standard z20let map should cope, its got a massive amount of safety built in

[d4nnyk]

When you say "custom rear diffusers to aid aerodynamics" are you going to modify the TAT or replacing?? You can probably guess why I am asking and yes I am a vulture I always seem to miss out on the second hand ones and would one, please don't me

Thats what I was thinking, Courtenay am I certain can tweek it as required to keep it safe them when run in fit the s/c and different map

[The Batman]

thats good news, but will probably just wack nicks on as im sure that will be done and completed and paid for by the time i come back with the monster engine! saves making numerous amount of trips to sunny norfolk the short tat maybe for sale soon i do actually really like the look of it would look better black though

with the harrop tvs do you run a bypass valve to allow the ecu to shutdown things, how do you control knock detection?

Well if you do, I am only a PM away

not yet

i got to supercharge 2 cars in that time aswell as my own

Awwww man! Thats a double blow for you.....























....I'll get me coat

ufortunately they are both male

[vocky]

time scale is to have it all done by february which i think is fairly doable

it's only a couple of weeks of work to sort the engine and sc conversion

but spread over the weekends it will take several months

all the parts have been ordered and i will be hopefully dropping you off 1.5 engines next weekend then the following weekend drop you off all my engine parts thats gives you 4 months to build it and fit it

[chrisvx220]

Wish I had the technical knowledge to understand the details of the engine/tuning going on in projects like this I want but I dont know what I want other than the performance this is going to achieve

[DarrylB]

it's only a couple of weeks of work to sort the engine and sc conversion

but spread over the coldest, wettest, shortest daylight weekends it will take several months

fixed...

Where's that heating got to?

plenty of time then

There is a vent/bypass valve and as to knock I would assume it's still controlled by the ecu as normal

Technically this is just impossible,
It is impossible the stock z20LET knock noise filtering settings would work on a completely different engine.

Let's just hope the stock settings would not retard timing with detecting fake knock as the z22SE (with its chain and its thin liner supports) is a very noisy engine.

Joe you have come far from the days of coming to Worthing with me and James to sort car bits out. I would be interested to pop up or something and have a butchers at what your getting yourself into

Something I did not think of for the Z20LET conversion...
So this implies to me that the knock detection of an LSJ or Saab 207 OEM ecu should be much better suited to 2,2, as it basically is the same alu Ecotec block.
Now where are my LSJ ecu's...

[siztenboots]

Would it help to list the differences between the two? Does the z22 use Saab style ion charge current across the spark to detect preignition? Are both a Bosch piezo sensor? Location in block? Can we obtain the engne noise profile vs rpm table? Is the processing done by ecu or an extra passive filter component?

found out today that the Webcon alpha ecu can use a 60-2 trigger wheel
