New here
First off, I don't own an EVO, I drive a 1998 Rx7 Type R. (pictures attached).
However, I have a lot of respect for the monster. I have registered here on behalf of my friend. He drives a 1999 JDM EVO VI. BTW I'm from Bangladesh.
Let me first list the drawbacks we have here in Bangladesh.
1.The ONLY octane available in our country is 87/89 RON, NOT RON+MON/2.
2. We don't have any proper mechanic/dealer here for such vehicles.
3. We don't have a DYNO
4. We don't have anyone with knowledge regarding tuning
That being said, following are the list of things his vehicle has.
1. HKS catback
2. Apexi CAT
3. Apexi SAFC II
4. K&N Hi flow air filter (STOCK air box removed)
5. HKS SSQ BOV with recirc kit
6. HKS EIDS
7. Innovate A/F gauge
8. Defi Boost and Oil temp meters
9. Walbro fuel pump and fuel pressure regulator
10. Greddy Profec E-01 Boost controller
He is running a completely STOCK ECU (not reflashed, not chipped)....Completely STOCK.
His car idles funny, fluctuates between 700-900 rpms, the innovate A/F gauge moves from 11.5-17.5 while the car idles. However when he boosts the A/F lowest we have seen is 12ish. Boost 1bar (low setting), 1.4bar (hi setting).
I was having an argument with him regarding his setup. Can you all kindly put down your thoughts regarding the setup. Why is the A/F acting funny? Any idea what should be done to make the idle rock solid and to get an optimum setting for the A/F. What kind if A/F ratio should we be looking for at idle? Higher Rpms with 1 bar boost? Should he even be running 1.4bar?
Does he need a Walbro fuel pump with his setup? What about EIDS? Since he already has a SAFC II, moreover his BOV which is VTA has a recirc kit.
Sorry for the long post. Hoping to learn a lot from you guys.

welcome!
he's got a lot of mods on it.
best thing to do probably is read up on the 'ecuflash' forums,
get a Laptop computer and the wire to connect it,. should be able to balance things out

Or check with some of the tuners like Jestr and see if he can get a e-mail flash, if its available for the 6, I would suggest a fuel pump, and just work your way to a safe air fuel with the safc II but thats just me 
without someone with proper tuning knowledge....ditch most of that stuff. The HKS air filter and the SSQ BOV are the most likely culprits of the poor idle. (I would wager money on that) Return to stock airbox and BOV.
Fuel pressure regulator seems unnecessary. The pump will require the SAFCII to tune it to the correct afr.
You are correct in your assumption that this car needs a tune. Theres not much more to say. Either return it to full stock. OR remove the HKS airfilter/bov and tune the safcII for the fuel pump. Then you can run a little more boost (but not much without better fuel) nothing over 21psi.

Thank you
Thank you so much, althemean for taking your time to reply to our queries. I'm most positive after searching the forum, that the air intake and the BOV are the culprits, many people in this forum previously have faced the idle stalling issues....and now you have confirmed my thoughts.
1. Should he put on his stock BOV or should be buy the IX Evo OEM BOV?
2. I'll ask him immediately to put on his Stock Intake Box.
3. Can you kindly guide us on how the SAFC should be tuned, or how it should be set to make corrections to the A/F ratio with the walbro fuel pump(he also has the OEM fuel pump, he bought the walbro only after a friend of his suggested him to do so)? Can't he just remove the SAFC from the equation, reason being the stock ECU with control the injector duty cycle anyways, that way with the walbro fuel pump, he'll remain in the stock range, why wont just removing the FPR and SAFC work?
4. I'll ask him to be even more conservative with his boost, maybe 1 bar or 1.2 bar when he ditches most of the parts, as you suggested. Reason being we don't have good quality octane, the engine will knock and the ECU will compensate by retarding the timing anyways.....whats the point?
Of what he told me, the stock FP is around 36psi and he has just turned the FP a notch to 37psi. What I fail to understand is with all the drawbacks its kind of pointless to fiddle with the car, he should just keep it stock and enjoy driving.
What are your thoughts on getting the ECU flashed in our case? Should we even attempt that, taking in account that none of the people here in Bangladesh has any kind of tuning experience?
Sorry for the long post. However we are pretty much stumped here and need your best advice.

Tahmid

Q8_EVO: Salaam. Thanks mate.
hawaiian_evo: Thanks!! I love my 7. I'm sure the problem here in our country is much worse. We don't even get air filter, oil filter, spark plugs etc let alone other parts, all of these have to be imported.
A little update: My friend have removed the following items.
1. HKS EIDS
2. HI Flow intake
3. HKS BOV
4. SAFC ( althemean: i know you asked us to tune the fuel via SAFC, however till we get a guidance as in how to do that, we will stay away from it)
I only fear too much carbon buildup with the bigger pump, so need help with the SAFC
Thanks to ALL who suggested that. Special thanks Althemean, ZEUS and Speedlimit (BoB). So you guys have a first name database of the users in this forum? Any link to that? Hate using screen names.
Now that the stock BOV and stock air intake is in place, his car idles rock solid. No fluctuations. Runs so much better.
I have another question, is it possible to get the EVO VI ECU flashed via mail? I believe recommending vendors in a thread might be a big NO, if thats the case can any of you guys let me know via PM?

dude how do you maintain that rx beast? my friend had one and he spend most of his time under the hood then driving it.
plus i hear oil and other things must be changed every 1000 miles or something like that.
but still i wish i could afford and rx and keep up with the maintanence

Thanks.
I wanted to post a couple of photos of the E6, so here goes. Sorry for the crappy photos. Will post better ones soon.
finally after reading up a bit, I have decided on the following. Kindly put in your thoughts.
1. HKS full exhaust, decat-------already in the car
2. K&N induction kit-------have it at home
3. Greddy E-01-----already in the car
4. Walbro fuel pump (255)----already in the car ( will remove the fuel pressure regulator)
5. Innovate LC-1 (to keep an eye on AFR)----already in the car
6. RALLIART ECU---need to buy
Will limit the boost at 1.1 Lo and 1.3 High. If needed will set up water injection.(bad fuel in Bangladesh) Only reason I am thinking of this setup is because there are no tuners here in Bangladesh and obviously the RA ECU is just plug and play.
Waiting for your suggestions.
Best Regards
