2G 1g cas timing in a 2g

[Steven A Schiltz]

Kinda having an issue with my ignition timing when I try to set it on the logger it shows 13 degrees when the engine is close to five and vise versa when I move it. It has a 92 green top cas and the previous owner did his own wire tuck and from what I seen there is no crank plug at all it's all run off the 4 pin plug. I'm running a 98 black box ecu. And have a tactrix plug and ecu flash. Everything looks like it's in the 2g factory spots as in the wires. My question is do I need to swap some pins around on the cas, ecu, or do I need to tune it?

Base timing and ignition timing are not the same thing. Is this what you mean?

What I was meaning was I can't get my mechanical timing to match what's on the computer. Sorry was trying to thing of a way to word my problem . If I sent it to 5 degrees at the crank on my logger it shows it's at 13 degrees and when I get the logger to show 5 degrees the crank shows 13-15 degrees

You need to lock timing at 5 deg. I am not sure how or if you can with a black box ecu. 97+ cars either need ecm link or some form of ecu to lock it or I have heard a good scan tool can. Then you can set cas at 5 deg.

Scroll down the page to where it says "Base Timing Terminal".

You add a pin and a wire to ECU pin 52 that you run to the engine bay. Then you enable the checkbox in ecuflash and reflash the rom with that checkbox enabled. Then you simply ground the wire you added to force the ECU to lock ignition timing so you can set it by adjusting the CAS.

So add the pin, enable it in the mod bits, and ground out the wire, that correct? Now when grounding this out to the battery or any point on the chassis ? Just double checking to make sure I'm getting right. I must have missed that delta448 but thanks guys

I wouldn't use the battery post, but maybe slip it under a hold down nut or something fairly secure. I'd probably use a crimp on spade, and just slip a female spade over it to shield it when not in use. Then all you need to do is just hook the timing light signal pickup to #1 plug wire and adjust the CAS until the timing light flash shows you the 5btdc mark.

That's what I was thinking about doing. Read my mine so I don't have a random wire floating around. And thanks again tryed to search around for this info but it did seem to be there or maybe wasn't sea ching enough
