Due to your clogged fuel filter? What's your next moved after installing the new fuel filter?

The clean filter picked up 5psi but it still fell on its face.

My plan is afpr, BAP, and new fuel filter and then we'll try it again. That assumes I can figure out what's up with the intake (at least I assume that's the issue). I shouldn't be getting wild AFRs at cruise on the freeway. This intake did that when I drove it before it was scaled...it's better now but not close to good enough.

I have a fitting for the afpr setup ordered from Boomba and bought a BAP from DB today. I'll throw the BAP on this weekend. The other two when I have all the parts together.

Looks like a blind monkey could install this thing. That is perfect for my skill level.

It's 40amp...total overkill but that's what DB stocks.



I cut down my intake shield and I should have left it a 1/2" longer. Crap. I hope it helps anyway.

if you dont mind me asking how much does DB charge for one of those?

$275

And worth every penny!

Good luck and hopefully you get everything figured out!

Last night I got the afpr attached to the car after making a slight mod the bracket that simulatedwood had thrown together a while ago. I'll probably try to plumb it in next weekend.



Got the BAP installed early afternoon. Went out and did a pull and the car died in a fairly impressive way. Spent an hour troubleshooting and a support call to scheides but just had to replace the fuse for the fuel pump. It's a 20 amp fuse and the Bosch 044 at 17volts was probably trying to pull low 20's.



For now I removed the step-up voltage feature. Not sure if I want to risk a larger fuse on that circuit or not. Maybe I need to find a properly sized resistor to turn the BAP down to 14-15 volts. Opinions?

The car continues to run poorly. P300's, o2 sensor slow, bank rich. I pull over to pull CEL codes once or twice on each drive.

Throw a 30-amp fuse in it.

I found a chart showing that the pump draws 17 amps from the BAP but the BAP needs almost 30 to work its magic. Given the gauge of the stock wiring, that's quite a draw...triple stock.

[Kracka]

The stock pump gets closer to 14V with the engine running so you'll probably be doubling the amperage draw.

Thanks Kracka. I ordered a couple assortment packs of fuses off Amazon. I'll revisit that when I get the parts for the afpr install.

The car issues are disturbing my Zen so I think I'll read this month's DSport and chill out today.

I believe there are spare fuses in the fuse box that you can use.

I think it was 5,10, 20amp. I used the 20 when it blew.

[scheides]

Maybe not, I think there's an article on fuel pump setups in it:

LOL!

Drive your silly ass to Walmart and buy a big pack and throw a 30 in

When you can get a 120-pack assortment from Amazon for $8 or a 6-pack at the convenience store for the same price then it seems like a no-brainer to me.

I'm going to stop fucking around with the ID2000 injectors. It doesn't look they are ever going to be 'drivable' in any real sense. It's noticeably better now with the settings that Tephra has found but idling and not misfiring even 99% of the time will still result in endless CELs and embarrassment when the car dies in heavy traffic.

I have a set of DW1300's on the way.

[Kracka]

That sucks man Glad you're making progress though.

[FattyBoomBatty]

Oh snap, I'll give you 100 bucks for those used 2000's.

I'll leave it up to Shane whether we should give up on the 2k's. The 1300's would be easy to resell if I need to. I'd just like them on hand for my next visit to DB.

My problem is that the ID's and the intake seem to have turned one problem with my car into three.

1) AFR fluctuations at cruise that spike up into the 18's and cause the car to slow down, for lack of a better term. I assume this is a problem with the intake design since I experienced a similar (but more severe) version of that before the intake was scaled.

2) The car idles at 14.5-14.7afr on cold start but it idles at 13.2-13.4 the rest of the time (on my gauge). When I go to leave a stoplight the car bogs/stumbles/dies when trying to transition from 1k-2k rpms (where I normally let out the clutch).

If the injectors are too large to transition smoothly from idle then they have to go. If there's another table that can be tweaked for this then cool.

3) The fuel pressure drop above 7k rpms. I have a new fuel filter and BAP installed. An afpr should go in sometime this week. Not sure if this stuff will solve it but it's the last reasonable set of things to do before ripping the Full Blown system out.

That sucks, I have only heard good things about the ID injectors besides them possibly having issues on your car.
