Hey I got some base maps from the Datalogit forums and other places online, but I'm not quite sure how to tune them to my particular needs. There were a few things that were confusing me so I figured for now I'd leave it alone. I just need a base map to get my car broken in before I can get a professional tune on it. If someone could hook me up with something that will make it run safely that'd be super sweet, I'd really appreciate that. I'm looking for a low boost, rich safe tune until I get my engine broken in. Here's a list of my mods:

Garrett GT35R single turbo
Full turbo back exhaust, no cats
850 primary, and 1680 secondary injectors
Aeromotive 340 Stealth fuel pump, tuned to 42psi?
Koyo rad
Greddy FMIC
No OMP
Ultra MDI ignition
R6725-10 spark plugs
GM 3bar MAP sensor
Large street port

If you need anymore information, let me know. Again, any help would be greatly appreciated!

 

Here we go again with newbs not understanding the difference between breaking in an engine vs. full boost driving, and maps.
Almost any map is good enough for breaking as long as the injectors are set up correctly.

Re-init your map and then setup the injectors to match yours and it will be fine for normal non boosting driving. But it will take a DATALOGIT to setup those 1680 secondaries.

 

Here we go again with guys assuming people are newbs. I don't really think a 21 year old "newb" would rebuild his own engine and transmission but sorry for asking... I have searched and done a lot of research and know that any map should be fine. Didn't think it was too much to ask for a little help though. I do have DATALOGIT, I do have some base maps, and I do know how to set it up. But seeing as how this would be my first time actually playing with it, I didn't want to test it on a new motor. But thanks anyway!

Thats pretty funny...

OP, you'll need to setup your MAP voltage too.

 

Haha yeah I'm not stupid.. I've read my PFC manual, FC Datalogit manual, and every write I could find online. I already made my own map with the GM 3BAR values and set up my injectors I just though it wouldn't hurt to ask someone if they could possibly share a single turbo tune similar to mine for a better starting point. This is my first time playing with it, no ones born a professional.

 

As others have said you should be fine to break it in as long as your map sensor and injectors are set up properly. Since you are just starting out on a tune I would recommend getting rid of those 850 primaries, they suck and you can save your self some re tuning time down the road by going with 550's or ev14 725's.

 

Well I did set up my own tune now, and it starts and runs great until my water temp gets to about 65 degrees celcius. It seems to be way over fueling, the car won't idle anymore and needs a lot of throttle to keep it going. What sucks about the 850's? Are they harder to tune? I have my map sensor working well, and as far as I know my injectors are set up correctly also. I just can't figure out whats causing it to over fuel.

 

The 850's will idle way too rich unless you add a good bit of negative lag which affects the entire map not just idle. It's an old work around not really needed anymore with the current injector options available.

 

I had to add negative lag even with ID725s. It wasn't for the idle but for higher vacuum areas would go to 11 afr because of the minimum pulsewidth that the power fc uses. Anything less than like 2.4 does really do anything for me. You can set it at 2.3 or 1.3ms and it doesn't make a difference. Right now I am at -.17 lag and it's working great. I've heard with 850s old style injectors you have to use like -.40 or such.
