Where is your intake air temperature sensor located? It is sky high in the second log and causing issues... Does this thing have an intercooler?
Also, do you have a fuel pressure gage? Want to make sure it isn't fluctuating - with the fuel I added in the first tune, it should have richened up more than it did...
Is your transmission slipping? In the second log, it looks like you hit it pretty hard a couple times and it doesn't pick up much speed...
Here is another tune richened up further...
My iat is located in the air filter housing about 8 inches from turbo intake, yes I am running an intercooler with this system
Unfortunately I do not have a fuel pressure sender just a gauge mounted to the regulator. I will have to try to run the tune tomorrow as I just got called out of town for work.
I'll send a data log possibly tomorrow.
Thanks again. :)
Any chance you can take a picture of your underhood setup? Something will have to be done about that IAT - it is reading 171F while you are driving! It really needs to be on the throttle body side of the intercooler - that is a more true indication of the air going into the intake...
Did I tell you this was going to be hard over the internet? If I didn't... this is going to be hard over the internet! LOL!
I can forsure upload a pic of
My setup. I will have to do it tomorrow Aswell. I'm replying from my phone. If I was using my noggin I would have brought my laptop and hooked it to phone. Hey now it it was going to be easy I wouldnt have done it because then everyone else would have Had done it already. I think
I remember you stating this will be a difficult monotonous task. *evil* :laugh:
LOL! Okay, I'll check back tomorrow.
Awesome. If you lived closer I'd have to take ya for a beer, wings and a bull$hit. I will owe you for sure after all this help.
Oh hey I just read the transmission slipping comment. The trans is brand new with a 2700 stall so that may be the issue. and if its slippin ill just go till she blow then do a 4l80 trans and t case swap. But she did hook up really nice when i just had the 427 non turbo so its hard to say.
Yeah, it would be a bit of a trip LOL! Glad I can help.Quote:
Thing is, if it is slipping, you can't tune it like that... the loading won't be correct. I'll keep an eye on it in the logs.Quote:
I want to see the pic of the intake, but I'm pretty sure that the IAT sensor will have to be moved before we go much further - that messes with fuel and timing...
Hey. I ordered a new iat temp sensor on the possibility it is bad. The sensor is in the air filter
By the turbo. Haha that would be a long trip. I won't be home until late tonite so pictures will have to wait until tomorrow. Also my sensor comes in tomorrow so that's convenient. I kinda hope the trans isn't slipping... MasterCard isn't wanting to fund my project so much no more. Who knew they wanted to be paid back. :laugh:
Sounds good - I'll check back tomorrow!
