BNR LS7 Coil Upgrade

[2014 Blue RS]

Instructions don't say if I can proceed with installing the coils or if I have to wait to hear back from Jerry

Shouldn't be. Base tune just means it's a more generic tune to get you started. Jerry will refine it and dial you in for your car.

I just installed my LS7 coils on Wednesday, loses my tune and I've been good to go. Gonna log and have Jerry dial it in, but everything has been running great.

Sorry, responded to your last post and then just saw this... don't install the coils unless you have a tune file from Jerry to do it.

How it worked for me when I got the GTX... I got the tuner, used the tuner to read my car's ECM and TCM (for auto) to make a copy of the files on the handheld, then sent those files to Jerry and he made a tune (the initial tune I referred to as a base tune).

I'm pretty confident it should work the same way in this case... Once you have that tune file, THEN you can install the coils and load the tune onto your car via your handheld tuner.

Was hoping someone could clarify. My coils are arriving today or tomorrow. Already have a bnr tune set up for 93octane. Do the coils require a new tune file before installing them? Or is it just plug and play (then log) if your already tuned? Thanks in advance

You need a new tune with the correct dwell and coil settings.

Thanks, thats what i figured but i had to ask

I was wondering if you could get the Bracket/Cover painted white? It is not currently on the list of colors, but what would it cost to get a custom color?

The base tune is in and it is a noticeable improvement. Pulls more consistent through accelerations and the tranny shifts are way smoother. Also the motor is quieter. Assuming this has to do with less boost pressure?

Previous tune was good driving at speed but if I accelerated too hard it would cut out and shift real funky. I used to think this was due to my tune being set to lean maybe. After seeing the LS7 coil upgrade, I suspected loss of spark like others described. Now I'm sure that's what it must of been. So happy it's running right.

No regrets. NONE.

I was wanting to know what the difference (besides $$) between the Black MSD, Red MSD and Yellow super coil with this upgrade? Would the OEM do just as well as the previous mentioned options?

Color

Just use the Factory coils unless you want a different color. OEM LS coils have made over 1000whp, they'll be just fine in our Sonics.

Thanks again, I just saw previous replies to my question, thanks again for the reply

Do the coils give a performance boost in terms of more hp? I know it's smoothes idle, more mpgs and prevents blowout. All I have right now is a BNR tune. So, would I see any kind of improvement with adding this coil set?

By itself? Not much if any. Pretty much all of the gains you will see come from the tune it requires.

This is predominantly a supporting mod, allowing you to push higher boost without misfires.

I just ordered my LS7 coil upgrade from BNR. It said that there might be a 6 week lead time prior to shipping. Does it usually take this long? I was hoping to have it before the end of the month.

Thanks

Mine were just delivered. Just waiting on my tune revision to be emailed. Turn around time was a quicker than expected for the hardware. Definitely can't wait to install them and give a review.

I know this post is old, but no one ever answered the one fellow who asked:

Can these be done on the 1.8L? Or is it exclusive to the 1.4L?

We're working on it for the 1.8, should be out soon.

Glad to hear it, because I'd love to gap the ever-loving hell out of my plugs.

FYI the tune for the coils works for any option of coils; whether msd or accel, the tune is the same.

Also, what gap are u guys running on them plugs? I hear that after the tune and other upgrades we could benefit from closing the gap by .002 or more depending on how aggressive the mods are.
