Re: SSS's V8 swap project ... NOT just another bubble! (anymore)

Post by SSS »

update:

tune/closed loop: ok ... finally figured out how to re enable the settings to be able to switch to closed loop!
... PO did a tuning at some place to run without ANY O2 sensors and disabling quite some features ... obviously because the tuner wanted to simplify his tuning job.
but still ... my upstream O2 sensors seem not to get hot enough to allow the pcm to switch to closed loop as early as possible ... it takes quite some "heating all up". Considering grabbing some Bosch 13111 sensors which come with a stronger heater (Corvette downstream sensors) and use those upstream.

tune/auto shifting: tweaked the torque management and the line pressures slightly to allow for firmer shifts with less clutch slippages ... especially 3->4 part throttle was awfully slow ...
and tweaked the WOT shifting rpms in such a way that I can intentionally hold a gear up till cut off at WOT. (it up shifts if I release the throttle slightly below the WOT TPS position ... or do not go WOT at all)
... and I can hold 3 a bit longer than before ... yesss

tune/fan control: lowered ON/OFF thresholds to match my newly installed 160*F Thermostat ... BEFORE my engine was running at 200-210 with 220 peaks depending on load and traffic/offroad ... NOW even with added powersteering and additional transmission cooler both in front of the condenser I was running MAX 200 OFF road ! In city driving I am usually at 190-198 ! (with A/C city driving!)



did some upgrades regarding transmission cooling:

1. my transmission temp gauge was mistakenly mounted to the wrong "colder" line ... discovered that after I started using the Scangauge to read the transmission temp from the PCM (WTF ... offroad 220-230!?)... they were like 50-70*F higher than my external gauge ... now corrected! (but the B&M gauge is still not really accurate and does not show close to PCM readings ... eff it)

2. Hayden 676 cooler in the grill in front of the condenser ... ADDITIONALLY to my under the tub mounted Derale 13960!
NOW ... and with PCM readings the transmission temps stay when warmed up between 160-180*F ... EVEN OFFROAD while DUNE BASHING FOR HOURS ... YEESSS ... (maybe my modified shift tables are contributing to this result as well)


FINALLY took the chance to do something for my powersteering oil temps:

Had ordered for this a second Hayden 676 ... and mounted it bolt together with the additional tranny cooler as one wide unit directly in front of the A/C condeser.
Could not reproduce the fading effects of a overheated powersteering anymore. And last trip on Friday was not a walk in the park ...

I like the new Hayden 676s A LOT ... great quality, RIGHT DIMESIONS TO FIT together into the grill, cheap!
I hope I have hereby ironed out all so far identified weaknesses ... will do some electrical wiring clean up (old jeep harness, aux led light wires, new LED tail lamps, flasher relay, 4-3 wire conversion of my Euro tail lamps ... etc etc) NEXT

btw ... google and summitracing are your friends for parts pics ... will see if I can take good pics of the coolers mounted ... won't be easy, since I have a grill mesh as well

LIWA and DesNAV : sluggy is coming (with SSS) :twisted:

from now on nothing absolutely swap specific anymore ... in other words: THE SWAP IS DONE :mrgreen: ... and this thread complete!

The general "Sluggy Build Status" http://www.ad4x4.com/club/viewtopic.php?f=53&t=15808 is where the journey goes on ... have fun 8-)

Congrats Chafik. You've been down a long, hard road but now you can enjoy the fruits of your labour. No doubt the whole experience will feel very rewarding to you. :D

Thanks Dino!
Actually your experience and your stroker website were a BIG inspiration to me!
The only reason I did not go the stroker way was the necessity to stick to a auto (for my wife) and the crappy 42RLE wouldn't have handled serious torque ...
Tobias' nice Stroker project initially costed him around 20k ... DesertDawg had to iron out quite some wrinkles and surely spent some more kilo AED. So ... a reliable and complete V8+transmission set up for below 40k (I estimated ~30k at early stages) seems quite OK 8-)

And yes ... meanwhile driving the beast since September DAILY ... a number of desert trips ... some of them full days and some even with competition/fun character... minor issues all resolved ... NO SINGLE breakdown in the desert ... no overheating ... and plenty of confidence building power :mrgreen:

So yes ... it is already VERY rewarding and fun ... and finally last weekend I handed it over to my wife for her daily city trips during the week... and she can manage and likes it! :D :?

The last test: summer heat ... but I am sure whatever pops up can be resolved :twisted:

Would I do it again? HELL YEAH! :twisted: :twisted: :twisted:

Chafiq, just a suggestion you should post the whole thread as a upgrade from scratch to finish with pics if possible and put it a s sticky on the forum for future use. Mabrook!

Thanks, man!
Not sure about the sticky :lol: ... it is a epic and very Wrangler TJ specific thread ;)

:lol:
hehe ... at least it HAS a real frame ... unlike the new Jap SUVs which pretend to be off road trucks and have nothing but crumpling sheet metal as chassis

with the brakes I have on my TJ I can fun your fancy old model pathfinder any day for shorter braking distance ... and you do not want to know what happened to desert storms pathfinder once when he "touched" my stock front bumper by accident with his rear fender ... (sorry desert storm!) :lol:

as for esp : crap
as for handling : I want to see your qx4 doing 120km/h on a sabkha without taking off or the shocks exploding :lol: :lol: :lol:

(yes ... sluggy has some more upgrades than just the engine ... genius ... this is possible with a TJ!)
