Get off my back guys, it's a long old drive back from Bill's. Just got home
Firstly, Bill, the WMI threw a spaz as soon as I left your place, ****** thing..........
Bit of a mixed bag of success and failure today.
First I whipped off the front bumper to fit the 90degree alloy bend with WMI boss welded in (thank Bill). With that on and the nozzle (medium sized) screwed in place we did a smoke test.
Smoke was pouring out around the alloy mid section of the B5 TIP, which was quickly sorted by a few turns on the jubilee clips. There was no smoke escaping from the FMIC pipework so that was a nice surprise as I'd convinced myself it was leaking
Got the minge on the rollers and went for a dyno run. I'm sure we did a straight forward run just to see what improvements the Toyo cooler and new fuel pump made but I cant seem to find those results (maybe Bill can post up if he has them.
Anyway we messed about with the Revo settings. Currently the Boost was on 7 out of 9 and the timing was on 4 out of 9. Bill tried boost on 9/9 to see what we got.
Boost pressure was a scary 28psi and the wheels were spinning on the rollers giving me a lovely reading of 320bhp
Bill dropped the boost setting to 8/9 and sprayed some glue on the tyres to keep them on the rollers. This time we got a staggering torque figure of 326.5lbft
Check out Run 5 at the bottom:
Bill was impressed as he'd not seen a normal K04 car with these mods make that much torque but I was scared and asked him to drop the boost back to the 7/9 it was on when I arrived. I'll turn it up to 8/9 as soon as I get my rods changed over.
So with nothing to do with the boost without risking a bent rod Bill looked at the timing side of things. The Toy core was doing such a good job that he turned up the Revo timing setting to 5/9 and did another run. This gave some nice results too as seen above on run 5
274.3 bhp
306.7 lbft torque
So, happy with that Bill started looking at the WMI which had been disconnected at the pump till this point. He had a small amount of Meth left which filled my tank about 3 quarters full, I need to buy some soon. He then adjusted the controller settings so that the WMI came in gently around 11psi then full whack on 20psi. This seemed to reduce the cars power slightly and Bill had seen this on a Seat recently. He suggested we tried the small nozzle as this cured the issue on the Seat.
So in went the small nozzle and he went for another dyno. The WMI LED started flashing, I pointed it out to Bill and he aborted the run. We dug out the AEM kit instructions to find out what 3 flashes of the LED meant. It means the following:
"Pump Driver Shorted
Trigger condition: Current exceeding 15A on driver output.
The status LED will flash a count of three and repeat. The pump driver will continue to drive the pump. If the open is repaired the controller will function normally. Fluid flow may be lost in this condition"
Annoyingly things were looking good (run 3 shows a good holding torque line, before dyno was aborted) and this was with 2 and a bit degrees of timing in unisettings.
I fannied about with the wiring under the rear seats but the only thing that stopped the LED error was to cycle the ignition, then it would error again as soon as the pump started flowing
Bill took the timing out until I find the issue.
I've now got to try and find this issue before I can use unisettings and add the timing back in. So tonight's task is a bit of googling for anyone else who's had this issue. It only occurred when we swapped to the small nozzle
Anyway here's the separate graphs:
So I'm happy i've got bundles of torque, and can have a load more once my rods have been changed. Little bit annoyed with the WMI side of things but I'm sure I'll get that sorted soon. It looks like 290bhp is still a long way off and even with the other mods I plan to do I'm starting to think that 300bhp from a K04 just wont happen. Oh well.
