Cause the weather here changes so much always jacks with my tune they foul a lot same with starting with e85 when's cold u need the copper plugs starts better

 

Even though it cant add timing it can still pull timing right. Is it still safe to use the FIC when running e85? Obv a standalone is optimal but you can still use the FIC right?

 

thats true.. even on mild winter here 40 or 30F it takes more cycles to start the car and thats after lots of enrichment and start up timing from a standalone.. i can imagine how hard it is on high altitude subzero lol

 

cool, thanks for the offer. I'll be at work 'till Wednesday morning, but I'll have a chance to hook it to the car tomorrow night. I'll pm u the info. Thanks again! U too fred, all I wanted was to log fuel trims and timing and figure how to design a gauge or something.

 

Yea I can send you a virtual dash that monitors ltft, stft, rpm, ect, iat, timing advance, and fuel system status (open/closed loop) I made all the gauges - they arent that well laid out or pretty but it does the job

 

Also, cory are you on stock motor??

 

that's what I'm talking about, I suck at designing those lol. Oh and I've been running E85 for about 10 months now.

 

The FIC can pull timing and IMO it's safe for a E85 tune. You could get a better E85 tune by adding timing but I imagine the stock timing curve works fairly well. The ECU runs fairly agressive timing for clean emissions and fuel efficiency and relies heavily on a very acurate knock sensor to pull timing the instant it sees any knock. The best reason to pull timing with a piggy is that the ECU pulls several degrees when it sees knock and slowly adds it back to find the knock threshold. But if pulling a few degrees advance prevents that knock event, the end result is that you'll keep as much advance as possible without that ECU retard event.

 

Personally I don't even use the gauges because my netbook screen is too small but I love the graphs and data maps. I made some data maps for LTFT, STFT and timing so that I can view avg, min and max values for any given load and rpm point recorded during a log session.

To customize a data map, just click on the 'data map settings' button on the tool bar and choose your x and y axis PIDs and range. I used absolute load (5-200) for 'y' , rpm (400-8000) for 'x' and LTFT for one map, STFT for a second and IIRC there was a spark map there already.

Here is an example of a spark data map from one of my random log files:

 

So i took the car out tonight for a few tuning pulls. HOLY S**T! With the added timing the thing runs like a raped ape! Butt dyno says def 15-20 whp gain on same boost (15 psi). Also - found a new way to find knock lol - monitor the ecu's spark advance and watch for it to dip It usually stays around 18-22 deg advance under wot but when it sees knock it pulls a quick 4-6 deg timing. I was able to get it down where I was pulling -2.5 deg at peak tq going off to -1.5 at redline. I made 4 pulls like this and it pulled timing by 2-3 deg around 5000 rpm the last pull. For safety, I ended up settling for -4 deg at peak tq going off to -2.5 deg at redline. I made multiple pulls like this and each time the ecu actually advanced timing a degree or two during the pull as I got towards redline. I had no audible knock or misfire and the thing pulls awesome. Now I cant wait for my bigger injectors, pump, and turning the boost up to 18-20 psi :D BTW - as for plugs used during this run - I picked up a new set of NGK Iridum 2 step colder (8's) on my way home from work. I gapped them down to .026 as Ive previousely had issues with gaps in the .030 and higher on e85. I might be able to open them up a bit to get a little gain - but id rather have them tighter and not worry about misfires and breakup

Oh yeah another cool story - didnt intend to but ended up running a car on the way back from getting E in the city.

This C6 vette, all I could tell was it had exhaust and sounded like it was most likely 6 spd from the way the rpm jumped up before he got on it. Well he kept playing with an ls2 gto on the highway - they went at least 3 times - every time the vette got him by about a bus. So after this is done and the gto drops back, I pulled up to the guy and gave him a little stare down. Obviousely hes like a Scion tc? WTF? SLOOOOWWWW! Sooooo he gives me a ___ as rich boy smirk (guy was def young) and downshifts, so i hit 4th at about 70, no break boost or anything, he guns it and I chase - I started out at least a car n half back and by 125 I had about 4 cars on him

Nice eventful evening - Oh and Ive ran my buddies LS3 C6 6spd (bone stock) before on the old tune (pulling alot of timing) - 45 roll with brake boosting - I only got him by about 2 cars - so I can tell the timing changes def made a big difference :D

 

Oh and if youre gunna dog on street racing - dont bother take it to another thread - this was at midnight with literally no cars within a mile of us on a 6 lane divided hwy - I simply wanted to post that bit to show the difference I saw with the timing changes made. Track numbers will be coming this weekend from IFO Ill have the injectors and pump by than so should be on 18psi or so. Itll be during the day so temps may be a bit high. Also Ill be on street tires (Nitto Invo's) so not expecting a great ET, more just looking to see what trap I can come up with Id just be soo happy if I got it into the 12's haha even a 12.999

 

its nice man.. sounds like you have a nice logging software you have there.. and you made a guy not sleep at night hahahaha! btw did you get your total timing pulling 2 degree?

 

Nah im pulling -4 in the fic. Using this the stock ecu actually seems to advance further pull after pull till it reaches around 20-22* of advance - making the final timing (stock timing - fic retard) 16-18* advance. I had it pulling only -2* in the FIC, however after a couple pulls I noticed the stock ecu was retarding it back to 14-16* on wot - which seems to indicates it's seeing knock. I felt the -4* retard on the fic was safe and produced reliable results I feel it could use more advance in low boost which would prolly help it spool quicker, thus a standalone would be helpful After my final fuel upgrades - thatll be next on my list!

 

And yeah - the vette driver kinda acted a fool afterwards. Im still on stock rev limit (obviousely with the fic) so I let off at about 125, he did a nice ricer flyby and stayed in it till at least 160 :/ Prob thought he won lol w/e makes him feel better I guess haha

Oh and thanks to Fred for his posting of how to use the tables function in scanxl lol - thats how I got all these timing values instantly after the pull without having to do a record, than playback and monitor it. Provides alot better instant feedback

 

how was your afrs, maybe you want to add fuel first if your afrs are in the 12s.. ive heard some feedbacks they get good results running slightly rich on e85.

 

I have 2 step colder ngk vpower! And there cheap!!!

m6af2cel6otc u back up and running we all need to hang out 1 day

 

Cars running but not 100%. I have to go and meet up with mike (elevationtc) and change my exhaust cam and check my clutch/tranny and tune and I'm good to go.

Yes stock motor for me
