Im waiting for my 3/8 GM eflex adapter fittings before i fit my sensor.
Anyone know how and what wires are used to go into the haltech ecu?

 

Update: I was away on vacation for 3 weeks. I gotta say that driving in France is awesome. Everyone stays to the right depending on speed, and only uses the far left lane for passing. Traffic flows so well & everything just works! Beautiful.

Rob had to order some more parts and wait forever for them to arrive. This week they will be digging in and installing everything. Then the tuning starts...

Until then I've been driving my little 1.6 diesel VW rabbit pick-up truck. Even with the turbo & fuel turned up, it's pushing maybe 80 hp. Maybe. Best run is 17.9 @ 75 mph. Oh well. at least it gets 45 mpg.

 

Mine is being tuned next tuesday.
Anyone got a e85 map for haltech already ?

 

Here is the latest: My car is almost done! This project has taken longer than expected, but this is the first time Rob has done anything like this, and he is a perfectionist. The return fuel system is in, the Vortech is installed, the ethanol analyzer is plumbed in, and the Haltech is up and running. Rob spent many hours teaching the Haltech what to do based on E% content.

Drum roll please... Here are the dyno results:

Pump gas (91): 420 hp / 340 tq
E85: 462 hp / 368 tq

Since this is on the stock block and rotating assembly, we decided not to push it further, even though there is more power to be had. That will have to wait for phase two: a built engine that can handle (more) serious power.

I should have the car back next week, so then I can assess the drivability difference with the E85. Look at the graph below and notice how smooth the curve is on E85 vs. lumpy on 91.

Can't wait to get some seat time...

smoothing is 5. you should ask for a graph with 0 smoothing if you really want to look at the shape of the curve

You might have bad plugs or weak ignition.

 

Wow almost exact same as mine !!! 420HP pump gas, and 462HP on E85.. I was thinking i would have more of a power jump than 40HP... mine is fully built engine, forged rods/pistons, BC Stage 2 cams, Rev up oil pump, all new oem parts, ARP main and head ect

Want to swap maps and see what our tuners think of the others tune?

I have Walbro 485 pump, DW1000cc injectors, -8 supply line, full -6 return inc inside fuel basket. Did have AAM rails but one corroded and fuel sprayed out everywhere, lost 45L in 10mins... So now i ordered CJM with fuel dampener.

 

Graph
- this is with boost leak issues, wouldn't hold past 11psi , what psi u running ?
Also along with the rails im getting Mishimoto dual pass oil cooler

 

My boost is at just about 10 lbs at 7000 rpm. Again, since this is the stock block with 120K on it, we aren't going to push it with a smaller pulley, etc. If you look at my dyno graph, there is a separate box at the bottom that shows boost.

Are you using a Haltech ECU? If so, we should be able to trade maps. If not, I don't know if that would work.

It's interesting that our power levels are almost identical. Pulls hard as the revs climb.

Do you have any issues when it's cold? Mine runs a bit rough and sometimes stalls out when it's cold. Runs amazing once the engine temp gets up past 140.

 

Yeah Haltech plug in pro ecu replacement (new one), i did have issues when it was cold. tuner fixed that. maybe u can find something in my map to help PM ur email

 

This is neat stuff. Subscribing for updates.

 

how's the e85 tune running so far? What clutch are you using?
