I would need a log to determine the idle issue unfortunately to see if the IAC is open causing the high idle or if it's something else causing it. Idle for yours is not set that high and you also have the switch enabled for a manual trans so that should eliminate the idle up issue that others had when just putting a 5-speed on an existing auto ECU and not changing anything.

I think Geoff's ecu is tuned the same way but I'd have to check that again.

You can compare; I've had some hanging issues when shifting when it's cold. It doesn't usually do it once it's warmed up, that I can remember, but either way we can look at it in a few weeks if you want.

You can also log onto 60degreev6.com and go to this page. (you can access it without an account too)

And scroll down you'll see the DHP 1.2.4 software and the DB update as well. Download this stuff to your laptop you plan on using for tuning and maybe I can talk you through setting it up.

I just picked up a new laptop for tuning.. I will get that downloaded soon.

I have been "daily driving" it for the most part...

Yesterday sitting idle at a red light it started "chugging" and it wouldn't start... It did the same type of thing like with the old ecm seems like a MAF reading wrong or something... Anyways.. I kept trying to start it and give it gas and after 4 or 5 tries it finally revved up a bit and ran fine after that. Didn't have any other problems.

Then today.. after a cold start I started easily leaving .. got down the alley fine.. then when I got part way down the road it started its chugging type thing again. It took basically the same procedure to get it running again as when it did it yesterday.

Took it on a nice cruise on some country roads today.. found this spot to take some pics, turned out decent I think





It drove beautiful with no issues. Plenty of power even at highway speeds.. get to thinking about something then suddenly you are going 70-80 mph before you know it.

Gearing around 60-70 mph is kind of disappointing.. as the RPMs are at 3k roughly at 70 mph. In town though.. at 40 mph 5th gear seems ideal and keeps the rpms low for good gas mileage. 6th gear at 40 mph is possible but seems to drag the motor too low. The dual mass flywheel with the 6 speed makes all shifts smooth as silk drives like a brand new car. Its a great cruising car now with plenty of power. You barely touch the gas to get around.. the 68mm TB makes throttle input super precise.

I dont think the 6 speed swap is worth it as far as performance gain. For me though, it was super worth it. The 5 speed shift assembly annoyed the hell out of me with how much play there was, I know it seems but the G6 shifter assembly in this car is simply amazing with how direct it is.

Anyways.. 170 miles on the 6 speed as of now. I checked the weather.. no rain in sight until Monday.. I will driving this car everywhere until then. Its definitely ready for Bfest 2014!!!!!!!

Car looks awesome! Nice work man! Too bad the gearing of the 6spd is that high... i was very interested in the swap cause i would like to have some lower gearing for highway but atleast you got rid of the sloppy shifting of our stock trannies

It might be worth the swap just to have a new(er) gearbox.

Kinda like the cropped photo......is a tad dark.

So did you find anything out about the chugging?

Is your tach still set for a 4cyl? Cause according to the calcs I had done it should be about 2100rpm @ 70mph.

No I havent. I figure the tune just needs tweaked. Out of all the time I have drove it, it only did it twice. Its not a steady thing yet to tell what it really is.

Maybe Jon would have some insight on that.. but theres nothing left from a 4 cylinder. All the harnesses are 96 OBD2 V6, ecu is 97 V6 and the cluster is a 96 V6 OBD2 cluster.

What year trans did you calculate? The 06 or 07? They both have different gearing... What I am afraid of is that the junkyard sold me a 06 trans they had labeled as a 07 trans. I thought the tag was funny since the VIN was wrong ...

That's about what my Saab runs in 6th gear with the F40 (and larger diameter tires). It also depends on what gear set you have. I believe I have the 0.62 6th gear.

It's easy to get an estimate on the ratio by counting turns... Rather than guessing so much.

Thats pretty interesting about the gearing... also i didnt knew Opel build this tranny in germany, lol.
Oh and these trannies are pretty cheap here... i have no idea how much they cost in the US but here they go for about $300-$400 on ebay.

michi, yes it's really viable option here, But I have a feeling the mounting locations can be totally different, haven't looked into that tho.
