alright, my vaccuum at idle is at 20 for like a minute and then it starts to idle werid. it keeps jumping randomly from 700 to 1700. i got my injectors fixed today and its not leaking anymore...what do u guys think that is causing my idle to do that??

 

vacuum leak

 

What injectors? What AFR are you tuning it to? How much timing are you running at idle?

 

is it after the middle LED goes out?

I have rx-7 550s i tried to tune it to 14.7...but its at 13 14 15 16 17 moving constantly..hehe..i can't remember what timming im running at...what is it suppose to be at anways...

Brainneck, what is LED? sorry its just so much info at one time i can't remember everything...

 

timing at ten degree....

 

LED Light Emmiting Diode the red flashing things on your ECU

the middle one is warmup enrichment IIRC.

what Braineack is getting at is if the idle goes to pot when the middle LED goes out your VE table/req fuel is wrong and the WUE is masking the problem.

 

The LEDs on an MSPNP are not visible - they're on the inside.

This can be either a further vacuum leak, or just a matter of a bit more tuning. Could you post a copy of a data log of it idling and your MSQ file here?

 

If you ZIP both your datalog and the MSQ into one folder you can upload them in a post on the forum.

 

I will try to get a datalog tomorrow...i don't think its a vacume leak, it didn't do that until i did some tuning...hehe..but maybe it could be...i'll check and check and check and check again...

 

i recorded a datalog but don't know how to post it on the forum...i don't understand what ZIP means...

 

You could just email it along with your current .msq file to our support guys at websales@diyautotune.com, that's probably the best route....
