Looking for a new ECU for my car that's already socketed, no DSMLink needed, PM me if you have one for sale.

Thanks.

I've got an eprom from my 95 tsi 5spd for $200 if you want it.

I won't accept a lower price.

They go for $240 usd on ecmlink's page and they're available for $110-$150 usd from tuners, plus shipping.

Thanks Mike, I'll get back to you on that one, $200 is a bit more than I was hoping to pay, its really just for diagnostic purposes to make sure my ECU is okay.

Did you inspect it for blown resistors or leaking capacitors?

Yep, they were replaced two years ago by ECMLink and the board looks perfect, just need to cross it off the list for sure.

I have multiple threads on the subject but the jist is that the ECU is dumping fuel while cranking the car causing it to flood and I've tested or am currently testing every possible reason. Every sensor is sending an appropriate signal to the ECU but it still commands a pulsewidth that's about 8-10X what it should be, some mornings it takes 45 minutes to start the car and this is my DD so I'm getting desperate, been working on the problem since the day I bought it three years ago. Other than starting and a rough idle it runs well.

Wish I could be more help.

Doesn't sound like a fun problem to have.

Trade me your 272's and I'll give you a sick deal on 280's.

Nope, It's honestly adding a significant amount of stress to my life haha. I'm actually switching to stock cams soon, I think the 280's would only make the problem worse.

What are you basing this on? When I compare your attempted start log to mine, the injector PW during cranking is similar (mine is about 10ms with a global fuel of -50%). The only difference is that mine fires right away, and yours doesn't, so the longer you crank the more likely it floods.

If your compression is good and you have a healthy ignition system, then maybe its your cam timing. I don't think your ecu is dumping too much fuel.

I've looked at a few other logs and have seen an IDC of 0.4% or less on all of them where as I'm seeing anywhere from 2-4% IDC while cranking. Nick, what is your IDC while cranking? and what injectors are you running?

I mostly look at actual PW (inj on). injectors are FIC1050SP. Stock cams. here's a log from a couple of weeks ago when the mornings were not so cold. PW would probably be even higher now that it's cooler outside.

coldstart log

I'm at work so I can't check it out right now but I'll look tonight. I'll have stock cams to install after this weekend and once those are in I think the diagnosis will be easier. One of the likely culprits is bad cam timing causing a loss of compression at cranking speed and if you're saying that my fuel is fine then the cams are looking like a very likely answer.
