Idle timing?

 

7 degrees

I think this set of injectors has issues. On some start ups the AFR would swing wildly back and forth and it always is sounding like the car is missing a beat every couple of rpm's at idle and even up into the 3k range.

I've hence pulled the injectors back out for I think i risk damage with these guys in. Soon as i did my old 880cc scaling for e85 fired up perfectly and the car returned to a smooth idle. I'm just going to ask for a refund on these guys if i can and hopefully get a set of 1200's from buschur.

 

I had my idle at 8 deg. and the car didn't like it. Bumping it up to 12 deg. made all the difference.

 

hows it coming along?

 

Well the car is back on 880's for now and i'll try and get a different set of injectors this pair is just murder to try and tune up. Start it up and the car starts missing, shut down and start again and sometimes it will idle fine..

I'm basically just going to get something else.

 

Sending the 1450's back to FIC for testing hopefully it's a problem and not just my failure at tuning these guys

Since installation the injectors gave me 300 codes and the sound of the car changed to one of missing every few RPM. Swapping back out the injectors to the 880's solved that problem.

 

^^^^ That is the suck.

I didn't have any issues that bad. They were hard to get tuned on pump gas in terms of fuel trims being perfect - but they never had drivability or idle problems. And E85 was easier.

 

So when you put them in initially the car wasn't stumbling a little?

This does give me some hope i'm not a complete jackass hehe!

 

The car started right up.

Only problems were in some of my bad settings I had really lean idle at start up. I would go out and cruise first and work the mid trims, and then do idle second. It seemed like the ECU could get a hold of the trims better in that order.

What did you have them scaled at for E85?

 

Tried 1008 at first but and the car was still running wierd. I did a WOT pull just because i'm insane and the AFR was 13.0 ..

So I ended up dropping the scaling all the way down to 834 or so to get them around 11.5 to 12. Either way it never ran quite right but no knock ironically.

 

I just love E85!

I just redid my timing map basing it off of MrFreds timing map and now have my timing around 6 degrees at the lowest ramping it up to 15 degrees at the top all at 21psi or 250load cells since I'm still on these pansy 880 injectors until i get them back from FIC.

Power is truely amazing..

I don't care if E85 gets as expensive as premium i'll never switch back!

 

I'm jealous and I hate you

in the most loving way possible

 

thanks bro

 

race gas is better. You have to PAY for the good stuff...it's much like most illegal drugs.

 

I don't remember making a thread on which gas is the best..
