Jens_l Posted September 6, 2020 Report Share Posted September 6, 2020 Hi Here is my Volvo 940 turbo with a G4+ Monsoon installed by me. Using stock 60-2 vr crank sensor and a rebuilt distributor with vr for cam sync. Running sequential on the injectors and a VAG wasted spark coil hidden under the intake. Also hooked up speed signal and oil pressure, have wires in the engine bay for fuel pressure sensor but not connected yet. Also stock tacho,iac valve and ce light is working. Took the car to a dyno to get help with the fuel and ignition table. Otherwise i try to learn and tune by myself. It made 202 whp with stock turbo and exhaust at around 12-14(0.9-1.0 bar) psi on E85. Bigger intercooler and bigger valves in the head and bigger cam. So in the winter i will upgrade the turbo and exhaust. Already got 1300cc injectors and a DW400 pump in the tank Still working on cold start and idle. As it supposed to be used as a daily driver but only in the summer. Will attach a log file and setup file. Feel free to take a look and make any suggestions. I know my IAT Wastegate trim table is wrong. b230.pclr log.llg Quote Link to comment Share on other sites More sharing options...

Adamw Posted September 7, 2020 Report Share Posted September 7, 2020 I only had a very quick look over your tune - it looks well set up and your log shows fuel controlling well. Although I dont know these engines at all - one thing that doesn't look well optimised to me is the ignition advance is pretty low in some areas for E85 - especially the big drop of 10degs between the 100kpa and 140kpa rows. I suspect you could gain a lot of torque and quicker spool if that boost retard curve was a bit less drastic. Quote Link to comment Share on other sites More sharing options...
Jens_l Posted September 7, 2020 Author Report Share Posted September 7, 2020 The stock turbo is very small with alot of back pressure in the exhaust. But yeah the ignition advance is probably very safe on boost and the old 8 valve volvo engines sure do like higher ignition advance. But the turbo is going to be upgraded this winter and i probably got a boost leak that i need to find. Quote Link to comment Share on other sites More sharing options...

Tommy940 Posted January 22, 2021 Report Share Posted January 22, 2021 Nice build. I also have a 940 which will be using a link monsoon. Do you have any more Info on what coolant temp sensor you've used, also oil pressure. Any info on using the flywheel sensor aswell, I plan to use this for my ignition input & run it on wasted spark.

Sorry for late answer I use the stock coolant temp sensor, the oil pressure sensor is one cheap ebay/wish sensor not recommended but it's only a simple 10bar 150 psi 5volt sensor. If your car is a 940 with a b230fk/ft the stock flywheel has 60-2 trigger and the stock sensors is a vr-sensor that works fine for me. I know people with other ecu brands that changes to bmw vr-sensors if they are having trouble. Quote Link to comment Share on other sites More sharing options...
Tommy940 Posted March 4, 2021 Report Share Posted March 4, 2021 Do you have anymore info on how you've wired the ecu into the car? Quote Link to comment Share on other sites More sharing options...
Jens_l Posted March 11, 2021 Author Report Share Posted March 11, 2021 I did a complete new harness separated from the lh 2.4 harness and placed the link ecu and my new fuse box where the stock fuel ecu is located. The new fuse box is powered from 120Amps relay that a mounted in the battery location area. On pin 34 in the stock fuel ecu connector there is a speed signal that i connected to my link ecu and pin 22 is for check engine light that i also connected. Here is link for some pinout information jetronic.info Wiki | LH2.4 Pinouts and Diagrams (ipdown.net) link2.pdf Quote Link to comment Share on other sites More sharing options...
