Thanks Mate!

So you would recomment to fit an IAT sensor to the intake pipe right? So do I just find a way to do that near the MAF sensor and then wire it back to the ecu? Is this something that is going to be out of my league? Also, which IAT sensor should I install? Cheers!

Hi Experts,

Will this rom work for my 2001 JDM WRX STI (ver 7 Bugeye) - i believe it is EJ207 (but i may be wrong);

What benefits will i find using this rom? many thanks! sorry if i sound stupid ( i am very new)

Cheers all!

Yes it will, do however look into installing wiring up an IAT sensor on the Intake plenum as your model doesn't have one and this rom is best suited to a plenum mounted IAT.
On another note, been testing this on the 2003 JDM STi and works like a charm. Is the launch setup to be on for part throttle? At part throttle, it holds as set but WOT and launch mode is off.... :?:

An easy way would be to install one on the intercooler (idea is to measure the temp of the air charge post turbo and post intercooler) and use the existing wiring from the MAF mounted IAT Sensor, then rescale the IAT table to suit the sensor you install. Somewhere in the Group N forums are examples of IAT sensors used.

The idle targets are set to 1000rpm by default in the CarBerry ROM, it is possible that the increased engine shake is from coming down from a higher rpm. You could try setting the idle targets down to stock settings and see if that helps

Still doing the same shaking not matter what idle rpm

I think it has something to do with the fact that my SD tune is not even close to ready yet. FBKC Flash CEL works great.

Things I noticed:
- Antilag wont hold the set rpm 2000 soon drops under it
- LC is not working at all even all the options are enabled (tested part throttle)

How are your AFRs at idle when the shaking is evident? Mine was shaking and I found my SD tune was making it too rich in idle.

Throttle input shouldn't matter, Lc rpm shouldn't go above the "fuel cut enable" rpm threshold.

Launch all good now, I noticed my NPS was not a solid 0 when in gear as the switch was loose hence intermittently disabling the launch.

Jdm,adm,edm must have nps invert box checked iirc. Usdm the invert nps box leave unchecked. Anti lag rpm hold will be dependant mainly on how much air you can get past the iacv or how far you have the throttle cracked open.

If I remember correctly I tested it both ways and still no good. I will test again tonight. Anti lag rpm hold worked just fine when I was using the base group n rom but I was not able to make it stop other way than using the clutch and big enough gear to drop the rpm under the threshold. NPS is the key right?

Could you explain why EDM must invert nps? LHD cars like USDM.

Ok... I've got a problem with the SD map, it surges at idle, but only while stationary... The car will idle high when coasting, but as soon as the car stops it starts to surge. Any ideas?

I really think you have a bad iac, its a common problem with subies. Unplug the iac when its surging and I bet it will stop

I have switched IAC valves with another WRX and it still surges...

Edit: I'm going to disable closed loop fuelling and see if it still surges... the AF correction goes crazy when it surges... I'm not sure if thats causing it or if its a byproduct of the surge... we'll see.

Got 03 JDM STI ..
the Launch control didn't work at all.
also,when i started the car with the new map,the rpm was about 1400,pressed the defrost on and off,nothing happened!

Anyone can explain why the anti-lag isn't working?NPS??

Thanks.

converted to this yesterday and other than setting up the knock cel flash incorrectly its been working better than any maf tune ive ever used on the car. thanks carberry. looking forward to more.

Ok, looks like the NPS is making things a pain. Im going to disable its effect on launch control so that it is disregarded. Ill post a def update soon

@Subeboost - I noticed that my antilag would fall out before I tuned the car, once everything was tuned it would hold. Also it will fall out if the car is not fully warmed up. You can also tweak the "idle duty cycle - anti lag active" table and set the anti-lag disable rpm threshold a little lower.

@Mohamamdov - Make sure the car is warmed up completely, the anti-lag ECT thresholds must be met for anti-lag to be active. The idle targets are a bit higher than normal during warmup so maybe thats why it was at 1400, if you give the throttle a quick tap it usually comes down. Make sure your NPS is inverted for the launch control, that setting is under "Miscellaneous".

@02rexwi - im going to post in your other thread with some ideas I have

@unknown001 - sounds good, glad its working well for you

Thanks

Guys, the NPS is purely trans and ecu dependent. You need to look at your logger and find out if it correctly recognizes which gear you're in. If it does, you're fine, if it doesn't you need to invert it.

Jason, if you disable the NPS completely, be sure to check the idle logic as, if I recall correctly, it is used in there to determine whether or not to set the idle switch.

Thanx Jason,
Do u mean,defrost button will not work,until the car is totally warmed up,what is the effective coolant temperature??
Whats the launch control rpm is set to?(i have inverted the nps,will test it tonight).

Regards.

Im just going to disable it at the launch control. That way everything else will function normally. I think I may be using it when I code up the NLTS stuff

The defrost button will work but anti-lag cannot become active until the engine is over the coolant temp threshold specified in the "Anti-lag ECT Thresholds" table.

Launch control RPM is set in the "Launch control Fuel Cut (RPM)" table. Default is 4600rpm

I have this running perfectly now on 2 JDM 2003 STis, just need slight tweaks to the SD MAP Vs RPM Compensations, anyone needing help with the JDMs I am more than willing to assist; least I can do after all the hard and awesome work done by the others.
