MB6 tuning

[spudley1988]

Right chaps looking for some advice here as all this is about to be new to me. When i got my mb6 its had an apexi VAFC controller in it and we lost the settings to what previous owner had it set up by.

 

Now I'm heading up to AVA tuning in Glasgow, unsure if anyone on here has used them but if you have any feedback welcome, but what am i to expect? He said he has dealt with these in the past but they are less common now but he has knowledge of them and apexi products.

 

I personally have no knowledge on the VAFC and have never took a car to one of these places so if anyone can enlighten me to what will go down, what to expect etc id appreciate it muchly.

 

He's charging 65 an hour and reckons he could have it done within the hour.

 

Any help welcome cheers guys.

I don't know if this is any help to you.

 

 

You can change the air/fuel mix if your moving the vtec point but to get the most out of it put it on the rollers! thats about it really! + on there you have loads of live readings that moniter everything like throttle % revs etc,, there a fare bit of money for what they are, but its worth it

About the Apexi AFC Neo

The AFC-neo is a multifunctional sub-computer that allows the tuner to fine-tune air-fuel ratios, calculate MAF/MAP transfer functions, control VTEC or other solenoids, address stall issues associated with open-air blow off valves, and monitor key ECU data.

Changes in air-fuel ratio are achieved by correcting the airflow sensor signal or pressure sensor signal at 16 different RPM points, and at high and low throttle positions, all of which can be moved according to the customers needs. By changing this input signal, the tuner can alter the injector pulse width as calculated by the ECU.

The AFC NEO is unique in the sense that it has a built in MAF/MAP transfer function, which is necessary when the tuner swaps MAF/MAP sensors from one vehicle application to another. By setting the sensor IN and OUT to the appropriate sensor numbers, the AFC NEO can act as a translator/emulator unit, eliminating the need for costly sensor or ECU reprogramming.

The unit also has a VTEC solenoid control function that allows the tuner to change the VTEC engagement/disengagement point on Honda VTEC systems (not compatible with iVTEC systems). The VTEC solenoid control and also be used to control other types of solenoids as used in nitrous-oxide and water/methanol injection systems.

On MAF applications with open-air blowoff valves, there is a deceleration air correction feature that allows the tuner to compensate for the over-rich condition that occurs at throttle-off. By adjusting the MAF signal at throttle-off condition, the tuner can reduce the amount of fuel injected and prevent stalling.

In monitor mode, the driver can monitor digital engine RPM, throttle position, battery voltage, airflow sensor capacity usage, pressure sensor data, Karman frequency, MAF/MAP/Karman correction factor, and solenoid on/off status.

 

 

I would expect him to put the car on the rollers and set up the APEXI to how you want it, vtec crossover etc. Also maybe to take it out on the road to see how it behaves.

Well off to ava tomorrow. Can't say I'm not nervous, prob didn't help I googled the place and the feedback was mixed. In fairness you can't please anyone just hope they are good. Apparently they do have a good knowledge of the apexi thing so fingers crossed.

Also thanks for the description nik appreciate it

Good luck tomorrow mate, i used Triple H Performance down near Troon. They mapped my car and specialise in Honda. Ive been to AVA before and found them to be quite up their own arse but that was a few years ago. If you are not happy with them then try http://www.triplehperformance.co.uk/

Cheers for that mate. Apart from being up their own arse was their work ok?

How did you get on fella?

How did you get on fella?

 

x2, nicely set up now?

Intrigued to know .. I bought one of these for my track civic years ago and never actually got round to have it set up ..

The guy was fantastic, had tonnes of knowledge i tuning cars just lacked enthusiasm lol.

 

However we are unsure if the product has been wired in incorrectly as we could alter v-tec but not air flow even tho we were picking up signals from the sensors so will need to get wiring looked into.

 

We did find out at the point v-tec enters, or just marginally after, it runs marginally lean but then richens back up.

 

When we had v-tec set at 4800rpm we made 182bhp at engine and 162 at wheels. The power curve also wasnt very smooth.

 

So we moved v-tec down to 3800 revs and produced 187bhp which was around 167 at the wheels. Having v-tec come in early also gave an extremely smooth power curve.

 

He seemed impressed with my car which i was chuffed about and he gave me the chat saying they make these cars seem slow at low end so when v-tec kicks in is meant to impress people, however by having it set lower means it distributes the power curve far more effectively in which the dyno proved this.

 

So all in all was very happy with cars readings but slightly disapointed that we couldnt fine tune more, will hopefully sort tho and return in the very near future.

That's interesting. Most tuners move it higher on these engines. Strange tho changing the crossover point shouldn't affect your peak figure.

Is it a standard engine?
