you're done in an hour or two.

I can't wait to play with the timing features this weekend.

Thanks for the help Dave! I owe you a beer or two. Let me know if you come up north.
