Where would you set your Hi settings.

[Staytuned]

With these mods where would you put your Hi AFC settings? I had another thread about lean problems ...just curious what others have for settings.

T25 set at 17 psi
60mm TB
Buschur UIC pipe with 1G BOV
Greddy 24R FMIC
255 Walbro, AEM FPR set at 43 psi base
lower honey comb removed
Full 3 inch exhaust.

All othere mods listed here: Mods on my car

first think i would do is to put the honeycomb back in. not good for 2g. are u on stock injectors?

what oct. gas do you normally put in your car?

 

[Staytuned]

And stock 450's

without a datalogger i honestly would leave them at zero until i got a datalogger or dsmlink

Look about half way down the page they have settings for your car kind of.

Every car is different.

Go make a log from 3rd 2k-redline.

Then post it up so we can examine you .

That would be the best way for us to help you.

Here is a log I did this week: 4th gear, settings were 0 from 1000 to 5500 then they were +2. EGT's 925 C at top of 4th. My concern is the low timing from 2400 to 3600 rpm. Car feels slugish untill 5000 rpm.

So I tried adding a little fuel from 2000 to 5000 and now she hits fuel cut. Screw it .....this year is almost done anyway. I have a dyno run planned for next week and I want to get the most out of it I could.

damn.

good luck on the dyno let us know how it turns out.

 

[cfisher]

doesn't look to bad. i would add fuel right at 6K. you can probably get your timing to 22 deg or so.

I got it figured out now so that I don't get any knock in the midrange. Part of the problem was a funky MBC that would spike pretty hard......fixed that. Set the boost to 15 psi raised the FP to 47 psi base and added a little fuel across the board on the hi settings. No fuel cut and she pulls good through the midrange.

I 'll post pics and a vid hopefully tomorrow of my run on the dyno.
