It's back in the workshop (my garage). I will have a few weekends coming up where I can see what I need to do to get it running. But a top line list is:
1) install drive shaft
2) complete fuel bucket install for return system already plumbed
3) install meth pressure pump, reservoir and conteoller
4) pressure test intercooler system
5) get tuned for big pulley and big injectors for e85
6) or do a blend with smaller injectors and an e85 controller
Not sure what the state of affairs is on tuning or controlling for e85 blend.
Probably need wheels. Oh and a center screen and apple car play.
Also, anyone have any ideas or product forwards on the fuel bucket options for return-style? I have an aluminum hat but there were issues finding other parts, if I remember. I have to try and re-learn whats in there right now.
BLUF: Believe they are, but unfortunately, I would not recommend them.
Details: I have an M113K in my Crossfire, with a 7G MCT transmission. All of that works, and has been working well for quite some time. I wanted RaceIQ to tune out the "E55 Hiccup", which I was assured they could easily do. This was my main goal. More power was not needed, nor really anything else beyond a relatively simple setup of 630cc injectors, KillerChiller, and a 180mm lower pulley. Previous tune from another vendor already had the power and driveability about right. The hiccup was the issue. It is an annoyance with the 722.6, but with the wet clutch setup of the MCT, it makes for a horrible driving experience. I digress.
After waiting several months, I received a tune from RaceIQ that instantly made the car run worse in almost every way, with top end power being substantially reduced. The Hiccup was still ever present. When I relayed feedback to them, I received another tune - 4 months later and after more than one inquiry - which did nothing to address the hiccup, and made less power than before, with oddball driveability issues. Not too happy of a customer. Wound up just going back to the tune that I was running for years before I paid Race IQ, and chocked up the loss as a lesson learned.
Additional info: Still looking for a solution to the hiccup. Contrary to popular wisdom, it is not supercharger clutch engagement (will do it with the belt off the SC!), and it is not the 82mm TB (tried the stock one). Jury is still out on it, but both the Crossfire and my E55 do it. Just a lot more tolerable in the E55. To be fair, my original tuner was unable to tune out the hiccup, either. The car does run far better on that tune, though.
anyway- some progress on remapping the routes for the IC as I remembered something from years ago wrong and paid for routing I can't use. So I'm redoing it with the existing pieces.
the IC is not front to back (single pass purchased a long time ago) -I know that seems obvious now. Anyway - left to right.
This stuff is pretty straight forward. The routing for pre and post IC water will be perfectly acceptable with the dual heat exchangers I have in the front lower area and I am keeping all oil cooling exchangers as well.
The central challenges are still the fuel pump baskets, routing that to the existing return inputs and outputs under the driver's side and figuring out the all important Venturi tank transfer and the level sensor
Making some head way......that's good !!!
Looks great ! You ever get the supercharger pulley issue taken care of with VRP ?
I can't really remember at this point, lol. Ill
get the belts and see what I have. Yeah there was some form of alignment issue so I have to open that box and see if it's more in line now.
So I guess asked and answered. Since I have steel suspension I do not need the stupid rear upper camber the monkeys at UDP designed wrong. I can just get the ubiquitous non airbag types all over the internet for 150 bucks.

As I have always been straight forward about - most vendors especially the ones that need to make money on 500 units instead of 5000 or 50000 units don't care and probably aren't smart enough to find out there is a problem before you do.
But I was also idiotic enough to buy. So there's that. I should have noticed the problem before I bought them.... years ago.
Okay. Another problem solved.

Ran into an issue with the center support bearing ID. Found the right 32mm ID bearing (6006/32) and ordered so I can get that in with the new guibos.
Rerouted the new duel lines behind the heat shield in a different way so the headers have enough room. Exhaust is all v-bands so that was pleasant to disassemble.
Gonna try to find a nice place to tap for a simple boost line to the ADJ FPR just in case I want to use it depending on how the car is tuned.
I don't think I will need the 1000cc injectors I bought from ID. Maybe I'll sell them and get, what, 750s? Dunno. I'm not going to max effort this thing. Just whatever the bigger bottom pulley provides and some meth/water to cool it (clutch less explained many pages back).
Controlling heat will just extend reliability and not be the main axis of power creation.
e85 was the original reason I did bigger injectors. If it's all e85 it should be fine for 1000cc but it should still be tuned to be able to run on 91 in an emergency.
I am a very long time tuner on another platform (SRT4), and I always tell customers to run the smallest injectors and the smallest turbo they can get away with (within reason). The reason for doing this is that the larger the injector, the poorer the light-load driveability and idle stability. This is due to the inability the ECU will have of metering out really small amounts of fuel. It is indeed a resolution problem. On the turbos, I like small, because the quicker it will spool, which is what actually makes the car enjoyable. I get it that the turbo portion is not applicable here, but the injectors are. For E85, the easiest way to pick an injector is to figure out whatever the max fuel rate you would need for straight gasoline, and then add 27%, as that is how much more fuel you will need to flow for E85. Typical injectors for the M113K are 550 and 630cc/min. Given a 27% increase for E85, you will need 700cc or 800cc/min injectors to match these typical values on E85. Indeed, 1000cc is overkill. If you have the ID 1050x injectors already, you may was well use them. They are excellent injectors compared to many others in that class.
The 1050's were one of my preferred injectors on the other platform, but not sure how the ME2.8.1 will do with them. Pretty small pulsewidths at idle. On E85, probably OK. On gas? Well, stock injectors are 440cc/min, just to put it into perspective.
I do think an impactful difference will be seen if I can find the right tuner. Or learn the ins and outs enough on the 2.8.1 to be able to see the problems my changes have caused.
I can always just get smaller IDs and maybe try to sell or use these on my DI / Port injection setup on the c7
I actually had larger plans for this car but time passes and I found some other shiney things.
I actually bought WinOLS, DAMOS for this and a couple different ME9.7 ECUs (for M156 work I am about to jump in to), and the Funktionsrahmen for both the ME2.8.1 and the ME9.7 AMG. The Bosch ECU is a complicated one, but in comparison to other manufacturers ECUs of the same time period, they were completely primitive. Honestly, the NGC3 ECU in the SRT4 (a Dodge Neon!) was light years ahead!
I digress. I still have a ME2.8.1 in my 04 Crossfire with an M113K, and I bought all of the above to tune my own stuff. TBH, the aftermaket support I see for these cars is abysmal, given how long they have been around. (Now ramping up for more griping...) It seems that a few good tuners turned out some good calibrations, and then every hack on the planet has pirated those tunes, changed a few things, and are selling stuff they do not fully understand to people, and acting like experts while doing it. I'm sorry to issue a market-wide indictment like that, but it is awful what you see people dealing with. The E55 "hiccup" is what has driven me on this. I've had two cars do it now, and none of the fixes have worked for it. None. My Crossfire is running an MCT transmission, which is essentially a manual transmission with actuators in it. It is very much direct drive. The hiccup does truly awful stuff to the driving experience. OK, rant mode = off.
I do not know who to recommend for tuning your car. EC were the go to guys for the longest time. Then it was RaceIQ. There were others in there, but then these cars got old, and the money to be made ran out, apparently.
I called exactly this several years ago. The platform itself was too small. Sure the engines were in a few models. For a few years. Essentially from 2003-2006.
So it's limited. And if the base isn't rabid, then you get what we have.
No one to blame but myself for taking so long. But if can I'd like to just get to a reliable tune on the 180 bottom/whatever clutchless top.
And found some related sites from words people mentioned.
Just feels like with AI the dumps would be readable and re-installable with appropriate changes.
Yes I understand that AI is not end all be all but I do understand on a professional level that code buddy does make some of this possible, as well as pattern recognition.
I really don't want to have to go down a separate rabbit hole but the trans is a separate ECU and while things are complex it was not as connected as newer cars to the rest of the infra on the car. So thought is maybe the 2.8.1 can be replaced by a modern ECU to run the engine? Just speculating. Probably too many dependent outputs to be easiesh.
On the TCU, there are two good options that I know of. One is a project to replace the EGS52 with a brand new unit called Ultimate NAG, https://ultimate-nag52.net/ I have one of these, but I haven't worked with it, as it arrived just as I installed the 722.930 in my car. A second is a transmission tune from Oz who does not advertise, but does an excellent job and some innovative stuff. He makes the 722.6 truly come alive, and I couldn't be happier with what the gearbox is. Changes the personality.
As for the ECU, a much more complicated affair. Tuning the ME2.8.1 is probably the right answer, but every time I have an issue, Megasquirt looks more appealing.
