From up against the inside of the adjustment screw tower..[/QUOTE]

Thank You fasteddie!
I've checked my distributor and is 95mm so it's about the same width.

I thought about it and my first choice is to try a bigger fuel flow pump, maybe this one:

https://www.aemelectronics.com/products/fuel-delivery/high-flow-fuel-pumps/400lph-metric-inline-high-flow-fuel-pump





As You can see on the chart at 6.4 Bar fuel flow should be over 300 liter/h, this is the control pressure on my car.
The 2 original bosch pumps have a maximum of 95 liter/h at 8 Bar.
My pumps are a little noise and I should replace them anyway soon.
I think that this is at the moment the best test I can do.
Before replacement I would do some tests with bottles posting a couple of photos and numbers here.

More progress.. 1st What do you guys think of the mounting of my IAT sensor ? Any reason this shouldn't work ?

Also I"m pretty sure the source of my high tach reading is electrical noise.. Anybody have some suggestions as I have converted to the MSD 6A Will I need some sort of noise suppression circuit ?

Is that the stock intercooler?

Air needs to flow through the open element of the sensor, I'm not sure it is going to mounted there. If you are using the stock intercooler and therefore the intermediate manifold/BOV housing, then I would remove that manifold and drill/tap as close to the throttle as is suitable and provides clearance.

Maybe it thinks it is seeing a half speed cam sensor instead of a full speed crank sensor?

I am thinking that it's a noise problem.. I have it set to Basic Trigger.. Is there any other setting I should/could be changing ??

There is a setting for tachout speed. have you checked that?

Cold = traction problems even in 3rd




Lot of miles on the car this year as my daily and it has done very well..
It could use some work here n there and maybe a couple upgrades but has been a great success..

Hello there!
Little question: How much "ma" should have a CIS in order to have no fuel at all also at full open throttle?
This question because my idea is to have some fuel only at full boost when the car is on LPG.
From 0.5 bar of boost AFR become lean.
I'm going to create a dual map, one for gas only, the second for LPG with different injection timing and some fuel to help AFR only in the boost area.

I know, It would be necessary bigger system also on LPG but I would try this way first for 2 reasons:

1- Difficulty in finding larger injectors that can be controlled by the ECU.
2- When the car is on LPG the gasoline lines, injectors and fuel distributor are not flushing and the temperature rises to much.

Hi and Happy Holidays,

Good question, I don't know
For KE-Jetronic (CIS-E) I would try for the default fuel cut setting of -45MA and test
it can be set to go down to near -100MA in the tables if needed

Hi
Sorry, I've been trying to keep the technical discussions on FrankenCIS public for the benefit of the community, so I turned off PMs pretty early in the project.

For specific information on the components we supply, contact Mike at Dkubus here in Australia
sending an email to info@dkubus.com will get to him directly.

For general tech stuff not already covered (or hiding) in this huge thread, ask away

I understand the frankencis basic module
I understand the ms3 needed to manage everything
I understand the option with the lambda control as a target

But what is the purpose of the dpr module ??

Additional question
I have an electromotive module dedicated for the electronic dual spark control

Can this be done with the ms3 version (control the 6 dual coil, crank control and map to adjust advance)

Instead of having 2 ecu to manage 1 will be perfect (ignition plus digital wur)

Thanks for your help

MicroSquirt - or anything else in the MS2 family is required for FrankenCIS control, the MS3 cannot be used unfortunately.

The DPR is only used in the KE3 or third generation of K-Jet/CIS
these are mainly Mercedes and VW/Audi vehicles from the 1990s
Porsche only used Gen1 (WUR) and Gen2 (lambda) systems

My 928 and FastEddie's 924 turbo are customised upgrades using Mercedes parts and the DPR system, I believe we are the only two crazy enough to do this so far.

Stay with WUR or WUR/Lambda and you can totally ignore the DPR module

MS2/Microsquirt has a maximum of 4 ignition channels, so 3 could be used in wasted spark mode, but it might be a downgrade if you are currently controlling the 6 pairs of coils separately.

It depends on the UTCIS version, they made several different configurations, some good, some bad.
if your UTCIS has a separate controller and uses the grey fuel injector and Mercedes metal can pressure sensor, then FrankenCIS might be able to control it.

the microsquirt is here https://www.diyautotune.com/product/microsquirt-engine-management-system-w-30-wiring-harness/
