id2000 SD2.5 no working

[dsmlights]

hey guys I am helping a friend of mine on his car. So I convinced him to go SD as he is planning to make 1000 whp plus. His previous setup was 120 lb injectors on pump gas.

We put ID2000 and e85 on the car. The car fires up fine with the old tune although it is really rich.

I built a tune for him as per the Demo from HPtuners for the 2.5 bar. The problem is that the car starts and dies right away. I did a small log and I don't see no ms for the injectors. Can someone please look over the tune for me and see what I have done wrong. I scaled it 25%

Also the only way to get he car back to start up is I put the file that was originally on the car

I'll look tonight.

Does it still have a MAF? Really need more info on the setup... Return fuel system? Displacement? Cam specs?

[dsmlights]

the car has id2000, fuel return with twin pumps. I want to run a base fuel pressure of 50psi. The maf is still plugged in order to use the AIT sensor but I 0 out the complete maf.

Also it is a 441 cid

[DSteck]

A) Why not just run 58psi?
B) You need to set the voltage offset table for a return style system. That means that whole table gets the same value in every column.
C) You didn't change the stoich AFR value for E85. It's probably dying because it's way too lean.



It's hard to say anything without a log.

i got the car to start and idle fine , I put the values back in the mafHZ. So I am guessing my maf is not failing and going to SD tune. Can someone please check this out for me.

DSteck I did put the IFR flat is there anything else I need to put flat ??

[DSteck]

I just told you... the voltage offset table needs to have every column be the same.

You need to check the codes and post a log. Otherwise, this is flying blind.

holy fuq,,, i can't believe i missed flat lining the offset table on the TT car!! arrrrggg, no wonder your maf program was showing huge swings! LOL

anyways, to help the OP out, set your fp to 58 psi, then take the 0 kpa column and copy it to all other columns.

if you are keeping the fp at 50, which i dunno why, you will need to adjust the ifr and then use the -60 or -50 column and make all the values the same as that.

ok here is the file with the Volt stuff done. Look at the log it starts and dies. I tried adding tons of fuel to the VE and all it did was add more fuel at crank and shut off again. If I put the values back in the MAF the car idles and revs up fine. Can you check to see why my maf is not failing correctly I think that seems to be the problem

[DSteck]

We can't see codes from a log. You need to check that yourself. I don't know why you are zeroing out the MAF anyway. There's no reason to do that.

You STILL haven't corrected the stoich AFR value.

Also, you need to check SES Enable for P0101, P0102, and P0103. You can set those codes to 2 - No MIL Light.

I have no codes I am also using the Beta Version. I am zeroing out the maf because I am 2.5 SD tune. as per the demo it says the maf could be zero out.

[DSteck]

There's no point in zeroing out the MAF table.

If you don't have codes, you aren't failing the MAF. Set the codes like I told you and fix the stoich value.

A) Why not just run 58psi?

You do realize the 58 psi is only really needed in dead head systems, right? It's prefectly acceptable, and sometimes even better, to run 45-50 psi on the return systems.

There's no point in zeroing out the MAF table.

Zeroing the MAF guarantees there's no look up for it. I zero them all the time in SD tunes.

Yes, but ID provides data at 58psi and not at 50. Because they don't give data points for the format he's got, I'd personally rather run at 58psi. Those injectors will work fine at that pressure, too.

I'm aware of why people do it. There's also no point though. When I run SD setups, I just check for the CEL. If I see P0102, then I know it's in SD and I don't think twice.

not disagreeing, but what are the advantages beside making the injectors smaller then what they where flowed at?

if the car does look up the value, is it better to have the correct one there or a 0, would the car suddenly stall if it sees a 0?

if the maf value is correct, i would keep it, if not, then i would just 0 it like you said.

The IFR is scaled. Doesn't matter if their data is run at 58 psi.

You're right they would run at 58 psi, but anytime I work with injectors that large, I'd rather turn the pressure down so I have less fuel to deal with @ idle.

[DSteck]

IFR isn't what I was concerned with. It had more to do with the voltage offset.

[edcmat-l1]

IFR isn't what I was concerned with. It had more to do with the voltage offset.

Voltage offset is such a small percentage of total injector time, even at that low speed, lowering the pressure is not going to skew the operation so much as to cause an issue. I'd rather deal with the dead time with the lower pressure than keep the higher pressure to assure the "values" are correct.

[DSteck]

Personal preference. I'd rather just run at a breakpoint on the data, but that's just me.








Back to the actual topic at hand... OP, you aren't failing out the MAF. That's really all there is to it.

[dsmlights]

I set to everything u told me . What is next step

[edcmat-l1]

Give this one a try. Not sure, but try it
