Holley stuff

[wfox2506]

Taking a crash course on how to tune with Holley V3. Got it running and driving pretty well. Working out kinks in the idle and AC use. Does anyone have a global file I could reference? Non turbo car.

Unfortunately, you probably won't have much luck. Pretty much everybody on here is running Megasquirt.

I'm no expert regarding a Holley. Most of the DMC carb guys are running Autolite 2100 carbs. About 3 or so of us are running a dual Solex system found on the Peugeot 604 and Renault Alpine A310. There is also at least 1 dual Webber 3bbl setup that I know of on a Delorean in Ohio.

What manifold are you running?

[wfox2506]

Stock manifold, DPI stuff.

2 days ago the car wouldn't start but now its running pretty well, so I'm making progress on my own. Reading up on Holley forums and such. Only gets me so far since I'm working on a Delorean though.

My main issue right now is that I can't even tell if the IAC is working or if there is one.

[opethmike]

Take some pictures of your setup; we can tell you if there is an IAC.

[wfox2506]

There is one, I found the IAC readout and it's working.

I'm going to try some tuning this weekend after a couple weeks away. So this is where I stand:

Cranks fairly quickly but lazily with a very low starting RPM. It helps to give it gas to keep it going.
Idle is too low and IAC reads 100% most of the time.
All adjustments in the idle tab seem to do nothing.

Otherwise it runs fine. Nothing I do seems to get the idle RPM up. I temporarily have the idle screw turned up as a remedy.

This is the EFI from DPI? Contact Josh and see if he'll offer support. He should.

[wfox2506]

Ok, undriveable '81 car should pop up on ebay/craigslist soon. $20K.

dont give up!

[opethmike]

dont give up!

100% agreed. Especially if this is the DPI EFI kit, Bengston needs to help you out. Have you contacted him?

I can remote log in tomorrow am. Still need to update throttle body to our current offering on my next trip down.

[wfox2506]

I got the car running great this weekend by just spending time on it. My problem now is that the IAC seems to do nothing. The IAC position value fluctuates, given whatever I'm doing, but it doesn't seem to actually change the AFR/idle.

What I realized and am going to try today:

In desperation to get the car functioning again I turned the idle screw to get more air. Everything that followed resulted in a smooth idle and some good test drives but AC kills the engine at idle and IAC isn't working. Today I plan to close the throttle plates as much as I can without binding. Then try to tune from there and hopefully the IAC will work.

Aside from that, I could really use some tables to reference but haven't found a whole lot on here.

[opethmike]

Very sad to see that the vendor who sold you this has provided zero help.

I'm not sure what IAC valve your setup uses, but have you checked the valve itself for physical functioning? That is, some sort of bench test?

[Delorean Industries]

Already offered. Owners are welcome to try things for themselves. And your definition of zero help means not answering questions on here. It's not my job to educate trolls Michael.
