Fortuitously you have a BGB while. You'll find huge sections devoted to diagnostics and troubleshooting. That's where I might start off. It will eventually information you much better than pretty much anyone can. To the rich AFRs you will want to be wanting around the circuits with the O2 sensor, MAP sensor and coolant temp sensors.

4a. I might declare that it is most likely prosperous at idle as the extra air leaking thru the throttles is dropping the manifold vacuum as well as ECU is incorporating extra gasoline. I discovered that once I got my throttles adjusted the right way, my ISCV had to open up Numerous much more clicks.

to begin with I'd my map sensor connected on the vac nipples together the bottom - giving it a single feed, what i forgot to try and do is the same for that fuel reg, and run it off among the list of fittings over the s/t ITB's.

There is certainly A lot speculation on what does and won't work with aftermarket cams and VVT Manage. Some report past a particular period the pulleys retard the timing too much, citing factors including valves touching pistons from the additional ignition progress.

I attempted tuning it with speed density, rapidly gave up and went for alpha-n which can be how Most people tunes these items (Whilst For those who have the money and dyno time, you are able to do a mix of pace density and alpha-n)

Add to estimate Only demonstrate this user #twelve · Nov fifteen, 2007 blah.. People are biased responses. considered one of The rationale toyota alter to MAP is coz It can be more cost-effective to make. In addition, it makes me laugh when people today take a look at the AFM remaining a restriction.

All ECU’s use several sensors to ascertain load. On the other hand the method used varies amongst engines as the Silvertop utilizes a simple Vane variety airflow meter while the Blacktop works by using a more intricate vacuum (MAP) and throttle placement (TPS) for more substantial throttle openings in which there isn't any vacuum.

I am here in cape town, and not long ago when accomplishing a dyna operate following doing some Focus on my exhaust and several air filter goodies i managed to acquire my "engine output" As outlined by an incredibly here precise dyna to 117kw.

I tested every little thing Along with the BT guide Chapter 8 - FI, but can't locate anything at all Improper. The vibration is even worse with a/c turned on. Occasionally the car just seems to operates wonderful and afterwards following a couple miles It can be vibrating all over again and running truly seriously poorly, lacking loads of ability.

.. it absolutely was Just about slightly carbyish once you initially started if it absolutely was parked outdoors over a 2 deg early morning.. cranked fireplace and give it some little revs over the throttle - then it would idle at 800.. when warm it would head to all around 900. (thats how i established mine not less than)

as for standalone it is senseless to me to grind off tooth that provide additional information to the ecu the more tooth the greater... and using a dizzy is not perfect for crank sign since the belt stretches because the engine revs...

wow. to prove my stage a man from Manila opened up his ST and operate MAP BT ECU taken off the AFM and dynoed the car, the one difference is the ability band is a little bit distinctive but no advancement on how agressive the map is. also his gas mileage sucked, so he went back to his Preliminary/authentic established-up.
