I have a smilar setup as described above: ESS G2 on 7psi, mu52, lethal bap and I'm a happy camper with 633whpP1X - I actually went with that one to combat the boost a little better.
But ya, thatās a lot of time and money for only 3psi. After talking with them, they also would not be able to update my tune for the lower pulley size which I can understand.
My expectation was to I would need a custom tune this whole time anyways but their last revision with the current set up seems to be pretty adequate so it would have been nice if that could play nice with the lower pulley.
On the note of going with a custom tune. Ive had a local shop recommend (but not require) going with some LU47 Injectors and a BAP or DW400. Also chatting with Wengerd a bit as I have heard some good things from them and he has said as long as I'm staying under 7psi he can tune the current system as is.
So the question now if others want to chime in, is if the stock fueling can handle 6ish psi, is there any reason to jump to the larger injectors and pump? If the only real reason to do is to have room to grow in the future, I'd rather cross that bridge when/if I get there. I'm definitely not opposed to adding the injectors and pump, but I also don't want to buy things I do not need.
I know it has stock injectors but they still have to input injector data. if they put the wrong injector data into the tune then it will cause that same problemGood to know. Thanks everyone. Ya until I get this all dialed in I am watching my SCT like a hawk. I actually have it set up to just datalog straight to the device so when Im driving around I dont have to have my laptop everywhere I go, makes things really nice, plus the display readout of a few of the key parameters I want to see in case things go south is nice.
@Jackson1320 bad data somewhere makes sense. The HO kit on the 2019 GT did not come with any injectors, so the injectors currently in the car are the oem ones. A vac/boost leak was my first thought on this as well so I did a smoke test on the whole system but didn't see a single leak anywhere, so good to rule that out.
Procharger's tuning said they would take a look at a log but that it is very unusual that a change would be needed. I would say fuel trims that far off are unusual so regardless of what the issue is, tune or hardware, hopefully they help me get it sorted out.
You definitely have a problem because you should continue to build boost all the way to redlineYep did a few pulls to confirm and am only seeing 3-4 psi and that is all the way at redline. I did notice, and the logs seemed to confirm this, that it is hitting 3 psi at about 6k rpm and then holds there to redline.
Well, got a revised tune from Procharger and gave it a quick try.
Fuel trims seemed to be quite a bit better but still not what I would call ideal. Bank 1 seems to be within 5-10% but Bank 2 is still in the 10-12ish% range. Still looking pretty rich though, a few place in the logs are showing an AFR of ~10.5 at WOT.
Still not seeing any knock showing up, car is showing it is still advancing timing across the board but I'm only seeing a max of 3-4 PSI at the moment so things are very mild right now, a little too much so.
I decided to also log the Total Misfires Since Key On field and was a little surprised that a 30 minute drive would yield 32 misfires. I don't know if that is considered normal. Have any of you logged that field? Not seeing any check engine lights and I cant hear it misfire, but the car seems to have logged several occurrences of it.
Cant go wrong with DaryleAs a quick update to this, I ended up dropping down in one pulley size (4.38-->4.25) and that put me at 6 psi at 7300 rpm.
I also went with Wengerd on the tuning and can say that his tune seems to be 100% better than the previous Procharger tune. Not wanting to speak poorly of Procharger as they team was great to work with and sent me several revisions, but that being said, I was a little worried to drive the car based on what I was seeing from fueling alone when I had their tune. It was rich in some places, lean in others (including a few places under boost) so I was generally not feeling to great about that. Not to mention the fuel trims were all fairly high even after the few revisions.
I can say that the first draft from Wengerd had the fueling pretty much spot on and substantially better than what I was seeing from the Procharger tune. I still need to put some seat time in the car, but my initial impressions are that I am no longer worried about the car hitting 13.5:1 AFRs at 6500rpm under boost (which it definitely did with the PC tune)
Ill plan to add a few updates and final thoughts on this whole process since I learned a few things along the way as well as some info that I just couldn't seem to find that would have changed a few of my initial plans on this set up. But overall, I'm excited to do some driving in the car and see how it feels now that it has a good tune on it.
Those will work however I've found the ngk 95822 gapped to around .026 to work much better they are a plug designed for boost, they last longer as well. The 6510 was just an easy to get plug 10 years ago so everyone has been recommending them since. Nobody ever really researched or questioned to look for something better suited so everyone just keeps using them. That plug was not designed to be used at those tighter gaps for boost. There are better options now like I mentioned though.Thanks. Plugs are NGK 6510s gapped at approx. .30. The documentation I got recommended a range of .28-.32 if my memory serves correctly.
Great to know. Ya I just went with what seemed to have been recommended a lot. But I may look into those if they are a better fit for the application. Right now, the car is running very strong with the tune from Wengerd. Very noticeable difference so far.Those will work however I've found the ngk 95822 gapped to around .026 to work much better they are a plug designed for boost, they last longer as well.
