This is what fuel tank looks from above. Be gentle when unscrewing the fuel line. I had to unscrew the other side of the rubber hose.

Both of them came from ebay suppliers as usual. Actually i haven’t bought anything but the rims and a new bumper from Estonia

I bought used Apexi SAFC II on ebay.

MAF ECU and SAFC

On stock car there’s a Mass Airflow Sensor (along with temperature sensor) that outputs pulse output that goes directly into the ECU. Faster pulses mean that more air goes into the intake piping. Slow pulses that little air goes in. So ECU knows at any time how much air goes in and how much it should inject though the injectors (at stock configuration) to make 14.7:1 air/fuel mixture.  N0w, when you install bigger injectors OR raise fuel pressure at fuel rail, you mess up things. More fuel gets injected. You need SAFC or similar to step in. You need to fool the ECU

Cut the signal line between MAF and ECU. Put fuel computer in between that changes the pulse rate. Most cases you need to slow down the pulses to fool ECU thinking it receives less air so it injects fuel for shorter period of time.

OK, now to my problem. I think the SAFC II was sent to me broken. I connected the device to the car’s ECU and tried to start the engine. All i got was backfiring like hell. SAFC was registering Mass Airflow Sensor signal “Kar”. I hooked up my laptop to the ECU with OpenPort 1.3U cable and Evoscan software. I noticed that the ECU registered no air coming in. When i removed the SAFC temporarily, it registered air coming in – ie Mass Airflow Sensor signal was being received.

So i was sure that the SAFC wasn’t outputting anything useful. I took it to my workplace and hooked its input to frequency generator with 50Hz square wave. Output to oscilloscope and got this:

Here is link to SAFC II configuring instructions: Link

Output transistor Q4 needed to be replaced.

Schematics .. kind of

As I did the boost leak test with my own tester, I heard hissing from many sources. If you plan to do this test, google “boost leak tester” for more info on this.

I had these places hissing as i forced air into the intake. Action taken in parentheses:

• Blow-off leaked – really cheap crap that needs to be replaced (new blow-off from Greddy)
• Blow-off / intake pipe seal was leaking (needed tightening)
• Throttle body shaft seals leaked (replaced)
• Injector O-rings (replaced injectors along with the O-rings)
• BISS screw O-ring (new OEM parts)

From this site you can order the seals: http://www.machv.com/throtbodseal.html

FIC 650cc/min

Original fuel injectors and fuel pump must be replaced for more fuel. Original injectors are rated to 450cc/min. The ones i got on ebay were 650cc/min Florida Injector Clinic.

I also had to replace the fuel pump with Walbro 255LPH .  I got the “rewire kit” for more voltage. And one more imortant thing – Apexi SAFC II fuel computer. Since I replaced the injectors with bigger ones, ECU still thinks it is injecting as before but in reality it is injecting much more. Fuel computer fools ECU so that it thinks it gets less intake air so it injects in smaller amounts. To fine tune this computer I got Innovate LC-1 wideband controller that tells you exact fuel air ratio in real time. Chemically ideal combustion will take place when 14.7 parts of air is mixed with one part of fuel. http://en.wikipedia.org/wiki/Air-fuel_ratio
