Did you make up an X pipe from the downpipes to the cats so that the O2 sensor 'sniffs' all 6 cylinders?

The TT pipe has a bolt inserted into the tap below it. Here's some more pics:

Hello to you all, I´m new at the forum!

I have just installed the Turbo Technics kit on my 1990 300CE with the M103 engine.

I have a few questions I hope some of you might be able to answer as I have some issues after installing it.

I wonder about how to set up the fuel pressure regulators. The way I did it was to route the main fuel line to the regulator for the additional injectors, then route the hose from that to the stock fuel pressure regulator. The fuel return line remains the same. I then linked the MAP sensor, and both fuel pressure regulators to the intake manifold. I scrapped all the supplied electronics and replaced them with an ERL MF2 unit.

I got the car running, but there are som slight issues. It seems that however much gain I adjust on the MF2, the AFR readings would go far above 14:1. I would like to get the readings to about 12.5:1. The green light goes on, so it fires the additional injectors, but the car stalls a bit in the middle of the rpm range. This leads me back to the "vacuum" line for the fuel pressure regulators. These were made for vacuum, or am I wrong? I thought that if these got boost, they would actually decrease the fuel pressure?

Also another issue that I encountered was that, whenever under boost, I get a hard spot on the pedal. If I push past that, the car gears down. If I kickdown, the automatic gearbox would shift up and pull all the way to the redline, but it won´t shift down again without me releasing the pedal...Is the vacuum line for the gearbox supposed to be re-routed? The supplied documentation for this kit wasn´t exactly detailed :rolleyes:

Hope to get some help with this :D

Regards from Norway!

Forgot to tell that I noticed the system would not hold the fuel pressure for a long time after the engine was turned off. I would wait a few minutes and when I loosened the nut on the main fuel supply line, it would be no over pressure left. Maybe a one-way valve on the supply, or the accumulator is bad? That way I might not have the required pressure also under driving conditions?

No performing at a dyno yet. I found that it was a bad solder that prevented the ERL from performing like it should. The ERL MF2 is actually very nice, and also 3d mappable via potentiometers. A potentiometer is provided per 1000rpm, it is not stepping, but has got smooth changeover points. You also have the ability to adjust gain and map-sensor threshold. So just as good as the Split Second, but just a bit more "manual" :)
The rubber hose on the TT-cast seemed not to be long enough to reach the fuel return line fitting on the fuel distributor, but fitted perfectly to the original fpr. Do you have any pictures of your install? I know that the manual said otherwise, but it just seemed wrong as the hose did not have the required lenght...And did you install the over boost fuel-cut relay, or just scrap that as well?

As for the transmission, I see that I am not the only one having problems..Jayrash seems to have somewhat the same problem with his tranny. I thought the modulators were designed for vacuum and not boost. I see mine shifting like a charm on low revs without boost, but goes banana on kickdown. Maybe a check-valve might help me out here? :confused:
