Re: Y8 Timing
So I got my wideband back. And i can't seem to get any sort of a decent fuel map out of JD's map. Is it just me or is it completely way to rich in certain spots? Am i doing something wrong? All ive even done so far is to modify the fuel multiplier. I cant get a 14.7 idle unless i put my injectors all the way up to like 600cc multiplier. Keep in mind these are dsm 450s

Re: Y8 Timing
Hell if I know. What us your fuel pressure? Have you tried changing fuel values to tune your AFRs? Different ECU?
Crome is wierd, it does not always save fuel multiplier when you save a .bin... Start with Crome 1.1.14 or the 1.2.0.24 beta (NOT 1.2 Final) with ABT+ 2.0 and FVFT 1.99 RC4 and do a straight recurve for whatever your injector size is... then start adding values to the offset until the car idles perfect. At that point it should operate in the NA range more or less stock.

Re: Y8 Timing
Stock fuel reg, stock pump
Well it started to do it out of the blue..ie i wasnt tuning at the time. on your bin, i can get the idle pretty decent of o set the injectors to around 600cc. so the fuel multiplier is making some difference. but when i d\try to drive it afr go crazy rich, normally between 9 and 11 afr. note, this is while running a basemap that has always ran fine for me in the past.
I'm, going to send off my injectors if the injectors seem like a possible cause

Re: Y8 Timing
I sent them off to www.injectorservices.com and they did an awesome job. Shipped back the same day they received them,and they came back looking brand new. The flowcharts show them all within 1.9% of eachother. Best of all, it fixed my fueling problems...withthe new injectors in the car runs mint

Re: Y8 Timing
well my car has been down for about a month and is running crazy rich again. ~10 AFR under most throttle. tried several maps including my original basemap. tried maps for my moto and the stock map so its not a map problem. injectors are recently serviced so they should be good. any ideas on the problem? could a loose wire or something with the ecu cause this?

Re: Y8 Timing
It is also making an odd noise. like metal clanging against metal. almost like something is tightened enough. i thought it was some real loud valve ticking, but i just did an adjustment and its still there. I pulled the vtec solenoid and no debris in the filter. ill try to gtet a recording of the sound if needed
