Hondata

Hello names ej and I'm new to this hondata stuff. I'm currently using the k20a2 greddy turbo kit 550cc calibration and I doubt that its running right. My main problem is that after I drive around and the car warms up the Rpms will drop too low and stalls the motor. Also sometimes it will randomly bounce the Rpms from 1500 to 2500 like my iacv isn't functioning properly. I Have checked all if any boost leaks as well as my iacv and it is in working order and clean. Please help with a calibration good enough for daily with some decent power gains. The closest place to me that tunes is 4 hours away. I really don't want to change any of the parameters risking a motor. I have listed the mods that I have below.

05 civic si hatch (ep3)

Mods:
K20a2
Rc550cc injectors
Turbonetics t04b S 50 trim
2" piping from turbo to intercooler then 2.5" to manifold.
Tial 38mm wastegate 7.25 psi spring T'd off from brake booster.
Log style turbo manifold
Hks ver.2 bov
2.5 exhaust piping

i dont have a calibration for a k20, i have a b series fully built turbo, you need to adjust fuel trim, duty cycle, and air fuel. if you dont have an aftermarket wideband o2 sensor, i am using the AEM digital uego wideband and i love it.

you really should have the car tuned properly if you dont know what your doing. but if your good with the hondata software and understand the fuel trim and duty cycle and all that jazz then you should be able to monitor your car as its running with a laptop. i have the s300v2 and its probably different than the kpro your hopefully using. anyhoo hope i have been helpful.

happy boosting!!

I'm very near of your setup

I'd happy you to share me your map for me to compare

Thank You

alright now i have done some minor tuning with a friend of mine who knows alot more than i do on this tuning stuff.

He couldn't tune my car because there was something wrong with the fuel delivery. Every time we changed the fuel table and then uploaded the cal nothing happened. it still ran the same way like it wasn't changing the fuel table. we upped the fuel about 25% knowing it should run rich to see whats going on and nothing changed. are we doing something wrong? do we also have to change something else?

my cal is currently the same as the k20A2 greddy 12ohm 7psi calibration that the hondata software provides.

You need to make sure that you are adjusting the fuel tables in the section where the car is actually running. There are 6 fuel maps for the low cam and 6 for the high cam. Depending on what cam angle you are running it will read from different tables.

is that the one were the graph is? if so we were changing those and nothing was happening we even upped to fuel 25%. this is what we did.

currently off the greddy cal
changed the tables and at WOT we were at 13.5s with the a/f
stopped changed the tables
turned the car off then into the on position
uploaded map
turned the car off and then turned the car on for 5 sec and started it.
drove it and it was the same.

we redid this process several times and kept adding more and more fuel.
are we doing something wrong? i checked my fuel pressure and it was running fine.

i was contemplating on testing out the "k20a2-rsx-550cc3ohm-cyber-10psi" and see if i run different with the tables. if i do then i know i am doing something wrong and its not my car. if nothing changes then there should be something wrong with my car.

note again my injectors are sl4-550 rc injectors stock fuel rail, regulator, and pump.

Change the rev limiter to somethign low like 2000 rpm and then upload and see if you have a 2000 rpm rev limit. If you do then you know it is uploading and you are just making changes to the wrong fuel tables.

yeah i mean we changed add the launch control and it works fine. would you happen to know which tables i need to change?

oh i fixed my idling =) i just adjusted the valve duty cycle adjustment and works good.

also wanted to add that it drives fine when im not under WOT. i max 6-7 psi and at high speeds it hesitate and doesn't pull as hard sometimes it would and sometimes it wont. i attached the cal from where we left off. you can see the high table changes. are we doing something wrong? and i attached the greddy cal as well so you can compare

There are tables for each 10 degrees of cam movement. You need to see what cam agle you are running at in the section you want to change and only change those cam angle fuel tables.

so we should be changing the cam angle fuel tables as well? i think we were just changing the low speed fuel and high speed fuel. would we notice a difference if we changed just the high and low speed fuel tables without cam angle tables?

hey Spunkster i appreciate you helping me out with this btw. Glad to see there is people out there to share some input. i attached my cals as well to the previous msg

There are 6 low speed fuel tables and 6 high speed fuel tables, one table for each 10 degrees of cam rotation. YOu must see what degree the cam is at and adjust the correct table.

well we were just trying to add fuel to an existing cal. when i was at WOT i wasn't getting as much fuel as i should be so we were raising the tables and nothing was changing. my buddy told me with the kind of setup i have i shouldn't need to change the cam angles that adjusting the high and low fuel should be sufficient and should make changes.

HI thank you
Is someone able to confirm this map is available for my PRA ecu?

Is there any way to change the whole 6 maps, either slopw or high speed? And maybe the whole 12 maps in one time??
