You need emanage to tune it

 

[sarutobi84]

Try install fuel pressure regulator,current fuel flow maybe too high making rich combustion.

A fuel regulator must be install after you changing to Walbro pump...im also get same problems like you after going with Walbro pump last 3 months...im sets 2.3 bar on my SARD regulator & now fuel running too much save & powerful...mines also A/T...

Actually what's the purpose of installing Walbro fuel pump on your "stock" BT?
The stock fuel pump is insufficient for the fuel supply?

As stated above, its recommended to install an adjustable fuel regulator since you've upgraded the fuel pump.

upgrade fuel pump..for future upgrade maybe..he he

before install walbro, i got the problem = more than 50% throttle my car will stall like 1 to 2 sec (feels like no fuel coming). then onli the power will start coming. ask the mech to check here n there cant solve the problem. so i try search in the internet n saw in a forum which they had a problem similar to mine, solution change the fuel pump or fuel pump filter. at tat time, i have no 2nd hand ae101 fuel pump. so decide to get the walbro. tat how the story goes.
but after install the walbro, i din know the fuel consumption so high. mech recommend me get a piggybak to tune, but no budget. rite now cannot tahan already. so seek for advice

As u've said u didnt have enough budget to opt for piggyback, then opt for FPR 1st to reduce the fuel waste...mine also have similar prob b4...beginning with change the fuel pump,fuel filter, install FPR, pour injector cleaner but yet still have the 'chocking' feeling...later cannot tahan edy, take out the engine to do full overhaul and till now, problem solved...that's my experience...it's also part of the learning experience to know more bout ur ride

I'm using a 1JZ fuel pump on my BT auto. I did feel the difference in responsiveness as compared to the fuel pump that came with the halfcut when I changed to the 1JZ pump.

However, I do not have a FPR fitted coz the tuner said no need wor...

For town driving, I also can get only about 330 km/tankful but if outstation driving decently, can get about 480 km/tankful. Quoted for RON 95. When I was using RON 97, the mileage was even better.

just installed the Works FPR, coz no stock for SARD & TOMEI. RM430 includes hose, meter..... watever needed. the pressure is just below 3 bar. my mech try adjust down but seems cannot aledi. so i will just have to wait n c wats the result comes out after a few days of driving.

mine onli drive in penang. Was using Shell RON97 since then.

install FPR to re-tune the fuel pressure..

Forgot to mention that my BT is fitted with a piggyback already; e-manage blue.

Nice... Where did u buy that walbro ? Mine to share.. Wanna buy too.. But takut tak ori.. Kindly advice... Thanks

With ignition n injector setting? My mech recommend me Unichip with a custom extra switch to switch from using 95 n 97.

Yes, fitted with injector & ignition setting. Was tuned when I was using V-Power those days. These days cannot afford V-Power anymore, so using only RON 95. Did not re-tune & no problem; only difference is it's not as responsive as V-Power :(

I did consider Unichip those days but ended up choosing e-manage because more people can tune it; unlike Unichip, very limited place to tune resulting tuning prices being monopolized. Also when I called up the shop to enquire, the boss way of talking damn lansi. So he actually helped me to decide which to choose .

255ltr/hr is way too big for N/A 1.6cc... u will having problem of rise in fuel pressure.
even though u have adjustable fuel regulator but due to the fuel return line are too small , it created back pressure causing the fuel system badly effected.

it just waste of money... 4throttle run very low vacuum, so piggyback on bt engine won't really respond from the map adjustment..

Agreed...
plus with close loop, it somehow make EmB useless...

Wow... looks like you guys have bad experience with Emanage Blue on 20v... I'm sure a lot of other guys would beg to differ as I've personally seen reasonable gains using EMB on a number of rides including mine which is running EMB for over 3 years ;)

As for Walbro, yes indeed its overkill. 1JZ or other OEM fuel pump is not rated at such high LPH as compared to the walbro as walbro is usually used on modded turbo setup or NA setup with at least stage 2 mods.

I'm afraid using Walbro on stock setup will cause in fuel leaks as you're putting a lot of pressure on the fuel lines, be it fuel supply or fuel return line.

Just a quick question, did you check the fuel filter or fuel injector before upgrading the fuel pump? Also, did Walbro solve your initial issue?

Since i already put in walbro, it's a waste if sell it 2nd hand & change to stock fuel pump. the concern is fuel consumption. so tat's y current solution suggested is to use FPR.
by the way, before change to walbro, there is no problem with the fuel pump filter or injector. & tat time i already changed new fuel filter as well. & yes, walbro solve my initial issue. but my guessing other lower LPH fuel pump will solve this issue as well.

With adjustable FPR installed, can it lower the pressure on the fuel lines? i scared as u say will cause leaks. i should always check for leaks from now on.
