Got bored Martin :D

So here's a spliced and diced version. I built a new PC a while back so I haven't re-installed GIMP for image tweakery, but managed to make a transparency and stretch the image so the values on the axis line up.

Bit scruffy as JonVs old one was a scan and I couldn't adjust for the background colour, but it's pretty bang on accurate and well I think it's interesting..... you can see where the power's made at the top end.

I meant I was bored. Are you bored too? Roll on spring and the end of the damp pestilence we know as winter.

Anyway how many PSI boost was it in the end?

Just one question..................how fast does it go mister?
Seriously what does a 400bhp Gta compare to, bearing in mind we know how well the rear engine layout launches, I haven't been in that many 'super cars' probably my brothers old Subaru STi , standard 2007ish I think, 280 bhp?, I'm well experienced with 0-60 in sub 3 sec bikes but that's a different feeling to being in over a ton of mass accelerating.
Suppose I could ask Clee for a ride in JIL when its done this year :D
Congrats, I wish I'd done a bit of dabbling in E200 JVV when it was apart, but never mind, it would have probably still been in bits now !

Nice numbers, well done.

I'm hoping you'll turn up at Macon this year, should be some beasts attending! :sarcasm

Hi Ryan,

It's really easy to drive, good fun, but I fear not good for the points situation on my license... thankfully it's not my car, but my friends, so I will be keeping well clear... but for normal driving I was going everywhere practically in 5th, dropping down occasionally and just touching the throttle :)

Upgrades always available...

Image
see here - viewtopic.php?f=8&t=5612&start=300

... modified ecu ready for 27128A EPROM chip, plus the other electronic mods for a bad Renix 1 :shhh :MoreSarc 6x new injector to match, and the cams... otherwise know as chicken fried rice, no 23 please... :D

Image


Image

from here - viewtopic.php?f=8&t=5612&start=300 . Above parts package supplied to TomK - cams, injectors, regulator, modified Renix ecu with upgraded maps, and matching turbo.

I did an upgraded ecu for Dan and Tom Delorean, here: viewtopic.php?t=6895

.
Update time...

Dan, right here you go, new base board, electronics modified to change the air temp correction coefficients, and the 12 psi boost cut brick wall disabled. Hence, as a base ecu with no map changes this is going to give you more drivable torque as the ignition roll off is reduced, all the modified Renix 1 ecu's out there from me are thus revised. I have modified the board to allow fitment of a 27128A EPROM’s in a chip converter, thus giving you the capability to make MAP changes and blow them into UV erasable ROMs. The chip fitted has copy of the last factory calibration file 601B to get you up and running initially. I have also included an EPROM burnt with some revisions for you to run on an OE setup (turbo, injectors etc), so as soon as you have a feel for the car with the 601B and have shaken everything down, then swap over and give it a bash. You should also be able to adjust the waste gate up for 12-14psi.

Anyway, pictures below, and I'll get it sent back to you soonest...

Cheers,
Martin

I never did hear back with the test on the upgrade to the ecu calibration... so I would be interested in finding a donor to give it a go if you are interested Ryan? This is for effectively a standard motor, than one with cams and turbo upgrades as above, mainly improving the throttle response, mid-range general punch and a bit more top end..

Cheers,
Martin

Just out of interest....mombo combo number 2

F525 overlaid....clearly I need more boost as you've said before Martin. Just shows the difference in power and torque delivery.

Somewhat more clear if I lose JVs brown paper bag scan....

What's interesting is that F50s torque figures are really pretty good - all in the cams and head eh Martin?

I had just posted to say how low the low rev figures were but then realised I was muddling the fuzzy lines.... it's really not bad at all for something that revs like that.

BTW Martin - excellent example of how to keep those revs high:

I'll shut-up now. :silent

That sounds right up my street Martin, I'm hoping to get the car into the paintshop in the next month. If I don't then it'll have to go on hold 'cos although my paint charver is tops .....sometimes things drag on somewhat ! So come what may I want to be driving it again in the spring.
I have a donor ECU, either the 25T one currently on the car or the bodgeorific one that is awaiting de-bodge, I don't want to go down the mega power road 'cos one thing leads to another but I do think there is a bit more to be had, even if its purely drivability.
