try adjusting your BOV

 

It's called throttle tip-out. Nothing you can do really. Crome doesn't let you edit it or hasn't found it.

sup.

i know there isnt a tip out option....
but i also know that most pepole dont have this problam...(according to some tuners that use crome)

 

i had it on my car, never thought anything about it, never gave me any problems, sweeps to rich then lean when getting off the throttle

 

It's just a little post fuel. Nothing to worry about.

sup.

post fuel? r u sure?

isnt it the warmup fuel "table"?:S

 

It's "deceleration enleanment," Crome doesn't have control over it. Not much you can do about it, everyone who uses Crome will have it. I had a rich pop after every shift with Crome.

Yes i'm sure.

 

both my cars do this.

my stock injector na b18b tuned on uberdata coupe and my neptuned lsvtec turbo 780cc injector hatch.

i think its just normal, or at least no big deal. it only annoys me right after i get done blasting on it in my turbo car. i will be hard on the brakes and the car is rich for a second still going foward kinda...

 

Add me to the list of people who get a rich pop after every shift.Ever since I switched to crome I have your problem, but I live with it.

 

I believe I had the same issue.

could it be somthing with the gear tables?

im using p30 code for the boost. and i copied the geat values from the p28...

could it have abything to do with this?

what does the gear table do anyway?

 

Basically they deal with fuel trim in gear. As stated, it's not something that's adjustable right now... it's TPS vector related.

Although I must say that since I retuned with the injector voltage offset tables, my rich spike after letting off is much smaller than I'd expect for 1000cc injectors.

If you're worried about the car bucking when you let off the gas, that's more related to the fuel in the 21" and up column than TPS tip-out. Tune those columns and you should have a smooth throttle on/off experience.

 

Does Hondata (or anything) have control over the deceleration enleanment? I'm not looking forward to any pops when I shift..

 

I think it's being overexaggerated... my car definitely does not pop when I shift! It doesn't even hit 10s on the wideband. For a split second it'll dip to the low 11s.

I just had a quick look at the S300 software and it doesn't show it either that I could see. You can download it for yourself at hondata.com...

 

Thx, I am looking into crome/Hondata for my GSR and I hate the sound of a pop during a shift. I just checked some datalogs and I get the same thing with eManage (a rich dip to ~10.5, just after closing the throttle plate, for about .5 seconds) but I don't get any pops.

 

sup and thanks for the info.

ill post my fuel table tommorow so you could see my values....

my car pops if its really getting rich. but my major problam is mpg in city/traffic.

last time i searched i found out that aem ems has that option.

also, calvin (ectune) said that he's gonna have an option to delay the phenomenon or somthing. cant remember exactly,

cui really need to solve this.
