Allen Nelson - last resort to contact you.

I know your busy man, but i left a message Tuesday and called today and no answer.

It's about the tune I got for my bro in laws ls2 swap. It ran lean burned 2 plugs and scared the cylinder walls bad. Motor is at the machine shop getting more money spend on it. I wanna make sure the tune doesn't have to be adjusted when I drop the motor back in so this doesn't happen again. The first tune I was told the wrong cam specs 222/234 or something lake that and you said there wasn't much to change for the actual cam 222/224.


Please call me man. I don't wanna have to pull this motor again and them have to spend more money on something we can prevent with one phone call

Dang...you still running that Fuddle, Daniel?

That sucks to hear. Depending how bad the cylinder walls are it might need a few sleeves... what's the compression on that thing?

Yeah. But this isnt on my truck. Its on my bro in laws. I put a Circle D in it

To tell you the truck I am not sure. Its got stock pistons and 243 heads. I really hate to make this post, but I dont want to have to go through all this again. I would think the tune would need to be change for a different cam, but he said it wouldnt.

IMO, i'd get a wideband ASAP. Allen seems to run his tunes a bit on the rich side to be safe, so that slight adjustment in cam was probably within wiggle room. Every motor is different, it's hard to tell what happened. A wideband should have redflagged you before anything serious happened.

Allen is usually super busy, try emailing/messaging Ericka, she's usually a little quicker to reply. I've never had any problems with his services, I just learned to wait a week or so between contacts. All the local tuners around here are the same way. My buddy had his camaro at ls1speed for almost 2 months to get a cam/head/tune. We all know that is a 1-2 day project.

Daniel, right? I think so, 254 area code? That's the only call I see on Tuesday, Erica left a message, did you not get it? I'm only behind on calls from the 5th, unless a few got skipped.
You can always PM me with "important" in the message if i'm not available when you call.

Odd it only burned up 2 cylinders, but you never know.
What was the wideband reading ? Not that is helps when one or two cylinders blow, because a wideband is a collective reading, meaning it's averaging all the cylinders. That's one reason why we run them on the rich side.
Meaning 12.4-6 on NA setups and 11.2 or so on FI setups.
A change from a 224 to a 234 only on the exhaust side wouldn't make it run lean to the point of causing damage.
We do run our tunes on the rich side and it's tough to blow an NA engine with light mods.
Practically every tune we send out is always tuned on the rich side, the ones that aren't either have lower fuel pressure than a typical vehicle, dirty or not enough injector, etc.

If you don't want it to happen again, get a wideband and see what the a/f ratio is.

I can send out a tune that is definitely going to be richer, but be sure fuel pressure, idc and all that other stuff is up to speed.

we'll get a hold of you today,

allen

Thanks man. You can delete this post if wanted. And no Erica never called, I dont have a voice mail or anything. And it was cylinder 1 & 3 that burned plugs. Please call me today.

Not sure if you remember me but Im the one from the lightning shootout yall met up with in Waco. I had to borrow your extra pair of jeans to beable to run that night.

Yeah. It needs a wideband, but its not my truck and not my decision, i told them to get one but ya know how that goes. The motor will go in next week thats why I am in such a rush to atleast talk to Allen and figure out what the issues could be.
