Nice write up!

How did you post that? You are suppose to be dead today with widespread power outages and tropical carnage!

Just installed my 350tb yesterday and loaded the tune from Lund. I am on E85. Mine almost stalled and ran crappy when first started. After it warmed up and started to adapt to the fuel it seemed to run better but I did not drive it because it was raining. It is sunny today so I wanted to fire her up and see if the start would be better since it had a chance to adapt to the fuel yesterday. So far I'm a bit nervous. It started ok but did not rev cleanly with out pops and misfires. No codes but it ran kinda crappy until it warmed up again. I popped the hood and double checked all the connections and such. I took it for a short drive and it seemed to run fine on the drive. Another thing to note was that I did not notice the loud cold idle when started. It was quiet like how it used to sound after the first 30 seconds as it came off high idle. Not sure if its an indication of something wrong in the tune or something Lund added as an extra feature. Not sure if there is some learning that needs to take place or not but it has never done this before with any of my other tunes. The description of the tune does indicate PMAS, 350im, 350tb, and flex tune. If it continues to have poor cold performance, I guess I will have to email Lund about it.

Initial learn of the ethanol mixture always sounds lumpy , if you continue with problematic cold start you may need more cranking fuel added along with cold idle adjustment

Cranking spark added as well

So far with my 350 IM/TB it starts fine and idles fine. I am just getting some surging while accelerating and a little at coasting speeds. But nothing terrible. That was with the first base tune. My tuner is revising it for me so I'll see how it goes!!

-SUPER IMPORTANT!! This could be a $1000 mistake so please be very careful!! When you remove the 2 stock bolts on the canister EVAP canister purge on the front of the manifold, you will have to carry it over to the GT350 IM. Be very very cautious when using those bolts in the manifold. Ford put inserts in the housing . The bolts go into the inserts. However, as you try to finger start the thread, you will notice that the bolts do not go in like other bolts do. They slightly maneuver around in the hole. If you tighten them and they do not go in correctly, then you will spin the insert and you'll be down to one bolt. This is a costly mistake because if you spin that second one, then you're SOL my friend. I learned this the hard way as I spun one of them. Luckily for me the second one went right in and is strong enough to securely hold the sensor down by itself. So just make sure you are overly careful with this. I recommend that if any of you ever have this manifold put on, then do the next guy a favor and leave that sensor in there and just get a new one. Because like I said, if you mess it up, then you're out by $1000. FYI, I wish someone had stressed the importance of this beforehand...!!!! LOL!!

PLEASE READ!!!!

You MUST NOT reuse the EVAP bolts from the stock manifold, thats why you almost messed it up. You need to get new bolts for here. I think its 8mm thread.

BUT DON'T USE THE SCREWS FROM THE STOCK MANIFOLD!!:eyebulge::eyebulge:

Thanks man. I just wish I knew before hand. I will revise my original post and include your warning. I have bolts that JDM gave me in their kit. I'll try to find out the type of thread they are so I can add that info as well for future installerd. I figure this install is still relatively new to the S550. I mean several people have done it and lots of people know about it. But I don't feel that there is adequate warning about this particular part of the swap. Especially since I was told that several others have made the same mistake I did. But for me, I am leaving mine just the way it is. And that EVAP can stay there permanently. I'll just get a new one and leave this one in there if I ever remove and sell this manifold. Im too paranoid to risk screwing the entire manifold up takingbthat bolt out. Thanks again man.

I'm curious though as mine came all assembled and I didn't have to transfer anything over from my stock IM.

I have had some more experience with it today. It runs great once warmed for a minute or so. It is also around 50-60* today. I think it was more due to the cold and could use some fine tuning of the start up fueling. Driving the throttle response seemed spot on and no surging or other issues at all. It just took a few extra cranks to start when stone cold (which I have seen before) then it stalled on me during the first 10 seconds of idle (I have not had before). On second start up I gave a little gas and it idled ok once it settled. I let it run for maybe a minute before I took off with no further issues. We will see what happens when I switch back over to 93 in a couple weeks. I want to dyno on E85 first before I switch over for the winter. I will send an email about it to Lund and see if they can send me a revision or if they want a specific datalog first.

You only need one diverter valve . The vacuum pod is for the power brakes

Hey guys

Can you just check over my line routing please as I notice mine looks different to your guys but I also used 350 CAI which has one less line to route or cap off:

Does that all look correct please?

Car seems to drive fine but just want to double check!

I have the same set up with the 350 CAI and my routing is the same as yours.

Nice, it is very neat with 350 CAI.

I have the FRPP GT 350 LHD oil separator on its way to get rid of that nasty piece of hose I am temporarily using haha.

 

[Dragster]

Is it possible to connect the Ford Racing GT oil separator to the GT350 manifold?

I have on both sides.
