how to time a 97 w/ a 6 bolt engine

[Ilikespeed]

I have a 97 talon awd that i stuck a 6 bolt in w/ a 1g cas. How do i time it?. Its not like a 1g w/ the plug to ground next to the battery... unless i dont see it?...

Brown connector located near firewall or battery.

Did you even attempt a search? There are numerous topics on it.

2g's don't have the timing connector, with the exception of some 95's.

I think the connector is a different color on the 2g models and I believe arctic is correct in that only some of the 95's have the ground terminal. If its there then its right next to the cruise control servo. There should be 2 or 3 of them. Black, blue, brown if my memory serves me correctly.

Brian knows because he corrected me last time I posted on this topic.

Ground pin 52 at the ECU...

Just use a logger and an adjustable timing light.

Yea but you need to lock the ignition timing at 5 btc or else the timing is going to be jumping around to much to use the timing light accuretly. 95's have a tan connector on the firewall to lock the timing at 5 but 96-99 don't. That tan plug goes to pin 52 on the Ecu...
so ground out pin 52 and the ignition timing will lock at 5 just like a 1g then use the timing light and adjust the cas accordingly.

DSMLink has a feature that allows you to ground the timing. You can also get rid of misfire problem that can occur with the 1G CAS, using DSMLink.

Rich do the 97 ecus lock 5 degs with pin 52 grounded?

The 95-96 ecus have the Ground for Base Timing feature.
The 98-99 ecus do not have it, you need to use a ScanTool.


OP, the 97 ecus are a transitional ecu, it was the first year a Hitachi cpu was used.
The 90-96 ecus use a Motorola cpu. 97+ are Hitachi.

With the 98-99 ecus, you can use some OBD2 Scan Tools to send a command to set Base Timing, you can also use EvoScan software to do this also.

The 97s you will need to either Ground Pin 52 or use a Scan Tool to set Base Timing. I am unsure which feature the 97s support, it may do both.

You can also just log Timing Advance and try to match it with your Light, but this is the most inaccurate method.

Did this work for you?

I have a 6 bolt/1G CAS in my '99. I've only tried the "match timing to logged value" method but it seems that I could be off by +/- 3 degrees. That would be fantastic if grounding pin 52 works.

Ceddy, do you happen to know if the scan tool that you can borrow at Autozone, etc typically has this feature?

Yes it worked for me... Although I do have a 95 ECU my wire harness didnt even have a wire coming out of the plug, so I stuck a wire in the empty hole for the connector and plugged it in an it grounded out that way...

 

[jrohner]

It should be pretty accurate if you hold the RPMs up high enough to where the timing is stable.

 

[donniekak]

With a logger and timing light, you move the cas until the light, and the logger match.

Sorry for the extremly late reply.
Yes Artic, I have searched the forums and for sum reason Im unable to look at or enter a topic search for this application. Didnt think to look under bolt on tech, and the newb section didnt answer any of my quetions. Im am not new to dsm's, frankly im sick of all vehicles.
This car is a 97', and that explains the missing brown plug, I dont have a datalogger so cant do that. Its taking me time to get on and post and I apologize, I have a shop to run... U understand.
Pin 52 is the next route and thank you for all the info.
