Hi Scott, Honnestly I had not seen the doc. But it has given me the thought that heater is pwm driven. If it's a matter of driving the heater with +12V, a logic level digital output and an enough powerfull p-channel mosfett would do the job. Correct me if I'm wrong some of the aux outputs are logic level on storm. Kerem

Hi Scott, Thanks for the immidiate reply. Agreed for the injector wiring. and yes it has 60-2 trigger wheel. For the electronic thermostat I've found some info for the same gen 6 cylinder engine. There's a 12watt heater in the middle of the thermostat assembly, when you supply voltage it heats up the tstat so that tstat opens. Now I'm trying to figure out if it's on/off type or pwm driven. Thnaks, Kerem

Hi there, The plan is to run bmw m62b44 non vanos engine on g4 storm. As storm has 4 ignition and injection outputs, igntion is going to be wasted spark and injection is going to be multi point group. How should I wire in the injectors? If two per channel, should I pair the same ones just like the coil pairs for wasted spark? Or should I use one injection channel per bank? which one is better? Do I get any benefit by using the cam position sensor? M62B44 has electronic thermostat. What is the way to run it with g4 storm? Thanks for the help in advance, Kerem

First of all, thanks to pc link quick tune function; all fuel map was finely tuned in 6 dyno runs and some interpolations. with perfect results. Engine is BMW M30B35 turbo with compression lowered from 9:1 to 8:1 with 380cc injectors, stock 3 wire bosch ICV. Now my only remaining problem is engine stalling on overnight cold starts. it starts perfectly, rpm increases upto 1400, after 3 seconds suddenly it goes below target idle rpm and 8 out of 10 starts result with a stall. What I feel is after startup step duration completes, it gows down to idle base position directly without any steps. Is there anyway to make this decrease in steps? If yes, how? If no, what is the solution? increasing antistall gain for low ect?  Thanks for the help in advance. Kerem

Ah! I didn't notice that. Thanks for warning.

Hi There, The aim is to get rid of boost and AFR gauges and display the info on cluster gauge LCD on BMW E34. Sending the data to LCD is a matter of an arduino and some code. My question is; does G4 storm stream this data through rs232? If yes, what are the parameters to capture this data?  Thanks, Kerem

Hi Simon, Â Yes, I'm running of the crank trigger only. As both injectors are group fired and coils are wasted spark, there's no need for a second trigger. Â OK I'll check both polarity of the reluctor and arming voltages then let you know. Â Thanks for the help.

Hi there, Car is E34 5.35i turbo with 380cc injectors and Audi S4 individual coils running @ wasted spark mode. Engine has 60-2 trigger wheel with a brand new VR sensor.  There was some misfire problems but I cleared all. Now the engine runs just like a hi tech engine coils are brand new, spark plugs are brand new, injectors are brand new, no compression problems and sooooo on.  But there is still a misfire problem between 1500 - 2000rpm. I drove the car for a couple of kilometers logging mode enabled and when I checked the logs I realised that at the moment that misfire happens ignition dwell drops to zero although it's set to 3ms. When I check the forum for old threads I found one in which you guys claimed that the problem was with dirty crank trigger signal. But when I check my log for trigger errors the number of trigger errors is ZERO  So what else can cause dwell time to drop to zero? urgent help is highly appreciated.  Thanks, Kerem

 Hi Simon, Now I have misfires around 1500 - 2000rpm with very light throttle. when I feel the misfire and increase the throttle a littlebit everything is just fine. Let me summarize what I've done to fix it: Distributor to coil on plug conversion: I've installed Audi S4 red coils and 4 nail Bosch iridium spark plugs. configured it to run wasted spark. Now the engine runs much more smooth, But still the misfires are there. BTW coils are tuned to have 3ms of dwell and spark edge is set to falling just as vag owner claim. Lucas 300cc to Bosch 380cc D3 injectors swap: Engine is running just like a modern engine. AFR is more stable then ever. But misfires are still there. Valve adjustment control: there was no problems with it. Tried with a more conservative and more stable ignition map: Car didn't pull as good as the original map, but misfires are still there. Changed fuel pressure and fuel master duration assuming that some type of resonance happens inside injectors causing causing them not opening properly: Nothing chaged. misfires are there in exact the same band. Disabled lambda control (from the past experience I know it was creating problems with megasquirt): No change  Hard pulls from idle to max rpm are just fine. thus, I assume there should be no problem with cranck sensor.  Is there any other point that I should check? Thanks, Kerem Â

Hi There, Finally got my car running by G4 Storm. First of all, I apologise for the following funny explanation At idle instead of running like booooooooooooooooooooooooooooooooooooooooo engine runs like booop booop booop booop always following the exact same frequency. BTW its not a non fucntional individual cylinder. When I increase the throttle engine runs OK or at least I don't feel the problem. Â injectors 1+3+5 are connected to fuel1 and 2+4+6 are connected to fuel 2. there's a single factory bosch coil driven by bosch BIP373 igniter. trigger 1 is connected to crank vr sensor. CLT and IAT sensors are correctly connected. Fuel table is so so properly tuned that engine has around 13.5 AFR at idle. Idle valve is correctly tuned. Â Do you have any idea of what I'm doing wrong? Â Atacched is my pcl file. Â Thanks in advance, Kerem bmw-m30.pcl

It just worked  Thank you

Hi There, Car is 1990 BMW 535i (m30b35 engine) turbo with stock wiring harness to which I'm making a motronic 55pin connector to link g4 storm connector adapter. Engine has 60-2 crank trigger wheel with a reluctor sensor and it has ignition system with distributor with a cylinder identification sensor on 6th cylinder ignition cable which I assume is also a reluctor type. * May I use this cylinder identification sensor as cam trigger? Do I really need it? If yes, what should be my trigger 1 and trigger 2 settings? * My future plan is to switch to wasted spark coils. At that time there won't be a cylinder identification sensor. then how should my trigger settings be? Thanks in advance, Kerem

Is it possible to do it in software level? Storm has 4 analog inputs and I have to use one for wideband afr.Â

That's what I definitely saw through scope   Thanks very much for the info.  BTW another question; My FPS has only signal main output (no signal sub). Is going to be enough to operate?  Best Regards, Kerem

Hi Dave, Firstly, I don't have the link e-throttle controller. Car is 1990 BMW E34 535i Turbo. I haven't set anything up yet with g4 storm yet. Megasqirt 2 is installed on it with another electronic throttle controller. Before parting out the legacy ecu, I need to clear those kind of things up so that, I don't waste too much time struggling to run the engine. Now the throttle controller I have is made of ST L298 h-bridge motor controller IC which has two PWM inputs. If the duty cycle on input a is equal to the duty cycle on input b then motor stays on its postition, duty cycle on input a is more than input b then motor moves to another position till duty cycles on both inputs are equal again. And opposite is valid to move the motor to opposite position. Before I try to see the e-throttle output signals of g4 storm on the scope, I just wanted to make sure that I'm on the right way. Unfortunately, here in Turkey, I couldn't find link e-throttle module. Best Regards, Kerem
