Hello It's finally startin to warm up here in Wisconsin So i running a tune a guy gave me and every thing seems fine except for when I let off the gas or slow down . My air fuel runs at 14.7 at idel , 10 - 12 in boost and when i slow down by letting off the gas it goes all the way to the red . Any suggestions ? Crush ? anyone ? Thanks oh I've went about 50 miles on this tune so far 2

that normal for decel....the injectors kinda shut off for a sec on decel so yeah youll notice your afr go off the chart so to speak....its normal

BlueFlamedScion

Oh lol ok Thanks !!!!! Well I switched to your SGLTune Crush . going to try that today see how I like it . I took it for a ride on it yesturday , and it seems like it has more power with it . I can't wait to go to the track

i have to say it but take caution when switching between tunes and watch your afr's...ecu will make its adjustments so it will throw your afr's off for a few miles...careful not to over rev and you should be fine...good luck and have fun bro.

Hey guys, I have something to add with the F/IC setup. I've been playing around with the software lately, and this is what I've discovered...

Our stock injectors are flow-tested to be about 320cc (Thanks Paul) and when calculating your new injectors, you should be using this formula: 1-(320/xxx) with xxx being your new injector size. The output is what you should be using as your fuel trim.

So for example: My new injectors are 625cc, so doing the calculation 1-(320/625) should equal 48.8. This means at idle I should have a -48.8 fuel trim to get roughly the stock idle. When I got this number, I thought to myself "wow, this seems like it's taking out an awful lot of fuel.." because every other map I've seen from others on this board, I see roughly in the 30's for fuel trim. Well I put the numbers in, with an otherwise blank map (so everything should be factory) and the car started but died! After some research, I realized the injector response time is the culprit.

In almost every map I've seen from others here on the board, most people have 486us as the response time.. that is converted to .486ms. This means the F/IC is giving the injector signal .486ms lag time to factor into the injector's pulsewidth. That just seemed a bit too short, considering our injector pulsewidth at idle should be 1.9ms to 3.37ms (Scion FSM). So I tried 1000us or 1ms in the Setup of the F/IC and started her up again, leaving my fuel trims at -48.. and now the car is sitting idling just fine! I waited until the car was completely warm and then hooked up my OBD-II scanner and selected to only see my ST and LT fuel trims. Low and behold, they're almost at 0... well the short term (ST) is at least. My LT now is about 7, but I think that's because I haven't finished the rest of the rpms. I guess more on that later.

I hope this helps some of you.. Oh, and there's no need to enter any values in the O2 map under 14.7psia since the car is in closed loop and not under any boost. I noticed that most people's map have 3.2 or 3.1 to get around 14.5 AFR... no need for that. Only use the O2 map when you're in boost and want to control part throttle AFR.

nice...good work bro

one question though....have you tried a "zero'd out" 02 map?

I would venture to think that it would have to be filled out, i was under the impression that the fic will intercept the primary 02 signal, recondition it and send it on to the ecm...

TCpete

rob thats awesome info man!!!

Crush - I have all zeros in my map that's less than 14.7psia (atmospheric pressure). As per AEM's instructions, the O2 map is just if you desire AFRs other than stoich while in closed-loop operation. Since I want the car to run as close to stock while not in boost, I'm leaving those values "0". In the O2 map in Voltage mode, a "0" value doesn't mean 0.0v, it just means no change from stock. The reason people were using a 3.2 value for idle was because no one had their injector response times correct.. I have a map with the 3.2v values in the O2, my injector response at the AEM factory 486us, and I was idling 14.7 AFR with only -32 fuel... but my trims were all way off.

Thanks, Pete! I'll help you tune once you get yours together. And to answer your PM, I was really lazy and didn't have the stuff wired up for datalogging, but since I have no other alternative, I'll be rewiring my Innovate LC-1 so it can be datalogged with the F/IC.

thats what i meant was 0's in your 02 map...lol


i wish i had my fic back so i could play around with it some more.....so hows your transition between open and closed loop? if you went through all the trouble of figuring all this stuff out i bet your map runs pretty sweet...damnit id like to test it out for myself...if you can send me a copy of your map and maybe i can test it out on Carlanga's car...

B_Real45

So yes, I do have zero's in my map.

I'll send after I do more tuning. As of right now I put the tuning on hold because I'm waiting for my Molex 43030-0003 connector to come in.. I need to install a wire into port 18 on the 22-pin connector so I can wire the wideband. Once I get that one I can start datalogging and finish the tune.

crush02342002

i tried to do that and i never could get the fic to do an internal log of the wideband....i wired it and set it up on the fic but every log came back blank ....well sort of...it would read only one value and stay at that...never changed...my tuner however could get the aux gauge to show afr's on his laptop...so i assume i could have computer logged it but i never had a laptop...oh well...still curious though if you can get the wideband to read on the internal log...

ya know B i think you should start an fic set up thread and get aen to sticky it...im not going to be dealing much at all with the fic anymore since i dont have a turbo anymore plus youv gone above and beyond to share some very good info about it that i think should replace this thread all togather.

B_Real45

No turbo?? what happened??

I got laid off so i needed the money...so all hobbys either got sold off or put on the back burner.

i did manage to get another job though...i was about to go to a very low paying job but i got a call monday of this week from another contractor that wanted to hire me....so yeah i went back to what i was doing before getting payed the same amount pretty much...i do want to boost again but its going to be a while if at all...this time though i want a full standalone...lol

B_Real45

Wow dude, sorry to hear. I'm glad you got another job though! Hopefully Dezod's quasi standalone will be ready by the time you're back to boosting.

crush02342002

iTrader: (2)

prolly...cause its going to be a long damn time

Question,

So i got my car tuned less than a week ago,

and my AFR's were running between 13 - mid 14's when cruising

then today my AFRS are running between 14 - mid 15's when cruising

Can it be because Of the 20Degree Temp raise in my area?
