A finished tune I hope. Cant Wait

 

Minimum on the LHU is 272*, is the 240* on the LNF the min or max?

I'm thinking maybe we need to ditch the Bosch E69 and just convert the LNF's to run on the E39 ECM. There's plenty of good tables supported already. Boost control, fuel pressure, injector timing, stoich, etc.

 

Can I haz an E85 tune also??

 

"Minimum" on LNF is 160*, and "maximum" is 240*.

There's nothing wrong with the E69 per-se, just that nobody seems to want to support it. The same tables in the E39 more or less are in the E69 too.

And one advantage it has over all the Delphi cals I've seen is it supports and implements a factory wideband.

 

In preparation for the E85 frenzy... here is a list of every E85 station in america... according to the feds... Hey the government turned out to be good for something after all...

Hey Vince.. My father works for delphi and is an engineer there. If u need any info on somethign he might be able to get it for you

 

I go to the track almost every weekend, so its not like I am missing too much (:

E85 is really going to help with the 110 degree temps here in AZ

everyone is gonna have an orgasm soon

 

Looking forward to Vince's dyno findings...

 

^^ Me too.

 

Too late

 

E85 tune & EFR TC/Cam setup - one of us in the forum will definitely hit the 10's or 9's!!!

 

awaiting vinces dyno numbers

 

Quick update in between family commitments on this sunny weekend:

248WHP baseline on my bone stock HHR SS, untuned

301WHP tuned on 92

335WHP tuned on 100% E85

(!)

I couldn't really see the torque gains because my clutch is so iffy as it is, and I had to start my runs at 4000-4500 RPM.

Full report to come later

 

Nice gains for sure!

I've found the LNF (using 91 octane...) to be knock limited and MBT was no where to be found as I was only capable of running 13* up top, at most. No crazy boost pressure either.

FWIW, I found on my own stock car (HPT+ E48) that raising timing above 23* netted me a loss in power. Could very well be different on other cars.

What kind of timing did you use in order to achieve what you did with E85? When did you start to ramp it in/where was peak?

With regards to longevity of both the motor and rail/injectors, how will opening the injection window affect things?

 

What mods on the hhr vince?

 

Nice gains Vince!
Was that on a completely stock HHR??

 

LNF is most definitely knock limited on 91 oct gas.

He said his HHR is bone stock, that means (or should mean) no mods.

 

If it's bone stock then HOLY ****!!! wonder what numbers a lightly modded LNF can achieve?
Looks like I will be needing an upgraded clutch next!

 

So you had an 87hp increase by just playing with timing and tuning for e85? That's impressive.

 

Yes, my HHR SS is bone stock. It made more power tuned on E85 than any bolt-on modded LNF I've dynoed at the local dyno.

 

Good work Vince!! Can't wait till you release it for the 09-10 LNFs

 

I found the best power at .88 lambda and 20* total advance at the top end. I tried 21*, that resulted in a loss. I tried .90 lambda, that resulted in a loss. I tried .86 lambda and it was almost identical as .88 so I stuck with .88.

I expect taking the approach of opening the window vs, say raising the rail pressure (all my testing was done at stock rail pressure of 2200psi) will result in less wear on the high pressure components. I've heard of one person having problems with the high pressure pump from raising the rail pressure, and others (including myself) have had unstable rail pressures resulting in periodic P0087 codes.

I also had a chance to try the injection timing stuff on another LNF that was tuned for gasoline on the dyno - advancing the injection timing had basically no effect on the power.

We can offer these tunes now for all LNFs (if we're doing the tuning). The layer isn't finished for 07, 09 and 10 yet, though.
