So the last week has been frustrating.
Started off with the maps we were using apparently being outdated, but Eurodyne not making the new ones public or known. So a few calls back east and we had new maps on Wednesday.
Things are going well, and the car is driveable. It's putting down 460awhp which is no slouch. But we can tell its got more in it, if only it would stop riching out above 4000rpm.
More calls to Eurodyne and Tapp on Friday, sent them some logs. Oh well they've also update injector constants, battery constants, and MAF scaling. Nice of them to let the public know....again.
This made things a LITTLE better, be we still cant figure out whats going on above 4000rpm. So you start looking at sensors.
o2's are new, MAF is good.
We then looked at the position of the MAF sensor. The distance between the filter and the MAF is like 4". There is no screen in the MAF housing like stock so maybe we are getting turbulent flow due to the extreme sucking going on.
So a solution was devised temporarily
Enter the reason to remove a headlight.
The longer intake tract allows the air to straighten out and become more laminar before hitting the sensor, hopefully leading to more precise MAF readings.
A test late last night at 730 looked promising, but everyone was ready to call it a night and go drinking. So we'll try more on Monday.
ONe of the issues were also facing is the car seems to want to stay in closed loop and doesn't want to go open loop. The place we are getting the issues is right around the cam switching point which is frustrating
