Set a reader on the fuel array so you will see on the run the PSI on the fuel rail. If it drops on fuel pressure upon opening gas means that there is a problem with the pump but from what you wrote it looks different to me. Now since you removed the ext pump where did you hang the vacuum that...

Tried the airbox mod but i guess I did it bad (have still in in my box somewhere). It ate so much air that at minimum needed two rounds of minimum idle for extra fuel. Had not much time to run here and there, atm just at 102.400kms or so. Said this finally did some works: - first changed the...

Since you are unmounting the injectors and thereby FP, consider to check the filter below the FP fuel pressure regulator. There is a fingertip filter that chockes with dirt.

Ye, tank is venting, breath hoses are clean and passing. The issue is genenerally from the hoses getting squeezed by the depression cause by the pump plus the warm air coming from engine. Anyway mounted the BMC Air Filter, power goes way better, milleage goes slightly down but not too much. So...

That was fixed by myself, applied 90° brass joints and reinforced hoses to avoid collapses and chokes. Anyway updates. Mounted old filter, no substantial difference, mounted then 4-2-1 exhaust. Less power, in the way that with 4-2-X1-2 appeared like a 2T engine. Anyway did a 240km or so...

Today I unmounted the TP sensor and checked for flaws. No flaws really, if i turn it from zero to max it goes from 900 to 4900 ohm, hence it does its job. I guess that the fact it does not reach 4500 lies in the TBodies themselves, the butterflies does stop too early (but they are done in this...

coolant gets squashed out on engine off because the water pump stops turning. Hence the pression that was kept at bay goes to maximum and excessive water gets pushed out. Said that, if you start with MIN water at cold, it should not happen since water goes from Min (cold) to Max (hot). I would...

what the.. wouldn't have belived if I didn't see it! Well, astounding! On second thought: I see, it's a lithium battery!

Update, after testing the TPS moved on higher resistances, low revs seems to struggle way less on/off but fuel consumption still high (11-12kms/lt). Hence that's not the issue. The fact that struggle less on light gas it's because the engine *feels* the gas more opened than it is really and...

What? 880A Cranking? Not even my 70A car battery throws that o.o sure 880 over 180?

Dumb question: does it run roughly or finely? It may have TBs out of sync that urges to be setted. Other stuff ought to be: 2001 model, depends.. mine is a 2001 registered but 2000 effective with ext. FP. So on that fuel pump you have kinda 4 filters to check in order: 1) tower filter inside...

So, got it back from the workshop, they mapped it, changed the EAPs (external air pressure sensor). Seems to work better, still same fuellage and similar struggle at low revs while driving in the traffic under 10% gas throttle. Less than before, so the EAPs was a culprit but not the only one...

Out of ideas brought it to a prof. Dunno if they did something inbetween, these are the sheets atm. Today will call forth for updates on what's going.

Updates: changed fuel pump with a Quantum FP that fits perfectly. I can smell better exhaust output (less unburnt gasoline), but still some hiccups at low speeds (less than 3000 rpms with <10% gas open). Had an idea: when redoing the throttle body sync i noticed that with or without airbox and...

Continental for Busa starts from conti sport attack 3, 4, conti race attack (street) , contiroad attack and contitrail attack. Ain't cheap but they do their job and do it straight and good. ContiSportAttack 2 are a little underpowered for the outcome of the busa.. I mean that I would be feeling...
