Hi guys got my car remapped for my fmic and lost 25bhp 24torque nothing else changed

 

What FMIC was it? Any boost leaks? Did the mapper comment on if it was taking less ignition etc?

 

Japspeed fmic Mapper was andy f said no leaks even blocked dumpvalve of he said temps are the same as my last map

 

Said turbo is spooling but i have lost 25ft/lb between 3000-5000rpm

 

maybe you had it mapped first time on a cold day, the ambient temperature is quite warm still

 

Andy said no real difference in temps dont really understand much about that side of it mate

 

did you not ask him why he thought it had lost power as he is a very experienced mapper and would probably know much more than us lot on here

 

He said fueling and temps were fine he seems to think its fmic he said to take inlet hose off and check for play on the turbo but he doesnt see it been that

 

well id start with what andy says, if you have lost bhp and the only thing that has changed since last map was intercooler odds on thats the problem.

 

As above. Sounds like the FMIC is the problem...

 

Cheers guys

 

From what Andy F has told you it sounds like there is an increased pressure drop across the FMIC...........maybe the core is faulty?

Doesn't af use that deltadash mapping?
And as we all no if on rollers depends on whose etc etc was bonnet up last time is air filter not getting fed same amount of cold air etc etc
What power you at? Ie do you need fmic ? What model and year engine/ car if standard?

 

Dont know what he uses mate but my car is always road mapped

 

Would contact japspeed and see what they say about there product not performing.

 

So how accurate do you recon road mapping readout s are?

 

It'll say he name on the sheet he gives you budd
I'm not saying there not acurite btw as af is the man but I'd think about that before I started to spend more cash!
How does the car drive? It will be slightly laggyer if (that's a word )

 

dont think it matters what the readouts are.

same car , same mapper , diff intercooler and lower power output.

clearly the fmic is the weak link ??

dont think it matters what the actual figure is,the fact that its lower than previous figure from same car and same mapper is the problem.


speak to japspeed mate imho ?

 

I was that fed up i didnt even ask andy to print the graph off been offered alone of a sti tmic then andys going to do a power run for me

 

Hi there

We run Japspeed FMIC at 490bhp without the problem.

What turbo you are running ?

Jura

 

Turbo is aet td05-20g mate 7 months old

 

When the mapper said the fuelling was ok was he comparing it with previous figures obtained with the TMIC or just as a general statement when mapping with the new IC?
If he found that it needed less fuel than before then it would follow that the airflow was down and consequently, lower power result.
I use a Japspeed FMIC but mapping was done in conjunction with a bigger turbo so no before and after figures could be compared. It's accepted that the FMIC will increase lag over the TMIC but once stable will it actually FLOW as much air as the top mount? Are there any comparative figures available?
It's said that once you aim for over, say 400bhp, you should consider a FMIC and it's just to control charge temps but not increase airflow. With all else unchanged, it doesn't surprise me that you see a power drop but 25 bhp does seem rather a lot!

Ok guys took the car to have the intercooler system pressure tested its mapped for 1.5bar but it started toleak at 0.8bar not japspeed fault joiners not tightened up correctly will this be the problem

 

Surely the mapper would have seen this quite clearly

JohnD

 

John i thought it was just the turbo spooling louder but now the clamps are tight its holding pressure and the noise has stopped dont get it

 

doing mine soon was gonna get motorcycle clamps for me

 

Im still waiting to see if the hoses been loose would have cost me to lose 25bhp

 

Hi Peter

I would yes this will cost you loose at bhp/torque side

I would speak with Alyn@AS Performance about the Murray clamps which are made for high boost applications

Hopefully you will get this sorted


Jura

 

Thanks jura this is why i didnt slate japspeed as i now know it was user error

 

Can't believe your mapper didn't look into this for you.
