Well messed most of the day trying to tune a Evolution 8 with a nice assortments of aftermarket parts. The main culprit of most of the day tuning was installing the Haltech PS1000 and getting the car to idle good with the PTE 1000cc injectors.
Towards the end of the day we finally got the car running well and were able to steady state tune the car and also do some pulls on the street up to 18psi.
We will continue with this vehicle later this upcoming week so stay tuned.
Got a little more done on the PS1000 maps today for the Evo 8. Client is looking to drop the car off tonight so we can further tinker with it to get the tune spot on before we go to the rollers for the power pulls.
ReplyDeleteSo far the car start a little sluggish, but once its warm the drive ability is pretty goood.
Moved to a different basemap and copied the steady state sector and latency values of the fuel table to the new basemap.
ReplyDeleteWith this new map I got the fans to come online as they are supposed to and also the AC compressor to shut off and start accordingly.
Went to the street by my house and managed to drive the car around and check the transient values around town. This car is really starting to wake up. Will be moving to the mild boost regions later on tonight.
Got to the awd dyno today and loaded the Evo on the rollers. Made a couple of passes and had a couple of issues.
ReplyDeleteThe main one was that it was creeping a good bit, wanted to hit 25-26psi and it was going to 29psi.
Claudio let me know where my mistake was on this issue. Apart from this issue the AFRs were spot on but the power was not there for the psi it was outputting.
330whp on a DD. Called the guys over at Forced Performance and they said that it was down on power at least 100whp. There had to have been some kind of restriction or something wrong in the motor. All the attention pointed to the Perrin crank pulley, so when the client whom had worked on the installation started to check some things around managed to skip a tooth on the belt and since we did not have the special tool for the tensioner that was the end of road today for the Evo on the rollers. I do believe that he is going to get a OEM crank pulley back on there and a harmonic balancer and try to put it all back in synch again.
Got some videos of the dyno pulls today on my camera and I will upload soon.
Thanks again to all that have helped us with some of the pointers and suggestions.
