idel is ruogh, plugs are black
 

THe plugs tell me im running very rich, and the idel is very rough, maybe I foued the plugs? Im using DIY autotunes PMP after start enrich charts, and I have 305cc injectors. What should I do to get it idleing smooth?

Did you set the req fuel for your injectors? Why don't you have a wideband O2?

well first of all did you reconfigure your REQ fuel?

edit: beaten like a red headed step child. Gotta refresh more.

req fuel is set, 1600cc car, 305cc injector, 14.7 to one. I have a wideand and it says around 15 to one.. nd it wont idel well at all.

You need to add fuel in your fuel map in the idle cells. Tune it so your wideband reads closer to 14:1.

Change your plugs.

If you are using the PNP map you should have used 13.1 for your AFR in REQ Fuel. Thats what DIYAutotune uses for their map.

+1

ok, I loaded in the whole DIY autotunes Megatunes settings, and set the req fuel like you said. It still runs like shit, barley idles, if at all. the plugs got black again quick, and smell of gas. The oil looks fine, everything looks fine. im at a loss of what to do..

remove fuel from the ve table. :confused:

well I drained the oil.. and when it was all in a bucket it def smelled of gas. I must be running so rich that it is fuel washing the cylinders.. shit. hell at this point I might only be ruinning on a cylinder... i dunno. Im totally lost.. and panicing.

oh thank you god! I plugged the stock computer and AFM in and it runs like a charm.. oh man I was scared I blew the engine.. OK so its definitly something in MS.. what should I check?

looks like you need to give it less fuel. try running tuning your req fuel until it idles smoothly and then retune your ve map. try starting with 11.5-12 in req fuel and go from there. change values by .3 in either direction and see what it likes better

req fuel is 13.1 on the 9093 diy mspnp.

You should be using a PCpro if you can't handle removing fuel from your fuel table. Then again, you would still be dealing with cylinder wash with the PC if Tom tuned it anyway.

Did you figure out how to remove fuel from your VE table yet?

yes I do...
For some reason it seems like takeing fuel from the points around idle dont make a diffrence.. maybe I have to take out more? I took about 7 to 10 away from DIY autotunes map...

Your signature says you have 460cc injectors and your post said 305cc, which is it?

I find that 1 point of VE will change my A/Fs around .3 AFR on stock injectors, that amount of change will increase with the size of the injectors.

I just got the 460cc injectors, imma put them on tommorow.

Would anyone be willing to share their settings for 460cc injectors? Atleast that should get me in the ballpark.

If changing your fuel has not done much, I'd also check your timing with the MS installed since it's a new install to make sure that when MS thinks it's 10 BTDC, the engine markings say the same.

i guess i could send you my last msq. 460cc 13psi and t3. should get you close.

its on my laptop....will post laterz.

and are you burning the changes to the MS?
