was it dying?

Oh ya. I got stuck on the side of the road quite a few times

wow, sounds identical to what I am dealing with. Hope it is something I can get sorted out quickly when I get some time.

Ya the worst part is that when it stalls it floods the engine so it won't restart for atleast 20_30 min. Blows big time needless to say I dont drive it to work any more just incase.
I have tried everything I can think of to get it cleared out in a timely fashion but nothing works. And I think it's partially due to my plugs being gaped so tight

[mecpgh]

Oh and I run copper plugs not a normal plug for these cars

Yeah my car does not want to restart until I give it a few minutes. Almost thought I swapped a carb on it and have to let it clear out haha.

Yes not cool at all I've been stuck at red lights and cops roll up and everything

Damn that would suck, mine hasn't been that hard to restart.

Ya like I said I'm pretty sure alot of it is the plugs

Running and not dying!

Increased the latency quite a lot from what they recommend and still need to increase it some more but it idles/cruises/returns to idle without dying.

Runs pretty rough when returning to idle but recovers.

Good to hear

Do the Deatschwerks 1100cc side feeds have as many problems at Five-0's 1200cc side feeds? The Deatschwerks cost twice as much.

it's big side feeds in general that arent reccomended

The fueling is all over the place at idle. The fuel corrections will be flat one minute then out of nowhere the afr will shoot rich and corrections swing wide. That may last a few seconds then back to normal for a while. But corrections still arnt what I would call acceptable.

As for idle control. SUCK! You can stop at a light and idle corrections are ok, stop at the next light and corrections will be -25. Next light they may be ok again. System voltage is stable, maf voltage is stable, map, all the data is correct and nothing to cause this behavior.

I would not recommend these injectors to any customer or client to install on there car.

That's pretty much where I am at with these same injectors. Once second they're at -25, then +25, and shortly after back to -25. I've played with these for a few days now and I think I'm done trying to work with them. I've gone high enough in latency that the ECU couldn't command a smaller PW, back it off and then it's back to being all over the place.

Moral of the story: side feed fiveo's are poop. My 1600 top feeds are still fine but eventually I'll get some id2000's.

The injectors are garbage. I've tuned many dw large side feeds without issue. The owner of the car I refered to with these injectors ended up buying a top feed conversion kit with id1000cc injectors and he can't be happier. Here is a link to his turbo upgrade with injectors.

dw's biggest sidefeed is 1100....unless people are getting custom ones made.

so its 10% less flow which is helping out.

i just dont think running a sidefeed >850cc is a good idea. bigger than that should be converted to topfeed.

If you read the bottom it explains a lot.

Thanks for that post. That explains everything about why the five-o side feeds don't work properly. Sorry for all the guys that got sucker'd into buyings these from five-o motorsports. They know they suck yet still keep selling these.

Those are actually the PE Injectors, not quite the same thing, is it?

They're based on the same core, I would think. I don't think PE makes the injectors, for example. They take a core and mod them. Since PE is doing the modification, they're branded as PE injectors. But only several companies actually make injectors.

I have to say that my AEM is doing a pretty good job of holding 14.7:1 on pump without misfires, and I have the 1200s side feeds. The latencies were WAY off though. I'm running something like 1.2 ms at 14v. If the site is correct though, I should measure the resistance between injectors and then it looks like the flow may change over time. I couldn't get them running on the stock ECU however. I had every problem listed in this thread.

Ya stock ecu closed loop is too sensitive, my car is super smooth in open loop @ idle, same concept with aem

i second this. my car has run much better after converting, still a pain to do the conversion though. dont get the black 1200 topfeeds, that look like injector dynamics ones, they are too short, they still seal on the rail but i suspect them not sealing at the tgv as there is no clamping force down on them, they leave 1/8-1/4" room to slide up and down in the rails, i posted pics in a thread i think somewhere here.


also, agreed, ron is a tuning wizard, we ran out of fuel and decided to hold off, and now i'm looking at a different turbo with better spool anyway lol. life...
