My ED30 runs better on stock map instead of GIAC 305bhp
« on: March 29, 2010, 04:35:56 pm »
With the PUMP mode selected (305) the turbo is intermittent, taking foot off the gas then back on sometimes help, but I can't be bothered with that all the time.

So I flashed the stock map back on, and the car drives normal. Sure, it's not as fast when in boost, but the car at least has a personality then. Turbo works when it should.

Few questions though, is it normal for the boost to have 2 stages? It will turbo around 2.5k but then a second wind at 5k.

Does the boost work more in the higher gears? With the 305 map on, the boost in second gear isn't as powerful as say 4th.

I have given up driving like it's a VTEC i think, took some getting used to, am used to no power until 6k RPM.

Is the boost dependent on how much throttle you're giving it?

in stock mode mine used to boost hard, then around 4500-5500 used to give another slight kick.

It sounds like with your map its showing a component as being faulty maybe that isnt noticeable with the stock boost.

GIAC has lower boost request than Revo so the second kick you feeling is simply due to stock like boost delivery which means the power and torque curve is very linear..

Also the reason for the less boost feeling in the lower gears is due to GIAC keeping the stock torque limit in the first two gears..

Keith @ washsshop (on here) has got GIAC on  his ED30 - he might be able to help tell you how the map pulls.

Certainly with my bluefin it pulls HARD from 2500 right round to about 7000 with no peaks or troughs.

Where are you based mate?

Hissing noise when the car is hot and stationary coming from the front of the car?
