2G sd at what point

[1990TSIAWDTALON]

I'm curious as well. Might just have to go that route sooner. Also want to run e85 since it's just up the street

When I switched, I made a leap of faith in ME. I drove almost 20 miles to my only E85 station, filled up, changed my fuel setting to 9.8 and held my breath. She started up and I drove home. Then I started tweeking the tune, timing etc. from my gas tune to a friendlier E85 tune. E85 is what makes my car a beast....a lot different car then on gas.

We have 91 octane here in AZ and E54. When I was running 91 I had to be fairly conservative with boost and timing. Couldn't run over 21ish psi and timing was fairly low. With E54 I was able to up the timing and boost. Big big difference in butt dyno.

Ty for the VERY HELPFUL INFO. Guess that's the next move for me.

wish i had e85 near me

 

[donniegst]

well i made the switch and its all kind of messed up anyone care to look at my log

One thing i worry about in switching is not passing NYS inspection . Right now with DSMLINK i pass with no problem as far as my monitors being ready . Does anybody in the NY area have speed density and pass inspection .

 

[donniegst]

mine will pass but i have a 95
i have my inspector lisence though

 

[Dstarperformance01]

Dang state inspections, I remember those. Here in OK there we haven't had state inspections since 2000 and even then we didn't have smog test. No inspections and E85 everywhere. 2 good things about Ok not much more other than cost of living

 

[donniegst]

I would have to drive 30 miles to get e85

 

[donniegst]

well here it is the new sd set up

Looks good! I would reroute the vacuum lines a bit. The bov should have its own dedicated source.

 

[donniegst]

yea im trying to figure that out i only got the 2 lines on the intake so im not really sure how to rought them i know the map sensor has to be dedicated and my tiny 14b doesnt have one on the housing any ideas would help

Yeah I always hated the factory manifolds didn't have enough vac ports. I used to use a Vibrant 4 port vacuum distribution block tied into the brake booster port. Worked quite well.

I don't think anyone mentioned how much of a pain it is to get SD dialed in. Its a long and tedious process if you want it to work right. Knowing what I know now, I am not going back to SD unless I plan to wire in ethanol sensor to the ECU and let it automatically control fuel delivery. I had a few drivability issues with SD, random stall when coming to a stop and the car didn't seem as responsive. I went back to MAF and switched to e85, I'm now making 426hp with a hta68. I did like a few things about SD but it was too much of a pain without real gains in my opinion. Good luck bud.

Something is up with your ECT sensor, ECU is seeing constant -74*.

 

[boostdawd]

Did u dial in the sensors to the appropriate ecu pins?

ok so stupid me didnt have the temp sensor pluged in but still i cant see valuse for some reason on my log i just did another log here it is thanks for the help

 

[doubleclutch]

airflowperrev should be around 0.25 yours is about 0.37 at idle. The link on your other post asking the same questions WTF will help you dial that in.

 

[donniegst]

yea kinda droping this thread and focusing on the help im reciving in the other thanks
